The ASAP Roadmap provides the methodology for implementing and continuously optimizing your SAP System. It divides the implementation process into five phases and offers detailed Project Plans to assist you (in Microsoft Project format). The documentation stored at each level of the Roadmap tree structure contains recommendations on implementing your SAP System and links to helpful tools and accelerators.
The implementation of your SAP System covers the following phases:
In this phase you plan your project and lay the foundations for successful implementation. It is at this stage that you make the strategic decisions crucial to your project:
Define your project goals and objectives
Clarify the scope of your implementation
Define your project schedule, budget plan, and implementation sequence
Establish the project organization and relevant committees and assign resources
In this phase you create a blueprint using the Question & Answer database (Q&Adb), which documents your enterpriseu2019s requirements and establishes how your business processes and organizational structure are to be represented in the SAP System. You also refine the original project goals and objectives and revise the overall project schedule in this phase.
In this phase, you configure the requirements contained in the Business Blueprint. Baseline configuration (major scope) is followed by final configuration (remaining scope), which can consist of up to four cycles. Other key focal areas of this phase are conducting integration tests and drawing up end user documentation.
In this phase you complete your preparations, including testing, end user training, system management, and cutover activities. You also need to resolve all open issues in this phase. At this stage you need to ensure that all the prerequisites for your system to go live have been fulfilled.
Go Live & Support
In this phase you move from a pre-production environment to the live system. The most important elements include setting up production support, monitoring system transactions, and optimizing overall system performance.
1. Project Preparation, in which the project team is identified and mobilized, the project standards are defined, and the project work environment is set up;
2. Blueprint, in which the business processes are defined and the business blueprint document is designed;
3. Realization, in which the system is configured, knowledge transfer occurs, extensive unit testing is completed, and data mappings and data requirements for migration are defined;
4. Final Preparation, in which final integration testing, stress testing, and conversion testing are conducted, and all end users are trained; and
5. Go-Live and Support, in which the data is migrated from the legacy systems, the new system is activated, and post-implementation support is provided.
