Continuous Integration: The Project Heartbeat

Published: 11 December 2008

ID: G00203619

Analyst(s): Kirk Knoernschild

Summary

Continuous integration is the practice of integrating, building, testing, and delivering functional software on a scheduled, repeatable basis. The prime directive of continuous integration--software that works--offers a compelling value proposition. By leveraging a software delivery paradigm that promises functional software at regular and frequent intervals, teams can reduce the development risk and cost, improve the quality, and speed the delivery of software. Continuous integration is the cornerstone of that delivery paradigm. In this Application Platform Strategies overview, Analyst Kirk Knoernschild examines the benefits of continuous integration and discusses many common challenges encountered on the path toward adoption.
