Why have a process?

• Create a product that users want.
• Make the process manageable and predictable.
• Capability Maturity Model (CMM) from the Carnegie-Mellon University Software Engineering Institute defines five levels of "maturity".
• Traditional development process: Waterfall (Analysis, Design, Code, Test).
• Spiral process (Risk Analysis/Systems Analysis/User Feedback, Design, Code, Test/User Feedback).
• Objectory - defines the four project phases of Inception, Elaboration, Construction, Transition.
  • Completion of each Objectory phase marks a major milestione.
  • Objectory uses iteration to make complex projects possible.
• The process defines ways to make iterative projects manageable.
• Model the system before developing it (in the same way an architect models a new facility before building it).
