A link is provided below to the NASA System Engineering Handbook, a document used extensively in aerospace and defense R&D, for both large and small programs. The handbook was designed by NASA to help organize and control very large development programs, and contains a considerable amount of detail, more than a Capstone team will require. However, it is an excellent reference to understand the high-level structure and flow of a design effort, the purpose of various reviews, and definitions and terms common to technology developments.
