Abstract
This paper presents the practice of the project management dealing with concurrent multi-systems development. The orthodox approach is first to develop the reference system and after to diverse it into customized systems according to users' request. However, the restricted environment forced us to develop all the multiple, almost ten, systems concurrently. Although, this experience, both in business context and development size, was new to us, we conducted the project by focusing on risk identification and taking all the major risk responsive steps just before the execution. We divided the whole phase into two phases: centralized concurrent phase where requirement through implementation cycle took place, distributed concurrent where after testing and integration cycle took place. We turned the first phase into centralized sequential, which was more convenient to handle, by unifying all systems as identical software. During the second phase we focused to construct the information sharing system on the Web for both version control for the identical software and faulty detection & fix report. This information sharing system run on web and could be accessed from anywhere through the public line by the authorized users so that it was used after the shipment until the user acceptance test. With this adaptive project management, the whole project went successful.
