Established commercial implementation methodologies for SAP typically fail to address how requirements will be met, the criteria for testing, the framework for utilizing test tools, necessary resources for testing, estimating testing budgets, specific testing roles and responsibilities, and how test defects will be managed and resolved.
Many factors hamper successful testing at most SAP projects such as unclear requirements, inability to trace the system design to requirements, missing dedicated test teams, waiving defects without appropriate workarounds, and inadequate involvement of needed participants for testing such as subject matter experts (SMEs) for capturing requirements and end users for user acceptance testing.
Industry data shows that removing system defects in a live production environment is at least 20 to 40 times more expensive than doing so in the unit-testing phase or during the requirements gathering phase. Many defects can be eliminated or prevented altogether with thorough evaluation and peer review of requirements.
Many corporations pay expensive consulting fees to fix production problems arriving at the production help desk rather than address these problems or defects during the applicable testing phase.
The main reason that this occurs is that SAP projects often do not spend the time or have the appropriate resources to ensure that the captured requirements are peer reviewed and evaluated with objective criteria, or to construct an RTM to provide coverage for all requirements and establish objective testing criteria for each testing phase.
Another overlooked reason that causes defects that should have been resolved during testing to slip into the production environment is that individuals acting as SAP testers cannot reach consensus on testing nomenclature or the test approach.
Another challenge for testing SAP is inadequate training at all levels for either cross-matrixed testing resources or dedicated testing resources. Training is needed for testers who are participating in one-time testing efforts such as user acceptance testing, or participating in all testing efforts for execution of test cases and resolution of defects.
The test manager needs to develop the procedures for mentoring and educating all project resources who are expected to participate in testing activities.
Training consists of the following activities:

Training consists of the following activities:
- Training dedicated testers on how to maintain and install automated test tools, test management tools, and develop automated test cases.
- Training testing participants on test procedures for logging defects and reporting test results.
- Training on how to evaluate and peer review requirements.
- Training on testing nomenclature to standardize testing terms for all project members.
- Training for roles and responsibilities for resolving defects.(25.8)
