Integrated development for computer-based systems

This paper describes an integrated systems and software engineering process whose purpose is to enable systems and software engineers and project managers to develop software-intensive systems more efficiently. The process model accomplishes this goal by defining a set of management and technical activities and the information flows that integrate them. The model may be tailored to a particular system development by decomposition of the process to mirror the evolving decomposition of the system itself with both management and technical activities allocated to each element of the system, and with defined information flows between activities at adjacent levels. The model calls for both a long-term development plan and a series of increment plans for each element and requires that risks are analyzed before each plan is defined. The process complies with major systems and software engineering standards.
