STUDY
PLAY
Process
Key attributes
- Process is represented as a spiral rather than as a sequence of activities with backtracking.
- Each loop in the spiral represents a phase in the process.
- No fixed phases such as specification or design - loops in the spiral are chosen depending on what is required.
- Risks are explicitly assessed and resolved throughout the process.
Objective Setting
Specific objectives for the phase are identified.
Risk assessment and reduction
Risks are assessed and activities put in place to reduce the key risks.
Development and validation
A development model for the system is chosen which can be any of the generic models.
Planning
The project is reviewed and the next phase of the spiral is planned.
