Abstract
In order to eliminate projects with large cost overruns, we have started company-wide "Hitachi Phase-Gate program" to improve the organizational project management. Since Hitachi has a wide variety of business operations, we first analyzed best practices in advanced business divisions, and developed "Phase-Gate Mutulity Model." Using this model, we have assessed and improved the project management process of the target divisions. As a result, we found that our Phase-Gate process is effective at governing and controlling projects, in wide range of divisions and development processes. We also found that this model is useful as a tool to improve project management process to a division.
