Presentation: "Sustainable Design for Agile Teams"

Time: Friday 10:10 - 11:10

Location: Stanford

Abstract: Too many teams interpret "Agile" as a permit to not think about design. But if they have ambitious goals, Agile teams need more than standup meetings and iterations. Many teams get off to a quick start, building lots of features in early iterations, but end up with a "Big Ball of Mud". Without clear and well-structured code, they cannot sustain their pace and also put themselves at risk of, one day, encountering a critical feature they simply cannot deliver. Without the common understanding between developers and stakeholders that is forged in domain analysis, one of the greatest benefits of iteration, the deepening communication about what the software should do and how it should do it, is never realized.

We don't want to return to the "Analysis Paralysis" that we used to endure (and that many teams still do), but interpreting "Do the Simplest Thing" as "Do the Easiest Thing" doesn't work either.

This talk will consider ways of incorporating modeling and design into the iterative process in a lightweight way that increases communication with stakeholders and decreases the likelihood of painting ourselves into corners, without returning to the dead-hand of the analysis phase. As a concrete example of how such techniques can be incorporated into the Agile framework, we'll have an overview of a simple process Domain Language has used with its clients for the last six years. The right kind of modeling and design, far from bogging down a project, leads to a livelier and more sustainable development pace.

 Eric  Evans

Eric Evans is a specialist in domain modeling and design in large business systems. Since the early 1990s, he has worked on many projects developing large business systems with objects and has been deeply involved in applying Agile processes on real projects.

Out of this range of experiences emerged the synthesis of principles and techniques shared in the book "Domain-Driven Design," Addison-Wesley 2003.

Eric now leads Domain Language, Inc., a consulting group which coaches and trains teams to make their development more productive and relevant through effective application of domain modeling and design.
