When it comes to testing on agile projects it is common practice for agile teams to adopt a "whole team testing
" approach where the team itself does its own testing. To accomplish this agile teams will often embed testers in the development team. Programmers will work closely with the testers, often via non-solo development
strategies such as pair programming, to pick up their valuable testing skills. The testers will in turn pick up new skills from the programmers, and in effect both groups will move away from being just specialists (testers or programmers) to being what's called generalizing specialists
. Whole team testing can be very different from traditional approaches where programmers may do some testing, often unit testing of their own code, and then throw it over the wall to testers and quality assurance (QA) professionals for verification and validation.
The types of testing that the parallel independent test team performs may include:
Pre-production system integration testing. Does the solution work within your overall organizational ecosystem? Importantly, if this is one of several teams currently developing new solutions, does this team's solution work with what will be in production (including the work in progress of other teams) when they go to release? In mid-to-large organizations the only economical way to do this sort of testing is via an independent, centralized team.
. Although it's possible to do usability testing on the development team, the reality is that usability testing is a specialized skill that few people have (although could pick up via non-solo development). Furthermore, particularly for solutions with many potential users, you may want to invest in a usability testing
lab. This is a centralized resource, or an outsourced resource these days, which is shared across many teams.
. Security testing is also a specialized skill, albeit one well supported with sophisticated security testing tools such as the Rational Appscan
suite which can be included in your continuous integration (CI) strategy. Many organizations will centralize their security testing efforts.
Exploratory testing. The fundamental goal of exploratory testing is to discover where the solution breaks, as opposed to confirmatory testing which focuses on showing that the solution conforms to the requirements (this is the type of testing the development team typically focuses on). Exploratory testing is also a skill, a good one which everyone should strive to pick up, but exploratory testers are often few in number in many organizations. So, to leverage their skills effectively you may want to have some of them on the independent test team while they mentor others while doing so.
Non-functional testing. Non-functional requirements have a tendency to fall through the cracks on some development teams. Knowing this the independent test team will often "test to the risk" and focus on non-functional issues.
And much more. The above points are just exemplars, not an exact list. Please follow some of the links above for greater detail.
I'd like to leave you with several important thoughts:
The developers still do the majority of the testing. Just because there's an independent test team it doesn't imply that they are the ones doing all the testing. In fact, nothing could be further from the truth. They should be doing the minority of the testing effort, albeit the more difficult forms of it.
An independent test team will support multiple dev teams. For example, a test team of 5-6 people could support several development teams totalling 70 to 80 people. I typically look for a 15:1 or 20:1 ratio of developers to independent testers, hopefully even higher than that.
- You need to consider better tooling. Although the development team will still be using common agile testing tools such as the xUnit and FIT frameworks the independent test team (ITT) will need more sophisticated tooling. First, the ITT will need to be able to report defects back to the team easily. When the development team is using a Jazz-based tool such as Rational Team Concert (RTC) then this can easily be done using either RTC (the web interface may be sufficient) or another Jazz-enabled product such as Rational Quality Manager (RQM). Second, the ITT will likely need more sophisticated testing tools, such as Rational Appscan for static and dynamic security testing and Rational Performance Tester (RPT) for performance testing (just two of several software quality management tools you should consider).
Independent testing is economical. Although I listed several tools in my previous point (hey, I do work for a vendor after all) an "unfortunate" implication of my advice (unfortunate for IBM at least) is that you can reduce the number of licenses that you require and still get this critical testing done by centralizing their use.
It may be a bit more complicated in regulatory environments. In a strict regulatory environment the independent test team may need to repeat, or at least validate, the testing efforts of the development team. In regulatory environments my fundamental advice is always this -- Have practical people, including yourself, read and interpret the regulations. If you leave it to the bureaucrats you'll get a bureaucratic solution.
This is an important scaling technique. Parallel independent testing, when done in an agile manner, is an important technique which you should consider when scaling agile strategies to meet the uniques needs of the situation that you find yourself in.

IBM Rational recently published an update to my Agility@Scale e-book, which can be downloaded free of charge. The e-book is a 21 page, 2.3 meg PDF (sorry about the size, guess the graphics did it) . It overviews the Agile Scaling Model (ASM) (which has since been replaced by the Software Development Context Framework (SDCF) ), Disciplined Agile Delivery (DAD), the scaling factors of agility at scale, and ends with some advice for becoming as agile as you can be. In short it's a light-weight coverage of some of the things I've been writing about in this blog the past couple of years. Could be a good thing to share with the decision makers in your organization if they're considering adoption agile strategies.
There is a fair bit of rhetoric surrounding agile methods, some of which we subscribe to and some of which we don’t. We’d like to briefly examine the rhetoric which we’ve found to be the most misleading for people trying to be effective at adopting agile techniques. The following list is in the format X but Y, where X is the rhetoric and Y is the strategy promoted by the Disciplined Agile Delivery (DAD) process framework. This includes:
- Requirements evolve throughout the lifecycle BUT the scope should still be agreed to at the beginning of the project. There has to be an initial vision for a project, a vision which your stakeholders should help define and then agree to, and to come to that vision you will need to perform some initial requirements envisioning. A list of high level features is part of this initial vision. Yes, the details are very likely to evolve over time but the fundamental goals of your project and scope of your effort needs to be defined early in your project. In a very small minority of situations you may not be able to get the right people together, either physically or virtually, to define the initial vision – this should be seen as a significant project risk.
- Simple designs are best BUT the architecture should be thought out early in the lifecycle. Too many developers interpret the advice to focus on simple designs to mean that they should build everything from scratch. Yet more often than not the simplest design is to take advantage of what is already there, and the best way to do that is to work closely with people who understand your existing technical infrastructure. Investing in a little bit of architectural envisioning early in the lifecycle enables your team to identify existing enterprise assets that you can leverage, to identify your architectural options, and to select what appears to be the best option available to you. The details will still emerge over time, and some decisions will be deferred until a later date when it’s more appropriate to make them, but the bottom line is that disciplined agilists think before they act.
- Teams should be self organizing BUT they are still constrained (and enhanced) by your organizational ecosystem. Intellectual workers, including IT professionals, are most effective when they have a say in what work they do and how they do it. IT professionals can improve their productivity by following common conventions, leveraging and building out a common “dev-ops” infrastructure, building towards a common vision, and by working to common business and technical visions. In short, disciplined agile professionals are "enterprise aware".
- Delivery teams don’t need prescriptive process definitions BUT they do need some high-level guidance to help organize their work. Individual IT professionals are typically highly-skilled and highly-educated people often with years of experience, and teams of such people clearly have a wide range of knowledge. As a result of this knowledge it is incredibly rare for such people to read detailed procedures for how to do their work. However, they often still require some high-level advice to help them to organize their work effectively. Teams can often benefit from techniques and patterns used by other teams and this knowledge sharing should be encouraged.
- IT professionals know what to do BUT they’re still not process experts. A decade ago the strategy was to provide detailed process advice to teams, but recently the pendulum has swung the other way to provide little or no defined process at all. Over the last few years there’s been a trend within the agile community to advise teams to define their own process so that it’s tailored to their own unique situation. While this clearly strokes people’s egos, it’s relatively poor advice for several reasons. First, although every team is in a unique situation there is significant commonality so having at least a high-level process framework from which to start makes sense. Second, although these teams have a wide range of knowledge it might not be complete, nor consistent, nor is it clear what the trade-offs are of combining all the really good techniques that people know about. There is significant benefit in having a flexible process framework such as DAD which shows how everything fits together.
- IT professionals should validate their own work to the best of their ability BUT they likely aren’t testing experts so therefore need help picking up the appropriate skills. The mantra in the agile community is to test often and test early, and better yet to test first. As a result agile teams have adopted a “whole team” approach where the development team does its own testing. This works when there are people on the team with sufficient testing skills and more importantly can transfer those skills to others. Minimally you will need to embed testers into your delivery teams, but you should also consider explicit training and mentoring of everyone on the team in testing and quality skills. You may find my agile testing and quality strategies article to be an interesting read.
- Disciplined agile teams work in an iterative manner BUT still follow a lifecycle which is serial over time. On any given day people on a DAD project team may be performing analysis, testing, design, programming, deployment, or a myriad of other activities and iterating back and forth between them. But, the DAD lifecycle includes three distinct phases which are performed in order. So, DAD is both iterative in the small but serial in the large.
There is a distinct rhythm, or cadence, at different levels of the agile process. We call this the agile 3C rhythm, for coordinate, collaborate, and conclude (which is sometimes called stabilize). The agile 3C rhythm occurs at three levels in Disciplined Agile Delivery (DAD):
- Day. A typical day begins with a short coordination meeting, called a Scrum meeting in the Scrum method. After the daily coordination meeting the team collaborates throughout most of the day to perform their work. The day concludes with a working build, hopefully you had several working builds throughout the day, which depending on your situation may require a bit of stabilization work to achieve.
- Iteration. DAD construction iterations begin with an iteration planning session (coordinate) where the team identifies a detailed task list of what needs to be done that iteration. Note that iteration modeling is often part of this effort. Throughout the iteration they collaborate to perform the implementation work. They conclude the iteration by producing a potentially consumable solution, a demo of that solution to key stakeholders, and a retrospective to identify potential improvements in the way that they work.
- Release. The DAD lifecycle calls out three explicit phases - Inception, Construction, and Transition – which map directly to coordinate, collaborate, and conclude respectfully.
The agile 3C rhythm is similar conceptually to Deming’s Plan, Do, Check, Act (PDCA) cycle:
- Coordinate maps to plan
- Collaborate maps to do
- Conclude maps to check and act
I'm happy to announce that a revised version of the Lean Development Governance
white paper which I co-wrote with Per Kroll is now available. This version of the paper reflects our learnings over the past few years helping organizations to improve their governance strategies.
There's a more detailed description of the paper here
I'm happy to announce that IBM Rational's RP252 Advanced Disciplined Agile Delivery (DAD) workshop
is now available. This is a 3-day, hands-on workshop which teaches students the fundamentals of Disciplined Agile Delivery (DAD)
. This workshop is offered both publicly and privately.
For some reason, it seems as if everyone's grandfather at one point in time recommended to use the right tools for the job. That's practical wisdom from my point of view, one that is certainly an issue for agile development.
One of the primary messages, I hope, of the Agile Scaling Model (ASM)
is that context counts. Although the focus of the ASM is on describing a contextual framework for tailoring your process to meet the needs of the situation that you find yourself in, it's also applicable to your tooling selection. For example, the tool choices of a co-located team will be much different than that of a geographically distributed team. A co-located team will likely use a whiteboard
or paper for their agile modeling
efforts, whereas distributed team members may need to capture their diagrams using a more sophisticated tool such as Rational Requirements Composer (RRC)
so that their work can be shared electronically. Having said that, RRC would be overkill for a co-located team (unless they had regulatory compliance issues). Different teams, different situations, therefore different tooling choices.
One of the concerns that I run into from customers is that some of our legacy products don't support agile very well. Once again, it's a matter of context because many of our legacy products reflect the realities faced by more traditional teams. The challenge occurs when you try to take a legacy product which is well suited for traditional development, such as Rational ClearCase
, and try to apply it on agile projects. Although ClearCase makes sense in certain scaling situations, particularly very large teams that are geographically distributed, you'd be better advised to use something like Rational Team Concert (RTC)
for configuration management on most agile teams (note that RTC does far more than just SCM).
So, if you're taking an agile approach you should consider Rational tools such as RTC, RRC, Rational BuildForge
, Rational AppScan
, and others which support agile
development. Granted, some you would only use at scale -- for example Buildforge is a good option in really complex environments, but if you don't face that complexity then you'll likely find that RTC's build engine is sufficient. Similarly, if you're taking a traditional approach to development then you'll likely consider products such as ClearCase, Appscan, RTC, and Rational Software Architect (RSA)
instead. Different situations, different tooling choices.
What's even more confusing is that some products support a range of process paradigms. For example, RTC supports agile, lean, iterative, and traditional approaches to development. The same can be said of Appscan and several other products. Notice how I listed RTC and Appscan for both agile and traditional development above.
So, if anyone tells you that Rational tools don't support agile development don't believe them. Ask them which tools that they're talking about, and ask them if they're aware of the Rational products that do support agile development. Context counts.
I'm happy to announce that I've accepted the role of Managing Director of the Scrum Alliance
(SA), a part-time position in addition to my duties here at IBM. On the surface this must appear to be a radical and unpredictable departure for me, considering my history of being critical when it comes to some of the past activities of the Scrum Alliance. To be fair, I've actually been critical of the Certified Scrum Master (CSM) scheme
, and rightfully so. But I have also actively embraced the good ideas contained in Scrum and have incorporated them, with attribution, in my writings about Disciplined Agile Delivery (DAD)
and other agile topics. I believe that I've made this very apparent in this blog and in other sources such as the Agile Modeling
site. So, it really isn't such a radical departure for me afterall, although still arguably one that was difficult to predict. In fact, one of the reasons why the Scrum Alliance approached me to be Managing Director is the fact that I have been critical of many of the Scrum community's behaviors.
So, over the next few months you're going to see what I believe to be some welcome changes at the Scrum Alliance. Our first step at serving you better will be to apply agile strategies and principles in the way that we work. Importantly, we'll be taking a three pronged strategy based on respect, clarity, and integrity. We have dubbed this strategy "Scrum Alliance 2.0".
To be more respectful of existing and potential SA members, we will begin executing the following activities:
- Adopt respectful language on the site. We've begun a review of the SA web site to identify potentially disrespectful language. For example, on the About page we indicate that Scrum trainers pay for your first two years of SA membership fees. Who do we think we're kidding? Those fees are clearly coming out of the money that you paid to take the training and we shouldn't hide this fact. I believe that our improved clarity strategy, see below, will go a long way to increasing our respectfulness towards others.
- Tone down the rhetoric. There's been a lot of rhetoric espoused over the years regarding Scrum, which is true of many other issues within the IT industry and not just Scrum. From now on any rhetoric that we do promote we're going to actually live by. For example, not only are we going to claim that Scrum increases visibility (which it can in fact do) we're going to be an examplar of that by being open ourselves. More on this below.
- Deprecate the chicken and pig analogy. Calling people chickens and pigs may be fun at first, and to be fair the analogy helps to cut through some of the politics surrounding many project teams, but the terminology is in fact disrespectful. We can and should do better.
Clarity through openness and honesty
We are also starting to execute on four activities for improving the clarity of how we operate:
- Be crystal clear about what "not-for-profit" actually means. This is a wonderfully deceptive term from the US tax system which can make organizations appear far more virtuous than they actually are, which is particularly easy in situations where the audience doesn't have a sophisticated knowledge of finance. Not that I'm implying anything. Although we have taken some steps to explain the implications of what being a "not-for-profit" organization means, we could do a lot more by being less self-serving. Yes, the SA isn't a for-profit organization. The implication of this being that we need to spend the money we rake in, but it doesn't imply that as individuals we can't make a lot of money via our SA work. I'm not taking on the position of Managing Director for free after all, and I'm sure that previous MDs have found the position lucrative.
- Publish our salaries. To live the high standards which we espouse through our rhetoric, we're going to be very clear about the way that we operate. This includes publishing the salaries of the employees of the SA and the revenue derived from Scrum training of all of our certified trainers. Part of being respectful to our membership is to be clear about how we spend their hard-earned money.
- Publish how we spend the rest of the money. After we pay ourselves, how much do we really spend on supporting user groups, education, and research as we claim? Don't you think you deserve to know? I certainly do, which is why we're going to ensure our finances are no longer opaque. With tens of thousands of members and/or "certified masters" running around out there, it's pretty clear that we making a lot of money. To guarantee that money is being spent appropriately we're going to share with our membership where it's coming from and going to.
- Publish our meeting minutes. This will be both in written form, e.g. traditional meeting minutes, as well as recorded form (ideally video but at least audio). The only way that our membership can be assured that we're working in an ethical and integral manner is through complete visibility into our operations.
The fundamental idea here is that the Scrum Alliance should have nothing to hide from our membership. We've preached open and honest communication for years, now we're going to start actually living by those words. Yes, it may be a bit painful to work to this level of clarity, but we feel that you deserve this.
Integrity through actions, not words
Finally, we're taking three actions to increase the overall integrity of the Scrum community:
- Increase investment in research. Although we've big claims about support Scrum research over the years, very little has actually come of this due to lack of funding (see discussion of salaries above) which can be seen in the serious lack of research results posted at the SA site. Of the six publications at the site tagged as research results, three were performed by Carnigie Mellon University, the home of the Software Engineering Institute, producers of the CMMI. Although I personally respect the work surrounding the CMMI, not that I agree with all of it, I'm concerned about relying on CMU for half of our Scrum research results. We can and should do a lot better, and the first step is to divert some funds away from our own pockets into research. Having actual empirical results, as opposed to espousing rhetoric about empiricism, will go a long way towards more respectful behavior via actual fact-based discussions. Until then, you may find my IT Survey Results page to be a valuable resource.
- Deprecate the Certified ScrumMaster (CSM) certification. Although I would prefer to end this embarrassment immediately, we need to be respectful of the fact that CSM courses have been scheduled several months in advance and some people have already paid for seats in them. So, as of June 30th 2011 the CSM certification will be deprecated. This should give our Certified Scrum Trainers time to rework their business models and focus on more respectable activities.
- Existing CSMs must clarify the certification. People who have previously "earned" the CSM designation will be grandfathered in until December 21st, 2012 in accordance with the Mayan Calendar. However, until that time all CSMs who choose to indicate their designation publicly (many CSMs choose not to) in email signatures, business cards and so on must now use the following wording - "Certified ScrumMaster (earned by staying awake during a two/three day training course)". This wording reflects our new desire for clear and open communication as well as for being respectful. Far too many people are fooled by the terms "certified" and "master" and we're going to do our best to reduce this problem through greater clarity.
As I hope you have guessed by now this blog is an April Fool's joke
. I have no intention of becoming the Managing Director of the Scrum Alliance and my condolences go out to anyone who would take on this position. This blog posting does however reflect what I would do to bring greater clarity, integrity, and respect to the Scrum community. The Scrum Alliance can and should choose to do a lot better. I hope it has been food for thought.
I recently did the voice over for our Rational.Everyware Agility@Scale whiteboard video
, which is a bit less than 4 minutes in length. As I narrate a whiteboard sketch evolves, sometimes using sticky-notes and index cards, to help explain what I'm talking about.
In the video, I describe:
- The history of agile
- Some of the challenges surrounding traditional development
- Some of the basics of agile, such as increased collaboration with stakeholders and on delivery of consumable solutions
- The benefits of agile, including increased quality, time to value, stakeholder satisfaction, and ROI
- Domains where agile is being applied successfully
- What IBM agility@scale is all about
- How some of the scaling factors change the way that you'll work and approach tooling
- Rational Team Concert (RTC), what it is and why you'd be interested in it
- Benefits that customers are seeing with RTC
- How you can download a fully-functional version of RTC for a team of up to 10, with no time limit, free of charge
So, it's basically a cool marketing video for a bunch of free stuff.
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.
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?
On a related note, IBM's Collaborative Development and Operations
landing page has some great resources if you're interested in how to implement.
During the second week of August the Agile 2011 conference was held in Salt Lake City (SLC). As you likely know the Agile Manifesto was formulated 10 years ago in SLC so it was apropos to hold it there. There was some excitement around the 10 year anniversary of the manifesto, with a panel session with the 17 authors of it. Sadly there seemed to be little excitement around the efforts of the 10th anniversay agile workshop
in February which proposed a potential path forward for the agile community. I found the conference to be an evolutionary improvement over the conferences of the past few years, which is a very good thing because the focus since 2008 has moved beyond the "cool" new programming techniques to include the issues that enterprises face.
Starting at the Agile 2008 conference I've seen an uptick in interest in what I would consider some of the more mature topics in agile development, although I'm unfortunately still seeing significant confusion out there too, in part due to over-exuberence of people new to agile. For example, there's people still asking about basic issues about agile architecture
and agile database
techniques, although I was really happy to see more coherent discussions around scaling agile
. My own presentation about the Agile Scaling Model
was well attended and I suspect I opened a few people's eyes regarding the realities that we face (yes, there's a lot more to it than holding a "scrum of scrums", yeesh). We have a long way to go until people really start to understand scaling issues, but we're clearly on the path to getting there.
The conference show floor was interesting, with a wide range of vendors offering services and products focused on agile and lean. One thing that I noticed was many vendors had large monitors showing off their ability to support lean task boards, which for the most part they all looked the same. At the IBM booth we were showing off some of the Jazz tools
, in particular Rational Team Concert (RTC)
. For a long time now we've been giving away fully functional, with no time limit, licenses of RTC for teams of up to 10 people. Something worth checking out.
The Agile 201x conferences hosted by the Agile Alliance are always a good investment of your time and money, and Agile 2011 was no exception. See you at Agile 2012 in the great state of Texas!
On Nov 16 2011, Kim Werner, Agile Coach from ATSC and Liz Parnell, Solution Design Manager from Blue Cross Blue Shield of North Carolina (BCBSNC), gave a webcast
sharing their experiences regarding how BCBSNC adopted a few Agile techniques, with the help of some good coaching, and adopted some IBM Rational Jazz tools
(Rational Team Concert and Rational Requirements Composer) to reduce time to market and lower development costs. BCBCNC works in the highly-regulated healthcare industry, so faced a few interesting constraints when adopting agile.
A few days later someone asked a series of questions that I thought would make an interesting blog posting, so here goes:How much of IBM's projects (in percentage) are agile at the moment?
I don’t have exact numbers, but I believe that 90%+ of our teams in SWG are applying agile techniques in practical ways that make sense for their projects. The primary goal is to be effective – in frequent releases, higher quality, and happy customers – not just agile. By the way, there is roughly 30,000 developers in SWG.Can all of IBM's projects work with an agile methodology?
It’s certainly possible, but it may not always make sense. Products that are in maintenance mode with few bugs or feature requirements may not benefit as much from agile practices -- those teams will likely continue to do whatever it is that they have been doing. Having said that, it's still highly desirable to apply agile techniques on maintenance projects.
Also, agile methods can be harder to use on some projects than others, for example, around hardware development. As a general rule, I believe that the majority of software projects can benefit from agile techniques. The primary determinant of whether a team can adopt agile techniques is culture and skill – not team size, the domain, or the degree of geographic distribution. That notion surprises many people who think that large agile teams
or geographically distributed agile teams
can’t succeed in adopting agile practices.Are agile projects sub-parts of large waterfall projects?
In some cases, that may happen. I’m sure it’s also true in reverse. We see many customers who are migrating from waterfall projects to a more agile way of doing things, and they often start this migration with smaller sub-projects. At IBM, we have tens of thousands of developers worldwide on hundreds of teams, so we have examples of pretty much any combination of agile, iterative, and traditional practices that you can imagine. There’s definitely not one size that fits all, which is a key aspect of the Disciplined Agile Delivery (DAD)
process framework.What do you think the impact of these numbers will be on the PM community?
The IBM PM community is embracing agile. And the reality is that a majority of development organizations around the world are moving to agile now as well (as much as 80% in some of the recent studies I’ve seen). I look forward to the increased adoption of agile methods by the PM community in general. The fact that PMI now offers an Agile Certified Practitioner training program certainly underscores the fact that agile practices are being adopted widely in the mainstream which is a great thing to see.
In November 2011 Paul Gorans, the Accelerated Solution Delivery (ASD) practice lead in IBM GBS, and I ran an agile adoption survey
. The survey explored a range of issue, including the factors that appear to be associated with the success and failure of agile project teams. Paul wrote up his thoughts in his Agile State of the Art Survey
article on ibm.com and I did the same for Dr Dobb's Journal in Agile Success Factors
. This blog posting summarizes the results of the survey.
Factors which appear to accelerate agile adoption include:
- People are assigned to a single team
- Development teams have easy access to business expertise
- Development teams are organized for agile delivery (not traditional)
- Your organization has an agile support group/community of excellence
- Your organization is explicitly addressing barriers to agility
- There is executive sponsorship for agile
- Agile teams are measured on value creation
- Your organization's IT governance strategy includes an agile path
Factors which appear to decelerate agile adoption include:
- Agile teams are measured using traditional metrics
