The company's V1: Agile Enterprise product, available in either local or hosted versions, is a planning and product management tool for agile development. VersionOne defines agile as a feature-driven approach to development that delivers software in short iterations -- a few weeks as opposed to every couple of years.

"We manage the projects, the schedules, features, defects, tests, all of those noncode assets that flow though the agile development lifecycle," said Robert Holler, CEO of VersionOne.

The API featured in the Summer 2006 release, called V1: Agile API, uses a secure Web services interface to allow developers to integrate V1 with third-party offerings such as requirements management tools or defect management trackers. The feature is technology-independent, working with Java tools or Microsoft Visual Studio.

Data is synchronized between V1 and the third-party offerings. For example, a developer could enter a bug into VersionOne's software, whereupon it could be queried on its status in V1 and updated in the user's source system.

"It's basically opening up the information so you can integrate with any other system in your development lifecycle and really automate the flow [of information]," Holler said.
