Abstract
As the business environment is changing swiftly, there are a growing number of small-scale projects with short-term delivery and high-quality requirements, as represented by e-Business application development projects. In rapid development projects with such special constraints, the individual productivity can significantly affect the productivity of the entire project. The project work includes not only the development but also the work related to project management. In the past several years, tools that support development itself have proliferated, but the same cannot be said of tools that support project management. There is a strong potential for increasing productivity by breaking through the current situation. This paper considers the application of a PM tool for small-scale projects along with the development of a lightweight PM tool that supports collaboration work.
