Complex Adaptive Systems Engineering (CASE)
White, B.E. 2008. "Complex Adaptive Systems Engineering (CASE)." Paper presented at Understanding Complex Systems Symposium, University of Illinois at Urbana Champaign, 12-15 May 2008.
This source is considered a primary reference for the Enterprise Systems Engineering Background article.
This most comprehensive presentation of CASE consists of a full paper, an annotated PowerPoint presentation, and an audio track of the talk. This might be a good place to start in contemplating an alternative approach to systems engineering in very complex environments where people are considered to be part of the system. Consequently, one can better understand how ultimate system improvements cannot be pre-specified and that events can be quite unpredictable.
