A three-layered process of documentation A three-layered process of documentation: (1) First, there is the field notebook. This is where the actual numbers are recorded, together with passing observations relevant to the interpretation of these numbers. Paper is still proving more durable than electronic data. (2) The journal is a parallel record to that of the notebook—a daily account of events, thoughts, and observations. (3) Last of the three strata, then, are the publications. Traditionally, in science, these are articles in academic journals leavened with chapters in books. To be successful, a young scientist need aspire to no more than these two forms of output together with their oral versions at interminable conferences and meetings of learned societies. There came a time in my scientific development, however, when other forms of publication became important: magazines articles, and writing books.

Solution to evaluation and back again A second reason the systems engineer’s design is never completed is the solution offered to the original problem usually produces both deeper insight and dissatisfactions in the engineers themselves. Furthermore, while the design phase continually goes from proposed solution to evaluation and back again and again, there comes a time when this process of redefinement must stop and the real problem be coped with—thus giving what they realize is, in the long run, a suboptimal solution.
