Ok now onto some of the questions that were submitted but I didn’t time to answer during the webcast. I’ve divided them into sections based on the type of question so you can easily scan down to topics you’re interested in:
Alternative approaches to managing requirements
Q. What's the advantage of a requirements management tool if I could link my change management tickets to fine grained requirements (use cases, storyboards) that are maintained on a wiki or other collaboration tool (e.g. Sharepoint or IBM Connections)? It would seem that the work items would give you the needed traceability and metrics?
A. While you might be able to create the level of traceability you require, how would you report on it? Would you have to build bespoke views and reports? And would the use of a wiki for ‘fine grained requirements’ provide you with a view of requirements in context with one another as opposed to individual wiki pages? Where would you document additional properties of requirements? Could you easily reuse requirements across projects? A requirements management tool like IBM Rational DOORS Next Generation provides built-in traceability views and reports, enables to you to structure requirements in context with another in document-like views, provides user-defined properties for recording additional information and facilitates reuse of requirements.
Requirements Management and Agile Development
Q. We are mostly using water fall model, but looking into checking if Agile works for our customers. I am very interested in the role of a Requirements Analyst in the Agile world. In our world, the analyst is a facilitator of requirements gathering and not a SME on the business application we are gathering requirements for.
A. That facilitation role and the analysis skills of the Requirements or Business Analyst are still essential in Agile development. A common mistake when moving to moving to more agile approaches is appointing a ‘Product Owner’, who is a subject matter expert in the business domain you are building an application or product for, and expecting them to write the requirements or ‘user stories’. While they are experts in the business and you need that expertise on hand for Agile to work, they are not usually skilled in getting to the root goals or needs of the business problems you’re looking to address with the product or application. Without the skills of the Requirements or Business Analyst, it’s all too easy for the user stories to become about automating the way things are done today rather than addressing the real business issues in an optimal way. You can read more about the role of the analyst in Agile development in an interview with Mary Gorman of EBG Consulting.
Q. How does the IBM requirements toolset compare to more "agile" focused toolsets like Atlassian, Rally, etc.?
A. IBM is very committed to supporting agile development, particularly when agile is scaled to large, distributed development teams. At the heart of our agile development capabilities is Rational Team Concert which supports agile planning, task management and change management. As stated in the webcast though, we’ve found in our own continuous delivery process and heard from clients, that a place is needed to capture more details of requirements and their associated properties, in context with one another, together with supporting artifacts like storyboards, workflow scenarios and use cases. The integration of Rational Team Concert with Rational DOORS Next Generation provides those additional capabilities while preserving traceability to user stories and epics managed in the product backlog.
IBM Requirements Management solutions
Q. It seems this discussion is on Rational DOORS. Is Rational Requisite Pro still offered? If so then how do these two products compare?
A. IBM continues to support, maintain and respond to enhancement requests for Requisite Pro, but our future direction for requirements management for IT application development lies with Rational Requirements Composer and we provide migration support and a trade-up program. Please contact your IBM representative for more details. If you are using Requisite Pro for requirements management for complex products or embedded systems development, then you might also want to look at whether Rational DOORS or Rational DOORS Next Generation is the right move forward for your organization. But don’t worry we’re not forcing you to migrate today.
Q. You've mentioned DOORS Next Generation in your presentation, what is that? Does it replace DOORS?
A. IBM Rational DOORS Next Generation is a requirements management application on a collaborative lifecycle management platform for systems and software engineering that provides requirements collaboration, planning, reuse and lifecycle traceability. DOORS Next Generation (DOORS NG) was introduced in 2012 to take advantage of the common, collaborative ‘Jazz’ platform shared by Rational Team Concert, Rational Quality Manager, Rational Design Manager and Rational Requirements Composer; and to extend the requirements management capabilities in Requirements Composer to meet the needs of product & systems development organizations developing complex and/or embedded systems. DOORS NG will enable IBM to introduce new capabilities, faster, that would have been more difficult to deliver with existing DOORS product. However DOORS NG does not replace DOORS today. We have a very large install base of DOORS users working on programs that can last tens of years, and we will continue to support, maintain and enhance the DOORS 9.x series to meet the needs of those users. We encourage existing DOORS users to take a look at DOORS NG, to try it out on pilot projects and use the interoperability capabilities to exchange and/or link data with DOORS 9.x. Existing DOORS customers with active support & subscription are entitled to use DOORS NG without requiring an additional purchase – you can use your existing DOORS license entitlements to use with either DOORS or DOORS NG or a combination of the two. But we are not telling existing DOORS users to migrate live projects to DOORS NG today. DOORS NG in it’s early releases is attractive to organizations who don’t currently use a requirements management tool and are looking for a web based solution that also offers common platform integration with change management, agile planning, test management and design management capabilities. You can download a trial and follow development plans for DOORS NG on Jazz.net.
Q. How does Rational DOORS Next Generation compare to Rational Requirements Composer?
A. DOORS Next Generation is based on Rational Requirements Composer but extended to meet the requirements management needs of product & systems development organizations developing complex and/or embedded systems. In the first releases of DOORS NG, the web client is identical to Requirements Composer, but DOORS NG also features a rich client which is designed for usability of editing large requirements specifications. The strategy for the two products is that while Requirements Composer will be focused on the needs of business analysis and IT application development teams, DOORS NG will be focused on the needs of systems engineers and product & systems development teams.
I’d like to wrap up this post by thanking all of you who attended the webcast, participated in the polls, asked some great questions and completed the survey feedback. If you missed it, you can catch a replay or download the slides. I’d welcome any additional comments or questions here.
