Circle of Life, Spiral of Death: Are XP Teams Following the Essential Practices?

摘要

Many of the twelve carefully defined practices of Extreme Programming are tightly coupled. The various practices have checks and balances on each other and are, in many ways, dependant on each other. Therefore, neglecting essential practices can have sub-optimal or negative consequences to team results. The practices that are actually utilized in team development can often be attributed to the perceptions of the value and difficulty of the practices by the developers on the team.

In general, these developers we surveyed valued and utilized most of the practices.
