Phase 2: Business Blueprint
The purpose of this phase is to achieve a common understanding of how the company intends to run SAP to support their business. In Standard ASAP 8 the result is the Business Blueprint, a detailed documentation of the results gathered during requirements workshops. In Agile ASAP 8 the result is a Baseline Build and Project Backlog
reflecting the solution requirements prioritized by business value.
Phase 3: Realization
The purpose of this phase is to implement all the business process requirements based on the Business Blueprint or Project Backlog. The system configuration in Standard ASAP is done in two work packages: Baseline configuration (major scope); and Final configuration (remaining scope). In Agile ASAP project team splits Realization phase into multiple releases with number of time-boxed iterations focused on building up the functionality.
Phase 4: Final Preparation
The purpose of this phase is to complete the final preparation (including testing, end user training, system management and cutover activities) to finalize your readiness to go live. The Final Preparation phase also serves to resolve all critical open issues. On successful completion of this phase, you are ready to run your business in your live SAP System.
Phase 5: Go Live Support
The purpose of this phase is to move from a project-oriented, pre-production environment to live production operation.
Phase 6: Operate

Each phase has a set of deliverables that are produced during the duration of the phase and serve as the input to follow-up phases. Each deliverable provides list of Outputs it consist of and Methods that are used to produce the deliverable.
