Agile development approaches are moving into the mainstream. They are no longer relegated to small co-located teams. Large application development organizations in and outside of IT are betting their businesses on globally distributed teams using agile methods to create and maintain their products. In these organizations, the Agile Manifesto's principal to value individuals and interactions over process and tools is impossible to realize. The complexity created by scale cannot be managed without judicious use of both process and tools.

Fast cars, flat-screen television, high definition gaming consoles, and dual core processor equipped laptops: the amenities of modern technology rule us. Computers are an integral part of our lifestyle and work-life, and many people define themselves by their choice of tools to complete tasks. Those interested in implementing agile frameworks are no exception, often voting to use electronic tools before exploring alternatives. This article is meant for the open-minded, ready-to-explorer surrogate who is not afraid of being a low-tech hippie in times of high-tech espresso machines.

I think that the person most affected by the introduction of agile or extreme programming techniques is not the software or quality assurance engineer, but the build manager. Agile techniques are a throwback to the age when developers were able to work on small projects in small teams. Each developer once again concentrates on small building blocks of code and integrates regularly with other developers to ensure that the overall software project is progressing. For developers, agile techniques are a natural fit because they reflect how developers like to work best: on small, manageable pieces of code with regular feedback. However, even though developers are working on small sections of code, their overall projects are now large and continually growing. And it's the large body of code that the build manager is expected to work with, not the manageable chunks. While daunting, this precipitous increase in builds can be managed by carefully implementing continuous integration and making fast, automatic builds the quot;heartbeatquot; of your agile development.

Clarify the fuzzy front end of project planning by focusing on the overall vision. In this column, Johanna Rothman says clear project vision helps everyone involved in the project move forward better and more smoothly than a detailed project schedule.

Afraid of what you're missing by testing only 7 percent of your code? Forget your formal code inspections; Jason Cohen enlightens us on the merits of bringing lightweight code inspection to your organization.

Everyone knows the importance of well-defined functional requirements. We want our products to work, don't we? But how many of us are paying as much attention to defining our non-functional requirements? In this historically focused feature, we learn from past mistakes the potentially disastrous results of inadequately tested NFRs.

In the countdown to a product release, leaving load testing for last is a risky maneuver. In this month's cover story, Rex Black and Barton Layne present a case study of a project on which they adhered to a four-step strategy. By following these four steps, they were able to alleviate those nasty, end-of-project performance surprises.
