Mission critical software can be defined as software that a system requires to perform its mission. Mission critical software may also be safety critical software. Whether mission or safety critical, software is an integrated, crucial aspect in the development of today's complex systems. If the software fails, or is not able to perform its intended purpose, there is a risk of system failure. Critical software requires additional rigor during the design, development, release, and test life cycles to help prevent system failures. This additional rigor may be imparted through proven processes and analytical methodologies.
In this dissertation, systems engineering principles are used to develop an analysis driven, quantifiable, Mission Critical Release Readiness Methodology (MCRRM) for releasing mission critical software, focusing on the decision to release software from the development process to the customer. A software release occurs in order to document the current software and transfer the software to the customer. Multiple factors affect when to release the software. The mission critical release readiness methodology is developed through rigorous application of the systems engineering process starting from the customer needs through design, development, implementation, test, and verification and validation of the process itself. The application of the methodology is intended for projects with multiple subsystems with varying levels of critical software being released as part of an overall system. Validation and Verification (V&V) of the methodology was accomplished via thorough testing and representative case studies.
