Innovation on Top of Stability Enhancement Packages reduce conflict between stability and innovation
INNOVATION Fast and easy introduction of business innovation at any time when needed
ENHANCEMENT PACKAGES = INNOVATION + STABILITY
• Enable IT to continuously provide new functionality: Installation of enhancement packages as part of routine maintenance
• Selective, non-disruptive activation of innovation at any time - driven by business needs
STABILITY Stable and robust business processes for maximum efficiency and low TCO Routine deployment of support packages to sustain compliance © 2011 SAP AG. All rights reserved.

Enhanced by Custom Code Customer individual requirements Completion of functionality
Having Custom Code is “ok” – as long as it is based on an educated decision Implications regarding the loss in “built-in” capabilities need to be properly addressed Doing it “right” helps to minimize the incremental effort to develop and operate your code

Custom Code Reality
“
Creating and Managing Custom Code adds to your Bill. How much? That is not entirely clear. We can reduce it Today!
Figures from typical customer systems* 8000 objects in the customer namespace and 1500 modifications or enhancements 65% of them have not been used within the last 4 weeks up-to 15% are identical or very similar to each other(Clones) some more became obsolete through recent SAP standard functionality
30-50% of them need to be adjusted on the occasion of a SAP standard upgrade 20% of the system resources are attributed to the execution of custom code Code inspection returns several hundred severe messages per development package
These inefficiencies alone can equate to an overspend on system support of between €250,000 - €2 million per annum depending upon the size of the SAP system and extent of custom code. © 2011 SAP AG. All rights reserved.

Four dimensions of Custom Code
Business Criticality
“
Missing information about mission critical business processes and use of custom code is a top issue Questions out of information deficit:
!
Which of my business processes use custom code? Which business processes are currently in use? How can I better take advantage of the current capabilities? How can I ensure the support?
“
How can I consolidate or standardize my business processes? This is essential for an efficient and successful management process!

Optimization with Custom Code Management Regular data extract
Optimizations
…. Analysis of custom code situation is fact based (holistic approach, anamnesis). The ‘Single source of Truth’ is established .
Optimization follows the minimal-maximal principle. Lowering the TCO by selection of the right optimizations. Sustainable optimization along the life cycle.
Generate city model after optimization
Optimizes existing custom code environments. The Library as monitoring tool to determine custom code healthy level. Close the loop between proactive and reactive optimization.
