This article has been replaced by an official "Disciplined Agile Manifesto".
The text of the original article remains below.
I've recently been working with Mark Lines of UPMentors and we've had some interesting discussions around evolving the Agile Manifesto which I thought I would share here to obtain feedback. Note that this is not any sort of official position of IBM, nothing in my blog is by the way (unless explicitly stated so), nor is it some sort of devious plot to take over the agile world (although if we did have some sort of devious plot, we'd make the exact same claim). What we hope to accomplish is to put some ideas out there in the hopes of getting an interesting conversation going.
Over the past decade we’ve applied the ideas captured in the Agile Manifesto and have learned from our experiences doing so. What we’ve learned has motivated us to suggest changes to the manifesto to reflect the enterprise situations which we have applied agile and lean strategies in. We believe that the changes we’re suggesting are straightforward:
Where the original manifesto focused on software development, a term which too many people have understood to mean only software development, we suggest that it should focus on solution delivery.
Where the original focused on customers, a word that for too many people appears to imply only the end users, we suggest that it focus on the full range of stakeholders instead.
Where the original manifesto focused on development teams, we suggest that the overall IT ecosystem and its improvement be taken into consideration.
Where the original manifesto focused on the understanding of, and observations about, software development at the time there has been some very interesting work done within the lean community since then (and to be fair there was very interesting work done within that community long before the Agile Manifesto was written). We believe that the Agile Manifesto can benefit from lean principles.
Our suggested rewording of the Agile Manifesto follows, with our suggested changes in italics.
Updating the Values of the Agile Manifesto
We are uncovering better ways of developing software by doing it and helping others do it. Through this work we have come to value:
Individuals and interactions over processes and tools
Working solutions over comprehensive documentation
Stakeholder collaboration over contract negotiation
Responding to change over following a plan
That is, while there is value in the items on the right, we value the items on the left more.
Updating the Principles behind the Agile Manifesto
Our highest priority is to satisfy the customer through early and continuous delivery of valuable solutions.
Welcome changing requirements, even late in the solution delivery lifecycle. Agile processes harness change for the stakeholder’s competitive advantage.
Deliver working solutions frequently, from a couple of weeks to a couple of months, with a preference to the shorter timescale.
Stakeholders and developers must work together daily throughout the project.
Build projects around motivated individuals. Give them the environment and support they need, and trust them to get the job done.
The most efficient and effective method of conveying information to and within a delivery team is face-to-face conversation.
Quantified business value is the primary measure of progress.
Agile processes promote sustainable development. The sponsors, developers, and users should be able to maintain a constant pace indefinitely.
Continuous attention to technical excellence and good design enhances agility.
Simplicity--the art of maximizing the amount of work not done--is essential.
The best architectures, requirements, and designs emerge from self-organizing teams.
At regular intervals, the team reflects on how to become more effective, then tunes and adjusts its behavior accordingly.
Leverage and evolve the assets within your organizational ecosystem, and collaborate with the people responsible for those assets to do so.
Visualize workflow to help achieve a smooth flow of delivery while keeping work in progress to a minimum.
The organizational ecosystem must evolve to reflect and enhance the efforts of agile teams, yet be sufficiently flexible to still support non-agile or hybrid teams.
We’re agile – things evolve, including manifestos. Looking forward to your feedback (add a comment).
Updates Since this Was First Published:
At IBM Rational we define disciplined agile delivery as:
Disciplined agile delivery is an evolutionary (iterative and incremental) approach which regularly produces high quality solutions in a cost effective and timely manner via a risk and value driven life cycle. It is performed in a highly collaborative, disciplined, and self-organizing manner within an appropriate governance framework, with active stakeholder participation to ensure that the team understands and addresses the changing needs of its stakeholders to maximize business value provided. Disciplined agile delivery teams provide repeatable results by adopting just the right amount of ceremony for the situation which they face.
Let’s explore the key points in this definition:
- Full delivery life cycle. Disciplined agile delivery processes have life cycles which are serial in the large and iterative in the small. Minimally they have a release rhythm which recognizes the need for start up/inception activities, construction activities, and deployment/transition activities. Better yet, they include explicit phases as well. It is very important to note that these are not the traditional waterfall phases – requirements, analysis, design, and so on – but instead different “seasons” of a project. The point is that we need to look beyond agile software development and consider the full complexities of solution delivery. Adopting a full delivery life cycle, not just a construction life cycle, is arguably the “zeroth” agile scaling factor.
- Evolutionary. Agile strategies are both iterative and incremental in nature. Iterative means that you are working in a non-serial manner, on any given day you may do some requirements analysis, some testing, some programming, some design, some more testing, and so on. Incremental means that you add new functionality and working code to the most recent build, until such time as the stakeholder determines there is enough value to release the product.
- Regularly produces high quality solutions. Agilists are said to be quality focused. They prefer to test often and early, and the more disciplined ones even take a test-first approach where they will write a single test and the just enough production code to fulfill that test (then they iterate). Many agile developers have adopted the practice of refactoring, which is a technique where you make simple changes to your code or schema which improves its quality without changing its semantics. Adoption of these sorts of quality techniques seems to work – it appears that agile teams are more likely to deliver high quality systems than traditional teams (according to the DDJ 2008 Project Success survey). Within IBM we take it one step further and focus on consumability, which encompasses quality and other features such as ease of deployment and system performance. Furthermore, although some agile methods promote the concept of producing “potentially shippable software” on a regular basis, disciplined agile delivery teams produce solutions: a portion of which may be software, a portion of which may be hardware, and a portion of which will be the manner in which the system is used.
- Cost effective and timely manner. Agile teams prefer to implement functionality in priority order [http://www.agilemodeling.com/essays/prioritizedRequirements.htm], with the priority being defined by their stakeholders (or a representative thereof). Working in priority order enables agile teams to maximize the return on investment (ROI) because they are working on the high-value functionality as defined by their stakeholders, thereby increasing cost effectiveness. Agile teams also prefer to produce potentially shippable solutions each iteration (an iteration is a time-box, typically 2-4 weeks in length), enabling their stakeholders to determine when they wish to have a release delivered to them and thereby improving timeliness. Short iterations reduce the feedback cycle, improving the chance that agile teams will discover problems early (they “fail fast”) and thereby enable them to address the problems when they’re still reasonably inexpensive to do so. The DDJ 2008 Project Success survey found that agile teams are in fact more likely to deliver good ROI than traditional teams and more likely to deliver in a timely manner.
- Value driven life cycle. One result of building a potentially shippable solution every iteration is that agile teams produce concrete value in a consistent and visible manner throughout the life cycle.
- Risk and value driven life cycle. Core agile processes are very clear about the need to produce visible value in the form of working software on a regular basis throughout the life cycle. Disciplined agile delivery processes take it one step further and actively mitigate risk early in the life cycle – during project start up you should come to stakeholder concurrence regarding the project’s scope, thereby reducing significant business risk, and prove the architecture by building a working skeleton of your system, thereby significantly reducing technical risk. They also help with transition to agile, allowing traditional funding models to use these milestones before moving to the finer grained iteration based funding that agile allows.
- Highly collaborative. People build systems, and the primary determinant of success on a development project is the individuals and the way that they work together. Agile teams strive to work closely together and effectively as possible. This is a characteristic that applies to both engineers on the team, as well as their leadership.
- Disciplined. Agile software development requires greater discipline on the part of practitioners that what is typically required by traditional approaches.
- Self organizing. This means that the people who do the work also plan and estimate the work.
- Self-organization within an appropriate governance framework. Self-organization leads to more realistic plans and estimates which are more acceptable to the people implementing them. At the same time these self-organizing teams must work within an appropriate governance framework which reflects the needs of their overall organizational environment. An “appropriate governance framework” explicitly enables disciplined agile delivery teams to effectively leverage a common infrastructure, to follow organizational conventions, and to work towards organizational goals. The point is that project teams, regardless of the delivery paradigm they are following, need to work within the governance framework of their organization. More importantly, effective governance programs should make it desirable to do so. Our experience is that traditional, command-and-control approaches to governance where senior management explicitly tells teams what to do and how to do it don’t work very well with agile delivery teams. We’ve also found that lean development governance, an approach which is based on collaboration and enablement, is far more effective in practice. Good governance increases the chance that agile delivery teams will build systems which fit into your overall organizational environment, instead of yet another stand-alone system which increases your overall maintenance burden and data quality problems.
- Active stakeholder participation. Agile teams work closely with their stakeholders, who include end users, managers of end users, the people paying for the project, enterprise architects, support staff, operations stuff, and many more. Within IBM we distinguish between four categories of stakeholder: principles/sponsors, partners (business partners and others), end users, and insiders These stakeholders, or their representatives (product owners in Scrum, or on-site customers in Extreme Programming, or a resident stakeholder in scaling situations), are expected to provide information and make decisions in a timely manner.
- Changing needs of stakeholders. As a project progresses your stakeholders will gain a better understanding of what they want, particularly if you’re showing them working software on a regular basis, and will change their “requirements” as a result. Changes in the business environment, or changes in organization priority, will also motivate changes to the requirements. There is a clear need for agile requirements change management [http://www.agilemodeling.com/essays/changeManagement.htm] on modern IT projects.
- Repeatable results. Stakeholders are rarely interested in how you delivered a solution but instead in what you delivered. In particular, they are often interested in having a solution which meets their actual needs, in spending their money wisely, in a high-quality solution, and in something which is delivered in a timely manner. In other words, they’re interested in repeatable results, not repeatable processes.
- Right amount of ceremony for the situation. Agile approaches minimize ceremony in favor of delivering concrete value in the form of working software, but that doesn’t mean they do away with ceremony completely. Agile teams will still hold reviews, when it makes sense to do so. DDJ’s 2008 Modeling and Documentation Survey found that agile teams will still produce deliverable documentation, such as operations manuals and user manuals, and furthermore are just as likely to do so as traditional teams. The DDJ September 2009 State of the IT Union survey found that the quality of the documentation delivered by agile teams was just as good as that delivered by traditional teams, although iterative teams (e.g. RUP teams) did better than both agile and traditional.
The basic idea behind DevOps
is that your development strategy and operations strategy should reflect one another, that you should strive to optimize the whole IT process. This implies that development teams should work closely with your operations staff to deliver new releases smoothly into production and that your operations staff should work closely with development teams to streamline critical production issues.
DevOps has its source in agile software development, and it is an explicit aspect of the Disciplined Agile Delivery (DAD)
process framework. As a result there is a collection of agile development strategies which enable effective DevOps throughout the agile delivery lifecycle. These strategies include:
- Initial requirements envisioning. Disciplined agile teams invest time at the beginning of the project to identify the high-level scope in a light-weight, collaborative manner. This includes common operations requirements such as the need to backup and restore data sources, to instrument the solution so that it can be monitored in real time by operations staff, or to architect the solution in a modular manner to enable easier deployment.
- Initial architecture envisioning. Disciplined agile teams will also identify a viable architectural strategy which reflects the requirements of their stakeholders and your organization’s overall architectural strategy (hence the need to work closely with your enterprise architects and operations staff). One goal is to ensure that the team is building (or buying) a solution which will work well with the existing operational infrastructure and to begin negotiating any infrastructural changes (such as deploying new technologies) early in the project. Another goal is to ensure that operations-oriented requirements are addressed by the architecture from the very start.
- Initial release planning. As part of release planning the disciplined agile team works closely with their operations group to identify potential release windows to aim for, any release blackout periods to avoid, and the need for operations-oriented milestone reviews later in the lifecycle (if appropriate).
- Active stakeholder participation. Disciplined agile teams work closely with their stakeholders, including both operations and support staff, all the way through the lifecycle to ensure that their evolving needs are understood.
- Continuous integration (CI). This is a common technical agile practice where the solution is built/compiled, regression tested, and maybe even run through code analysis tools. CI promotes greater quality which in turn enables easier releases into production.
- Parallel independent testing. For enterprise-class development or at scale, particularly when the domain or technology is very complex or in regulatory environments, disciplined agile team will find they need to support their whole team testing efforts with an independent test team running in parallel to the development team. These testing issues often include validation of non-functional requirements – such as security, performance, and availability concerns – and around production system integration. All of these issues are of clear importance for operations departments.
- Continuous deployment. With this practice you automate the promotion of your working solution between environments. By automating as much of the deployment effort as possible, and by running it often, the development team increases the chance of a successful deployment and thereby reduces the risk to the operations environment. Note that deployment into production is generally not automatic, as this is an important decision to be made by your operations/release manager(s).
- Continuous documentation. With this practice supporting documentation, including operations and support documentation, is evolved throughout the lifecycle in concert with the development of new functionality.
- Production release planning. This is the subset of your release planning efforts which focuses on the activities required to deploy into production.
- Production readiness reviews. There should be at least one review, performed by the person(s) responsible for your operations environment, before the solution is deployed into production. The more critical the system, the more product readiness reviews may be required.
- End-of-lifecycle testing. Minimally you will need to run your full automated regression test suite against your baselined code once construction ends. There may also be manual acceptance reviews or testing to be performed, and any appropriate fixing and retesting required to ensure that the solution is truly ready for production.
There’s more to it though than simply adopting some good practices. Your process must also embrace several supporting philosophies. The Disciplined Agile Delivery (DAD)
process framework not only adopts the practices listed above, and more, but it also promotes several philosophies which enable DevOps:
- Delivery teams should be enterprise aware, that they should work with people such as operations staff and enterprise architects to understand and work towards a common operational infrastructure for your organization.
- Operations and support people should be recognized as key stakeholders of the solution being worked on.
- The delivery team should focus on solutions over software. Software is clearly important, but we will often provide new or upgraded hardware, supporting documentation (including operations and support procedures), change the business/operational processes that stakeholders follow, and even help change the organizational structure in which our stakeholders work.
- Your process should include an explicit governance strategy. Effective governance strategies motivate and enable development teams to leverage and enhance the existing infrastructure, follow existing organizational conventions, and work closely with enterprise teams – all of which help to streamline operations and support of the delivered solutions.
For more detail about this topic, I think that you will find the article I wrote for the December 2011 issue of Cutter IT Journal entitled “Disciplined Agile Delivery and Collaborative DevOps
” to be of value.

A fair question to ask is why should your organization consider adopting the Disciplined Agile Delivery (DAD) process framework. I believe that there are several clear benefits to doing so:
DAD shows how agile techniques fit together. DAD is a hybrid that adopts strategies from a variety of sources, including Scrum, Extreme Programming (XP), Agile Modeling, Kanban, Outside In Development (OID) and many more. More importantly DAD's process-goal driven approach shows how this all fits together, providing advice for when (and when not) to use each technique and the advantages and disadvantages of doing so. In doing so DAD enables you to streamline your efforts to tailor agile to reflect the context of the situation you find yourself in. Furthermore, it provides this advice in the context of a full agile delivery lifecycle, explicitly showing how to initiate a project, construct a solution, and then deploy into production. Instead of starting with a small agile method such as Scrum and doing all the work to figure out how to tailor ideas from other methods to actually make it work, why not start with a framework that's already done all that work for you?
DAD isn't prescriptive. DAD is far less prescriptive than other agile methods. For example, where Scrum prescribes a single strategy for managing changing requirements, a strategy called a Product Backlog, DAD suggests several strategies and provides advice for choosing the right one. Where other agile methods define a single lifecycle, DAD instead describes several lifecycles (an agile Scrum-based one, a lean lifecycle, and a continuous delivery lifecycle to name just three) and once again describes how to choose the right one for your situation. Your agile team is in a unique situation, and as a result needs a flexible process framework that provides coherent, easy-to-follow tailoring advice. Isn't it better to adopt strategies that reflect the context that you actually face?
DAD explicitly addresses architecture. Even after a decade of agile software development it still seems that the topic of how agile teams address architecture is a mystery for many people. As a result DAD builds agile architecture strategies right in, starting with initial architecture envisioning, to proving the architecture with working code, to evolutionary design strategies during construction.
DAD explicitly addresses DevOps. DevOps is the art of combining development and operations approaches in such a way as to streamline your overall efforts. DAD "bakes in" DevOps through explicit support for common DevOps practices as well as its robust stakeholder definition which explicitly includes operations and support people.
DAD explicitly addresses governance. Although governance is often considered a dirty word within some agile circles, the reality is that software development teams can and should be governed. Sadly, many agile teams have traditional governance strategies inflicted upon them, strategies which invariably increase schedule, cost and risk on the project. But is doesn't have to be this way. It is possible, and very desirable to adopt agile goverance strategies, strategies which are built right into the DAD framework.
DAD explicitly addresses many other important development activities. Architecture, DevOps, and governance are just the tip of the iceberg. DAD also shows how critical activities such as analysis, design, testing, quality, technical writing, and many more are addressed in an agile and streamlined manner throughout the delivery lifecycle. As described earlier, this is done in a non-prescriptive and tailorable manner, thereby removing a lot of the mystery regarding how this agile stuff all fits together into a coherent whole.
DAD is solution focused, not software focused. Although the rhetoric around "potentially shippable software" resonates well with developers it observably and empirically misses the mark. DAD promotes the more robust idea of "potentially consumable solutions". Yes, shipping is nice but shipping something that people actually want to use/buy, something that is consumable, is much nicer. Yes, software is part of the equation but that software runs on hardware, we often also need to develop supporting documentation, we often evolve the business process, and even evolve the organization structure around the usage of the system. In other words, we're really producing solutions, not just software. Isn't it better to adopt rhetoric that actually reflects what we're doing in practice?
DAD promotes enterprise awareness over team awareness. One of the great benefits of an agile approach to software development is its focus on the team. This can also be a bit of a problem, because a team-focused strategy can result in suboptimal decisions for your overall organization. DAD promotes the idea that disciplined agilists should be enterprise aware, working towards common business and technical goals while leveraging and enhancing the existing infrastructure whenever possible.
DAD provides a foundation from which to scale. The starting point for scaling agile is to understand how agile strategies fit together from project initiation to delivery into production. If you don't know how to succeed with agile in a straightforward situation then it will prove very difficult to do so in an agility @ scale situation. DAD not only provides this tailorable foundation from which to scale agile it also takes a robust view of what it means to scale agile (hint: large or distributed teams are only a start).
DAD provides a basis for enterprise agile. As organizations move towards a true "enterprise agile" approach they often find that they need to adopt either DAD as a foundation or invest a fair bit of effort inventing something similar. They are also starting to adopt strategies from the SAFe framework, or reinventing such, as well as ideas from sources such as Enterprise Unified Process (EUP) (sadly, poorly named in hindsight), ITIL, and even CoBIT. More on this in a future blog posting.
In short, DAD provides a lot of proven advice culled from years of experience applying agile software techniques in enterprise-class environments. Instead of figuring all of this stuff out on your own, why not jump ahead and leverage the hard-won lessons learned from other organizations that have already dealt with the challenges that you're struggling with today?
The primary shortcoming of the DAD framework is it makes it very clear that software development, oops I mean solution delivery, is quite complex in practice. As IT practitioners we inherently know this, but it seems that we need to be reminded of this fact every so often. DAD doesn't provide a simplistic, feel-good strategy that you can learn in a few hours of training. Instead it defines a coherent, tailorable strategy that reflects the realities of enterprise IT.
There is a wealth of information at DAD posted at the Disciplined Agile Delivery (DAD) web site and great discussions occuring on the DAD LinkedIn discussion forum. For those of you interested in agile certification, the Disciplined Agile Consortium site will prove valuable too, in particular the list of upcoming DAD workshops provided by several IBM partners. And of course the book Disciplined Agile Delivery: A Practitioner's Guide to Agile Software Delivery in the Enterprise (IBM Press, 2012) written by Mark Lines and myself is a very good read.
My new white paper, Disciplined Agile Delivery: An Introduction
, is now available free of charge from IBM.com. The paper overviews the Disciplined Agile Delivery (DAD) process framework, a hybrid comprised of strategies from Scrum, XP, Agile Modeling, and other agile methods which is people first, learning oriented, and enterprise aware. DAD is the basis from which you can scale agile.
- Context counts - The Agile Scaling Model
- People first - People, and the way they interact with each other, are the primary determinant of success for a solution delivery project.
- Learning-oriented - The DAD process framework promotes the ideas that team members should collaborate closely and learn from each other, that the team should invest effort to learn from their experiences and evolve their approach, and that individuals should do so as well.
- Hybrid - DAD adopts and tailors strategies from Scrum, XP, Agile Modeling, UP, Kanban, and many others. It addresses many of the issues Mark Kennaley discusses in SDLC 3.0.
- IT solution focused - DAD teams produce potentially consumable solutions every construction iteration. This extends Scrum's "potentially shippable" strategy to explicitly address usability/consumability plus the fact that we're really delivering full solutions not just software.
- Goal-driven delivery life cycle - The DAD lifecycle is focused on delivery, not just construction. Furthermore it is goals-driven, the DAD process framework suggests various strategies to fulfill those goals but does not prescribe specific practices.
- Risk and value driven - The DAD lifecycle is risk and value driven. It extends Scrum's value-driven lifecycle which produces potentially shippable software each sprint/iteration so that it explicitly includes light-weight milesstones such as ensuring stakeholder consensus as to the scope of the project early in the lifecycle, proving the architecture with working code early in the lifecycle, ensuring sufficient functionality exists before transition, and ensuring production readiness before actual release of the solution.
- Enterprise aware - The DAD process framework promotes the ideas that DAD teams should work closely with their enterprise architecture groups to ensure they leverage and evolve the existing infrastructure, adopt and follow corporate guidelines, and work to the overall organizational vision. DAD teams are self organizing with appropriate governance.

Recently I have been asked by several customer organizations to help them to understand how to account for the expense of agile software development. In particular, incremental delivery of solutions into production or the marketplace seem to be causing confusion with the financial people within these organizations. The details of accounting rules vary between countries, but the fundamentals are common. In order to get properly account for the costs incurred by software development teams you need to keep track of the amount of work performed and the type of work performed to develop a given solution. Time tracking doesn't have to be complex: at one customer developers spend less than five minutes a week capturing such information.
Why is Time Tracking Potentially Valuable?
There are several financial issues to be aware of:
Capitalization. For public companies capital expenses (CapEx) can potentially boost book value through the increase in assets (in this case a software-based solution) and increase in net income (due to lower operating expenses that year). On the other hand, operational expenses (OpEx) are accounted for in the year that they occur and thereby reduce net income which in turn reduces your organization's taxes for that year.
Matching. One of the goals of good accounting is to accurately reflect the net income of the enterprise and to prevent income manipulation or "smoothing". As such a key tenet is the principle of matching revenues with the appropriate expenses. For software this means that we expense the cost of the software over the lifetime of the asset against the income at that time. An implication of this is that capitalizing software development, when appropriate, before the software goes into production clearly violates the matching principle since there is no benefit of the asset until such time.
Tax Credits. In some countries you can even get tax credits for forms of software development that are research and development (R&D) in nature.
The point is that the way that a software developer's work is accounted for can have a non-trivial impact upon your organization's financial position.
What Do Agilists Think of Time Tracking?
So, I thought I'd run a simple test. Last week on LinkedIn's Agile and Lean Software Development group I ran a poll to see what people thought about time tracking. The poll provided five options (a limitation of LinkedIn Polls) to choose from:
Yes, this is a valuable activity (33% of responses)
Yes, this is a waste of time (39% of responses)
No, but we're thinking about doing so (2% of responses)
No, we've never considered this (18% of responses)
I don't understand what you're asking (5% of responses, one of which was mine so that I could test the poll)
The poll results reveal that we have a long way to go. Of the people inputting their time more of them believed it was a waste of time than understood it to be a valuable activity. When you stop and think about it, the investment of five minutes a week to track your time could potentially save or even earn your organization many hundreds of dollars. Looking at it from a dollar per minute point of view, it could be the highest value activity that a developer performs in a given week.
The discussion that ensued regarding the poll was truly interesting. Although there were several positive postings, and several neutral ones, many more were negative when it came to time tracking. Some comments that stood out for me included:
It's a colossal waste of time unless you're billing a customer by the hour.
We record time spent on new development work (as distinct from other tasks such as bug fixing in legacy code and so on) as this is capitalised as an asset and depreciated.
I think the *most* pointless example was where the managers told us what we should be putting in.
One day we will move past the "just do it" mentality and have some meaningful conversations and the reasons for what we do.
In my experience time tracking is a massive waste... of time. It's a poor substitute for management.
Why do you need to know more than the info available through Sprint Backlog, Sprint burndown and the daily standup?
Some of my teams (I am SM for three teams) are skeptical about this. They do not think that keeping track of task hours this way will be any more useful than the daily standup reports. And they do not believe that Management can resist the temptation to use task hours as a measure.
I think that there are several interesting implications from this discussion:
Agilists need to become more enterprise aware. It's clear to be really effective that agile delivery teams need a better understanding of the bigger picture, including mundane things such as tax implications of what they're doing. In Disciplined Agile Delivery (DAD) this is something that we refer to as being enterprise aware. There's far more to enterprise awareness than understanding pertinent accounting principles, for interest disciplined agile teams work towards a common technology roadmap and common business roadmap, but appreciating why time tracking is a potentially valuable activity would be a good start.
Management needs to communicate better. It's also clear that management needs to communicate more effectively regarding why they're asking people to track their time. To be fair, management themselves might not be aware of the tax implications themselves so may not be making effective use of the time data they're asking for.
Management needs to govern more effectively. Several people were clearly concerned about how management was going to use the time data (by definition they are measures) which could be a symptom of both poor communication as well as poor governance (unfortunately many developers have experiences where measures have been used against them, a failure of governance, and no longer trust their management teams to do the right thing as a result).
Time tracking should be streamlined. It was obvious from the conversation that several people worked in organizations where the time tracking effort had gotten completely out of hand. Spending 5 minutes a week is ok, and to be quite blunt should be more than sufficient, but spending fifteen minutes or more a day doing so is far too much. Over the years I've helped organizations design measurement programs and I've seen a lot of well-intention efforts become incredibly onerous and expensive for the people they were inflicted upon. I suspect it's time for a reality check in some of these organizations people were alluding to. A good heuristic is that for any measurement you should be able to indicate the real cost of collecting it, the use(s) that the information is being put to, and the value resulting from those uses. If you can't quickly and coherently do that then you need to take a hard look at why you continue to collect that metric. The lament "we might need it one day" is a symptom that you're wasting time and money.
Agile rhetoric is getting in the way. Some of the team-focused agile practices, such as burndown charts (or better yet ranged burndown charts) and stand up meetings may be preventing people from becoming enterprise aware because they believe that all of their management needs are being met by them.
You may be missing out on the benefits of time tracking. Many organizations are potentially leaving money on the table by not being aware of the implications of how to expense software development.
Disciplined agilists are enterprise aware. This is important for two reasons: First, you want to optimize your organizational whole instead of sub-optimize on project-related efforts; second, you can completely miss opportunities to add real value for your organization. In the anecdote I provided it was clear that many agile developers believe that an activity such as time tracking is a waste when that clearly doesn't have to be the case. Worse yet, although someone brought up the issues around capitalizing software development expenses early in the conversation a group of very smart and very experienced people still missed this easy opportunity to see how they could add value to their organization.
Granted, time tracking on an agile project team is nowhere near as sexy as topics such as continuous integration (CI), TDD, the definition of done, continous architecture, or many more. But you know what? Although it's a mind-numbingly mundane issue it is still an important one. 'Nuff said (I hope).

An imporant step in scaling your agile strategy is to adopt a Disciplined Agile Delivery (DAD)
approach instead of one which is just focused on agile construction. One aspect of adopting a DAD approach it to mature your focus from just producing software to instead providing a solution which meets the needs of its stakeholders within the appropriate economic, cultural, and technical constraints. The fundamental observation is that as IT professionals we do far more than just develop software. Yes, this is clearly important, but in addressing the needs of our stakeholders we will often:
Provide new or upgraded hardware
Change the business/operational processes which stakeholders follow
Change the organizational structure in which our stakeholders work
Update supporting documentation
And yes, develop high-quality software
Although delivery of high-quality, working software is important it is even more important that we deliver high-quality working solutions to our stakeholders. Minimally IT professionals should have the skills and desire to produce good software, but what they really need are the skills and desire to provide good solutions. We need strong technical skills, but we also need strong "soft skills" such as user interface design and process design to name just two.
The shift to a solution-oriented focus from a software-oriented focus requires your agile teams to address some of the software-oriented prejudices which crept into the Agile Manifesto
. The people who wrote the manifesto (which I fully endorse) were for the most part software developers, consultants, and in many cases both. It is little wonder that this group would allow a bias towards software development creep into the language of their manifesto.
I recently recorded an audio podcast
about Collaborative Development and Operations (DevOps) and how it relates to Disciplined Agile Delivery (DAD)
. The podcast is 17 minutes long and covers a range of topics including:
- What are the challenges typically faced by Disciplined Agile Development teams as they begin to transition their working solutions into production?
- How best could this gap between Development and Operations be closed so that they worked collaboratively rather than in silos?
- If this DevOps gap was decreased or even closed, what would the measurable value be to Agile projects and their business stakeholders?

A recurring discussion that I have with experienced agile developers is what it means to take a disciplined agile approach. The conversation usually starts off by some saying "but it already requires discipline to do agile", something that I fully agree with, followed by "therefore 'disciplined agile' is merely a marketing term", something which I don't agree with. The challenge with the "standard" agile discipline is that it is often focused on construction activities within a single project team, clearly important but also clearly not the full picture. There's more to an agile project than construction, and there's more to most IT departments than a single development project. In short, there are many opportunities for IT professionals to up their discipline, and thereby up their effectiveness, opportunities which we make explicit in the Disciplined Agile Delivery (DAD) framework.
Let's explore the many aspects to taking a disciplined agile approach:
You adopt "standard" agile discipline
. Aspects of agile which require discipline
include adopting practices such as test-driven development (TDD), active stakeholder participation, working collaboratively, shortening the feedback cycle
, and many more. These strategies are a great start to becoming disciplined IT professionals.
You take a goal-driven approach
. When we first started working on the DAD framework I didn't want to create yet another prescriptive framework, particularly given Rational's track record with the Rational Unified Process (RUP) framework. Rational has been pilloried for years for the prescriptive nature of RUP, which is unfortunate because there are a lot of great ideas in RUP that agile teams can benefit from, some of which we adopted in DAD and many of which are being actively reinvented with the agile community even as you read this. Furthermore, there are many prescriptive elements of the Scrum method that can get teams in trouble. For example, Scrum prescribes that you hold a daily stand up meeting, often called a Scrum meeting, where everyone should answer three questions. That's a great approach for teams new to agile, but it proves problematic in many situations due to it's prescriptive nature. Do you really need to do this once a day? I've been on teams where we held coordination meetings twice a day and others only once a week. Do you really need to stand up? I've been on geographically distrubited agile teams where many of us were sitting down during coordination calls. Do you really need to answer three questions, two of which are clearly focused on status regardless of claims otherwise? I've been on lean teams where we met around our Kanban board and focused on potential blockers. The answers to these questions depends on the context of the situation you find yourself in. The challenge, at least from the point of view of a process framework, is how do you avoid falling into the trap of being overly prescriptive. The strategy we adopted in DAD is to take a goal-driven approach. The observation is that regardless of the situation you find yourself in there are common goals your team will need to fulfill. For example, at the beginning of a project common goals include developing an initial plan, initially exploring the scope, initially identifying a technical strategy, and securing initial funding (amongst others). Throughout construction you should coordinate your activities, improve the quality of your ecosystem, and produce a potentially consumable solution on a regular basis (more on this below). So, instead of prescribing a daily stand up meeting the DAD framework instead indicates you should coordinate your activities, and gives several options for doing so (one of which is a Scrum meeting). More importantly DAD describes the advantages and disadvantages of your options so that you can make the choice that's best suited for the situation your team finds itself in (see this blog posting
for a detailed example of the types of tables included in the DAD book to help you through such process tailoring decisions). In short, our experience is that it requires discipline to take a goal driven approach
to agile delivery over the prescriptive strategies in other agile processes.
You take a context-driven approach
. There are many tailoring factors, which I describe in the Software Development Context Framework (SDCF)
, which you need to consider when making process, tooling, and team structure decisions. For example, a large team will adopt a different collection of practices and tools than a small team. A geographically distributed team will adopt a different strategy than a team that is co-located. You get the idea. Other tailoring factors include compliance, team culture, organization culture, technical complexity, domain complexity, and project type. It requires discipline to recognize the context of the situation you find yourself in and then act accordingly.
You deliver potentially consumable solutions
. One of the observations that we made early in the development of the DAD framework was that disciplined agile teams produce potentially consumable solutions, not just potentially shippable software. Although delivery of high-quality, working software is important it is even more important that we deliver high-quality working solutions to our stakeholders. For example, not only are we writing software but we may also be updating the hardware on which it runs, writing supporting documentation, evolving the business processes around the usage of the system, and even evolving the organizational structure of the people working with the system. In other words, disciplined agilists focus on solutions over software
. Furthermore, "potentially shippable" isn't sufficient: not only should it be shippable but it should also be usable and should be something people want to use. In other words it should be consumable (a concept DAD adopted from IBM's Outside In Development
). Minimally IT professionals should have the skills and desire to produce good software, but what they really need are the skills and desire to provide good solutions. We need strong technical skills, but we also need strong "
such as user interface design and process design to name just two.
The incremental delivery of potentially consumable solutions on an incremental basis requires discipline
to do successfully. DAD teams focus on repeatable results not repeatable processes
You are enterprise aware
. Whether you like it or not, as you adopt agile you will constrained by the organizational ecosystem, and you will need to act accordingly. It takes discipline to work with enterprise professionals such as enterprise architects, data admistrators, portfolio managers, or IT governance people who may not be completely agile yet, and have the patience to help them. It takes discipline to work with your operations and support staff in a DevOps
manner throughout the lifecycle, particularly when they may not be motivated to do so. It requires discipline to accept and potentially enhance existing corporate development conventions (programming guidelines, data guidelines, UI guidelines, ...). It requires discipline to accept that your organization has an existing technology roadmap that you should be leveraging, building out, and in some cases improving as you go. In short, enterprise awareness requires a level of discipline
not typically seen on many agile teams.
You adopt a full delivery lifecycle
. Empirically it is very easy to observe that at the beginning of an agile project there are some activities that you need to perform to initiate the project. Similarly at the end of the project there are activities that you need to perform to release the solution into production or the marketplace. The DAD process framework addresses the effort required for the full delivery effort, including project initiation, construction, and deployment. Our experience is that it requires discipline on the part of IT professionals to include explicit phases
for Inception/Initation, Construction, and Transition/Deployment and more importantly to focus the appropriate amount of effort on each. One danger of explicit phases is that you run the risk of taking what's known as a Water-Scrum-Fall
approach, a term coined by Dave West the person who wrote the forward for the DAD book, where you take an overly heavy/traditional approach to inception and transition in combination with a lighter agile approach to construction. Water-Scrum-Fall occurs because many organizations haven't made a full transition to agile, often because they think it's only applicable to construction. Our experience is that you can be very agile in your approach to inception and transition, experience we've built into the DAD framework. Having said that it clearly requires discipline to keep inception activities short
and similarly it requires discipline to reduce the "transition phase" to an activity
You adopt a wider range of roles
. An interesting side effect of adopting a full delivery lifecycle is that you also need to adopt a more robust set of roles. For example, the Scrum method suggests three roles - Scrum Master, Product Owner, and Team Member - a reflection of the Scrum lifecycle's construction focus. DAD suggests three primary roles - Team Lead, Product Owner, Team Member, Architecture Owner
, and Stakeholder - as well as five secondary roles which may appear at scale.
You embrace agile governance
. Governance establishes chains of responsibility, authority and communication in support of the overall enterprise’s goals and strategy. It also establishes measurements, policies, standards and control mechanisms to enable people to carry out their roles and responsibilities effectively. You do this by balancing risk versus return on investment (ROI), setting in place effective processes and practices, defining the direction and goals for the department, and defining the roles that people play with and within the department. It requires discipline to adopt an agile approach to governance
, and that's something built right into the DAD framework.
