Abstract
The demands to the short-time completion in software projects have been more and more increasing with acceleration of business speed. Although some agile methodologies have been advocated since the 1990s, they have not yet enabled management of large-scale projects sufficiently. In such situations, the theory of constraints is getting a focus of attention as a time management technique. This paper reports a practical example of project which realized short-term development by taking the theory of constraints into account, and the effectiveness of the theory of constraints is verified through the analyses of scheduling methods and application results.
