Abstract
We propose PM (Project Management) patterns to prevent schedule delays caused by changes in requirements on empirical studies. Changes or late elicitation of requirements during the design, coding and test processes are one of the most serious risks, which may delay project schedules. However, changes and late elicitation of requirements are usually accepted during development processes. Therefore, the PM methods for preventing schedule delays caused by changes and late elicitation of requirements during development processes are an important area of study. In this study, we examined the actual conditions of various projects which succeeded in preventing schedule delays resulting from changes and late elicitation of requirements during development processes. We were able to extract various typical PM techniques for preventing these schedule delays. The techniques, known as “PM patterns”, were also applied to other projects. The patterns were arranged on a two-dimensional framework. We discuss a framework of PM patterns aimed at solving the problems caused by changes in requirements.
