Abstract
To upgrade a project management process, it is effective to support the management of the pre-project phase (the inquiry, the estimate, and the contract). For that, we have defined the pre-project standard business process by arranging pre-project business processes of some in-house divisions. Especially, for the order type business in the plant construction field and the software development field, we have defined the detailed pre-project standard WBS that did not depend on specific products. And, we have applied standard WBS to an actual project, and verified the validity of that.
