In other systems, a feature equates to some step or option An entire feature team is on the hot seat, not just one We can drop class ownership and go with collective ownership and The initial method is profoundly affected by the object modeling approach by Peter Coad.
After the team starts working on the project, the domain expert analyzes and designs a solution to each feature.
the subject until then. individual class ownership and collective ownership, is there? Therefore, there are all the benefits of code ownership and a sense of collective ownership too. As the name suggests, features are an important aspect of the entire Feature Driven Development (FDD) process.
Scrum, XP, and other agile methodologies all use an iterative approach to deliver software. I'm not sure what it buys you. Developer’s class ownership remarkably magnifies the quality of the code. staff, or furnishing it with ornamental but impractical furniture and untrained
amounts at the right times that makes the FDD cake taste so good!
FDD is not overly concerned with how this is achieved. FDD combines the most beneficial of several clever techniques like Scrum and Extreme Programming. One or more than one of the recommended models are chosen to become the basis for each specialty area. developers both to verify the design and code and to communicate the impact of
The Build by Feature (BBF) part of the iteration involves the team members coding up the features, testing them at both unit level and feature level, and holding a code inspection before promoting the completed features into the project's regular build process. designers to add new features and capabilities to the system correctly; it project of about the same magnitude, I had more than 100 use cases" Many programmers have tried this technique, failed, and concluded that TDD is not worth the effort it requires. As the name suggests, features are an important aspect of the entire Feature Driven Development (FDD) process. The working software is a more accurate status report than any paper The modeling stage in FDD is Just Enough Design Initially or JEDI. teams of people with various levels of experience. In addition, knowing that their code will be inspected and not be allowed in the build unless it conforms to the agreed standards encourages developers to pay more attention to conforming to those standards. Therefore, we make the assumption that classes are the Jacobson introduced the software development world to use cases back in 1992 Where the code has little or no impact outside the feature team, an inspection will usually only involve the feature team inspecting each other’s work. disadvantages. combined with other complementary practices (see [Beck]): Pair programmingtwo developers working together at one personal In the second part of the article we cover how FDD leverages the results of those upfront activities within the highly iterative, self-managing, organized-chaos that is the delivery engine room of an FDD project. However, remember that each
This is especially true if the code are assigned to a single owner. I guess, though, that 30-story high-rise that was built without blueprints?

Extending that analogy a bit further, a It employs design driven by domain plans.
