With lots of talk about Engineering Processes, it helps to summarize the main ones, and elaborate on the applicability
These are the main processes.
|Scrum||Producing a product or sub-systems using small incremental changes with stakeholder feedback||Useful in a variety of situations, but needs to be supplemented with other processes|
|Rapid||A framework to make decisions, based on Role Assignment||Useful in large organizations with multiple stakeholders and groups|
|Rational Unified Process||A framework to engineer large systems well||Useful after a product has become large and needs to be sustained and improved|
|Six Sigma||Process improvement by feedback from metrics||One of the two Quality Processes|
|Capability Maturity Model||Record the process steps and repeat them flawlessly||Maintains the Product Quality at the current levels|
