Abstract
The high quality is often demanded by the quick turn as SI requirement for mission-critical system (MC system at the following) construction now. In such a requirement, it exists a lot when the project manager/development worker's securing difficultly constructs the system of the project by a new worker. Moreover, contract development and a local, decentralized development by two or more companies are done, and the climate union is also difficult in the project. In such a background, I introduce the approach of the person valuing management done as one of the means to do the MC system construction by doing the climate creation that does what should pay attention to person's doing, and be done.
