Abstract
In this article, actions against problems occurred during a new package development project are described as well as better package development method. The project positioned the first user of the package as "a pilot study" and initiated customized development for the first user within the package development team ahead of other customers before the package was complete. However, as individual system integration development method was used unchanged, the boundaries of the package development and applied customized development became blurred, causing successive problems when expanded to multiple users. To these problems, we made analysis with a view from the field, solved the problems by devised actions, and could successfully put the project back on track. This article describes these actions in detail. Since these actions against the problems were basic ones viewed from the result, they can be solutions even for projects other than package development.
