Requirements

More accurate requirements: Who framed Roger Rabbit?

Last June at Innovate 2010 in Florida Kurt Bittner envisioned the new role and responsibilities of the next generation business analyst. If you were not able to attend, his presentation is available online so you can check it out: Transforming the role of the Business Analyst. The need for a different role and responsibilities is to provide solutions for ongoing problems a lot of companies are faced with. These are common problems like:

  • Users expecting  functionality they did not initially ask for
  • Users demanding functionality they will never use
  • Contradictory of conflicting requirements

In order to be more successful, a number of changes are to be made and lessons are to be learned. One of them is that business analysts need to be more focused on desired outcomes rather than features. And another is that business analysts need to probe into root causes rather than being satisfied with just identifying the wants. Being focused on outcomes and unraveling root causes can be hard work and sometimes it is easy to mix them up or to get stuck. A smarter way it is to be more aware of the language that is used for questioning and context frames . Read More

Dutch post: Meer heldere requirements: Kies de juiste verpakking

Mijn collega Kurt Bittner heeft afgelopen juni  tijdens IBM Innovate 2010 (Florida) zijn visie gegeven op de nieuwe rol en verantwoordelijkheden van de nieuwe generatie informatieanalisten. Wanneer je geen kans hebt gezien om zijn presentatie bij te wonen, bekijk die dan via Slideshare: Transforming the role of the Business Analyst. Hieronder volgende enkele observaties of veel voorkomende problemen die hebben geleid tot zijn visie:

  • Gebruikers verwachten andere  functionaliteit dan waar ze oorspronkelijk om hebben gevraagd.
  • Gebruikers eisen functionaliteit die ze nooit zullen gebruiken
  • Gebruikers geven tegenstrijdige of conflicterende requirements Read More

Dutch post: Meer heldere requirements: vermomde processen

De laatste paar dagen hebben verschillende mensen mij dezelfde vraag gesteld: “Hoe kunnen we meer heldere requirements krijgen”. Hoewel ik het eens ben dat het niet netjes is om een vraag met een vraag te beantwoorden, is het in mijn visie beter om in dit geval soepel om te gaan met die etiquette. En wel  omdat deze vraag eigenlijk niet zo eenvoudig te beantwoorden is. Bijvoorbeeld, waarom is dit nodig en welk probleem lost het op? Of, wat bedoel je precies met helder? En heb je heldere requirements en wil je er meer? En in dat geval, meer dan wat? Of heb je requirements die niet helder zijn en die je beter wilt kunnen communiceren. En zo ja, hoeveel beter?

Je zou kunnen zeggen dat dit gewoon spelen met woorden is. En dat klopt! Maar is het formuleren en communiceren van requirements niet feitelijk hetzelfde? Voor meer heldere requirements zijn een tal van zaken benodigd. Er is echter een belangrijk element dat vaak over het hoofd wordt gezien, namelijk inzicht in de structuur van taal en de wijze waarop taal wordt geïnterpreteerd. Read More

The Kernel Journals 7: SatNav for Software Development Projects

In the last Kernel Journal we looked at the problem that Barry Boehm was aiming to solve back in 1995 when he first proposed his three standard process milestones (which later gained industry prominence as the milestones in the Unified Software Development Process and the Rational Unified Process), namely that “the proliferation of software process models provides flexibility”, but leaves us “with no common anchor points around which to plan and control.” [Barry Boehm, November 1995]. We looked at how a small set of domain entities with simple state progression models (which we call “Alphas”) can make these common anchor points much more practical and useful while ensuring that they remain process-neutral and do not become “document-driven”.

The alphas, when used with common milestones such as the Unified Process Milestones, can actually give us much more than this – they can provide a project status and health dashboard that can be used by the customer and supplier organizations to assess the current status and health of any / all projects, irrespective of which processes or practices they are following. The graphic below shows just such a dashboard, with a set of kernel alphas and a traffic-light status for each alpha, which is derived by comparing where the project is now (the state machine to the left of each traffic light) with where it needs to be to achieve the next project milestone (the state machine to the right of each traffic light).The Kernel Journals 7: SatNav for Software Development Projects

In Kernel Journal 5: “Making the Invisible Visible” I described how we can easily “skin” a process kernel, by providing a portal for projects to capture, share and agree the essential project information that is needed to achieve each state progression (for example, using a set of templated Wiki pages). Once we have done this, we can make the alpha dashboard much more useful to the project teams themselves, by flagging which sections of the project portal need to be updated and agreed to get the project to where it needs to go next.

This gives us the equivalent of a Satellite Navigation System for our software projects project that enables us to:

  • Set our journey destination and waypoints (milestones)
  • Track where we are now, compared to where we want to be
  • Get guidance on what to do next in order to progress towards our destination.
