Agile Development Practices 2009

If XP and Scrum are the first generation of agile methods, Kanban software development is the next generation. Kanban integrates lean and agile principles to create better software faster and at less cost. Kanban does this by defining explicit methods to manage work flow, paying particular attention to the number of things being worked on simultaneously, and how the available resources are allocated. Alan Shalloway reviews the basic Lean Principles of “fast, flexible, and flow” along with the systemic nature of errors Kanban addresses.

Agile adoptions can only be successful if corporate values match the key values outlined in the Agile Manifesto and in agile frameworks such as XP and Scrum. Michele Sliger explains the agile values that play a key role in driving individual and team behavior. Learn the real meaning behind the often heard phrase "agile is value-driven, not plan-driven". Discover how to determine your company's values and how to compare and contrast them to agile values-and what to do if they are different.

When making choices about a system's functionality, the easiest thing is to ask yourself, "What would I like the software to do?" Unfortunately, when a team uses this approach, the result is usually constant argument, uncomfortable compromises, and that never-popular "designed-by-committee" feel. A persona is a simple model that describes an example user of a system. It's easy and fun for a team to create pragmatic personas that describe what we know about our users so we can talk about the product from their perspective.

Many teams have a relatively easy time adopting the tactical aspects of the agile methodologies. Usually a few classes, some tool introduction, and a bit of practice can lead you toward a somewhat efficient and effective adoption. However, such teams quite often are simply going through the motions-neither maximizing their agile performance nor delivering as much value as they could.
