PROJECT RELIABILITY GROWTH MODEL BASED ON CURVES OF ACCUMULATED COMMUNICATION TOPICS FOR SOFTWARE DEVELOPMENT

摘要

New trends in software development, such as agile software development, have a difficulty in conventional document-based management. Executable software has a higher priority than development documents such as detail design documents and formal bug reports. If managers depend on development reports in order to determine the project progress and the product quality, they will miss the opportunity of determining the progress and quality in agile software development. Therefore, we proposed a project reliability growth model for determining the project state without development documents. This model is based on conventional software reliability growth models. The parameters related to bugs are replaced with communication topic parameters. The concept and procedure of the model are the same as those of the software reliability growth model. By applying this model to open source projects, it is possible to detect a significant change in the project state without development documents.
