The software industry is in transition from craft work to engineering practice, but development, operational and maintenance overheads are still unpredictable and expensive. Cleanroom Software engineering is the first practical development and certification to use statistical quality control to reduce software defects and costs. It has already distinguished itself as a complete software life cycle process with sound foundations in theory and demonstrated effectiveness in practice. The Cleanroom method is one of the few fully articulated life cycle process models in software engineering today and involves: *Incremental development under statistical process review. *Formal methods for specification, design and verification. *Statistical reliability certification. A Reader in Classroom Software Engineering gathers together, for the first time, the most up-to-date material available to form an in-depth treatment of the complete Cleanroom process.
