Performance tuning is not a one time exercise. Just like a car needs service, any large BI/EPM implementation needs health checks done and performance tuning done regularly.
We consider a holistic approach to performance tuning from hardware to software, from BASIS layer to application layer. We look at
- Architecture and design.
- The data models.
- The logic scripts and ABAP BADI.
- Your dataflow from ECC to BI to EPM.
- Your dataflow within EPM.
- Your frontend reporting and schedules.
- Your user experience.
