Defining a Process ? A mature process is documented with process notations, ., data flow diagrams, activity diagrams, check lists, flowchart. ? Activity details: – Purpose, participants, inputs, entry criteria, work products, outputs, exit criteria, performance measure, subpractices, and work items. What Is a Software Process? ? A software process is a set of activities, methods, practices, tools, and transformations that people employ to develop and maintain software. – The associated products include project plans, design documents, code, test cases, user manuals, … What Is a Process Model? ? A process model is – a mon set of process requirements, capturing best practices, practical knowledge to guide priorities. – a structured collection of elements that describe characteristics of effective processes. ? A process model is used – as a guide to modify or create processes using practices that have been proven to increase process capability. – to assess process capability for two purposes: ? Establish a baseline for improvement. ? Measure progress as improvement activities proceed. Modeling the Software Process ? Deposing the software process, it can be viewed as a set of defect injection and defect removal activities.
