Incremental implementation of cleanroom practices

Software managers considering the cleanroom method are often concerned that it will require more change than the organization can assimilate smoothly. Common concerns about cleanroom are addressed and the fundamentals of introducing, implementing, and improving the cleanroom process are described. Cleanroom software engineering is a managerial and technical process for developing high quality software with certified reliability. Cleanroom covers the entire software life cycles; it provides a complete discipline within which software development teams can plan, specify, design, verify, code, test, and certify software. It approaches software development as an engineering process with mathematical foundations rather than as a trial and error programming process, and is intended to produce software with error-free designs and failure-free performance
