  Process Model ofFDD • FDD consists of a minimalist and five-step process that has the following steps: – Develop an Overall Model – Build a Features List – Plan by Feature – Design by Feature – Build by Feature

  • For technicalreviews, mandated code inspections are performed in FDD. • Customer involvement is realized in the first step (develop an overall model) and in the fourth step (design by feature). • When the number of new features exceeds ten percent, the project manager asks top management. – Scope or time is rearranged.

  Feature Driven Development(FDD) • FDD has two important roles: chief architect and chief programmer. • Chief architect leads to draw the overall model. • FDD is an architecture-centric development model. • Chief programmer leads the programmers through the feature sets.

  Feature • A featureis a client-valued function that can be implemented in two weeks at maximum. • Longer features are broken into smaller features. • A feature is FDD’s form of a customer requirement. • For a feature, there are three important parts: – action – result of the action – object related with the action

  Feature Teams • Featureteams are temporary groups of developers formed according to the features. • Usually there are multiple feature teams. • A developer can take role in more than one feature teams.

  Class Ownership • Classownership is important in FDD. • Every class belongs to a specific developer. • Class owners have the responsibility for all changes in implementing new features. • Quality classes are developed using class ownership. • Class owners becomes expert for their classes.
