Feature-Driven Development: An Agile Alternative to Extreme Programming Feature-driven development (FDD) has the more traditional progression of a systems-engineering life cycle mode as compared to agile methods. It uses distinct phases in its iterations while still being highly iterative and collaborative. FDD does conduct up-front planning, design and documentation and relies very heavily upon domain modeling.

An Agile Perspective on Branching and Merging This article focuses on branching and merging. We present some background for branching and merging, and consider some of the implications for agile development in particular. We also hope to reduce some of the suspicion that many agile developers have of branching. The article assumes some overall branching knowledge and yet revisits some particular details that often seem to confuse people. This is a fertile area which we will continue to expand on in future articles.

Not Your Father's Test Automation If you think that test automation is mostly about executing tests, then you're missing out on a big opportunity. Or rather, you're missing a lot of small opportunities adding up to a big one. Consider this: stop thinking about test automation as merely executing automated tests, stop thinking about test automation as something you need expensive tools for, and start discovering automation you can implement in a couple of days and usually with extremely inexpensive tools or tools you already have available. In this week's column, Danny Faught and James Bach suggest taking a more Agile approach to test automation.

Agile Codeline Management Software developers often view version management tools and techniques as a necessary evil. This is particularly true of developers practicing agile techniques. However, version management, can be an aid to agility rather than something that gets in the way.

The Need for Agility in SCM What is agility? Summarizing from last month's article agility is “The ability to both create and respond to change in order to profit in a turbulent business environment…. What is new about agile methods is not the practices they use, but their recognition of people as the primary drivers of project success, coupled with an intense focus on effectiveness and maneuverability.” [2]

Can You Negotiate Quality? XP teams have the right to do their best work. On the other hand, customers have the right to specify and pay for only the quality they need. How does one reconcile two potentially conflicting points of view? Is quality negotiable? If so, how do we go about negotiating it? This paper will explore the following questions: Is quality negotiable? How can we negotiate quality? What are internal and external quality, and are either or both negotiable? What's the XP tester's quality assurance role? How far should testers go in helping the customer define acceptance criteria?
