Letter from the editor

The move to agile techniques may seem impossible to managers of large software projects -- those that involve thousands of lines of code and dozens or even hundreds of contributors. But when teams begin to think in terms of software delivery instead of software development, and project objectives shift from the completion of activities to the delivery of results, teams large and small are taking their first steps toward agile thinking. In this issue, Rational methodologist Walker Royce provides his latest thoughts in the area of software economics, focusing on ways businesses of varying size can understand and move toward "agility at scale." We also take a look at the new IBM Measured Capability Improvement Framework; the concept of "design debt"; process mashups; enterprise architecture for systems engineering, and more.
