| Why is it so hard to find Feedback Control in Software Processes? (Invited Presentation) (1996) | |||||||||||||||||
Abstract | |||||||||||||||||
| Early data on the phenomenology of software system evolution suggest that such evolution involves and is, to some extent, governedbyfeedback. This feedback may take the form of information fedback to individuals or groups as a form of learning from experience or may take the form of observation and data that areusedtocontrol some aspect of the process. For the moment, we shall put the former to one side and concentrate only on feedback to explicit control mechanisms. Initial investigations, using a basic model for feedback control, have exposed a variety of reasons why softwareprocesses are not amenable to classical feedback control: softwareprocesses are design, not production processes# control-directedprocess changes tend to be step functions, not regulatory ones, and are often as creative as the processes they control# and system development and evolution processes are still immature with little theory to guide the design and application of regulation control mechanisms.
