Principle 2: Start Scoping Early
To implement a feasible, affordable, maintainable environment that fulfils the business objectives, preparations must be made well in advance to allow sufficient time to plan related efforts. Involve business users early to collect process and functional requirements, which helps ensure buy-in to the completed solution. Requirements and pre-existing assumptions should be assessed against best practices, including preconfigured content and configuration guidelines. All parties should agree and sign off on the scope. This ensures that the implementation is delivered on time and with expected quality and scope. Adopting best practices and limiting customizations will also reduce maintenance effort, especially for cloud solutions, as upgrade cycles are controlled by SAP.
A scope-change process should be agreed on to make sure the completed solution remains relevant. The process must guide decisions about the scope changes. It could include lessons learned from proofs of concept, identifying smarter ways to adapt existing business requirements to best practices, new business requirements, and the chance to leverage new best practices.
