Atern Process – The Lifecycle
- Feasibility – deciding whether a proposed project is viable from both a business and a technical perspective
- Foundations – establishes firm and enduring foundations for the project according to the essential perspectives of business, solution and management. Level of detail is limited, but it must be possible to demonstrate how business needs will be met.
- Exploration – used iteratively and incrementally to investigate detailed requirements and translate them into a viable solution
- Engineering - used iteratively and incrementally to evolve the solution created during Exploration to full operational readiness
- Deployment – getting the solution into operational use or ready for market
