By Thinklytics Partners, SAP S/4HANA Practice
An SAP migration risk register should weight the data and reporting risks most heavily, because they cause most failures. Score each, assign an owner, and re-score.

Frequently asked questions
What belongs in an SAP migration risk register?
Each risk with a category, description, likelihood and impact scores, a combined score, an owner, and a mitigation. The data and reporting risks should carry the most weight.
Why weight data risks most heavily?
Because data is the most common cause of stalls and overruns. Registers that over-weight platform and integration risk miss where migrations actually fail.
How do we score risks?
On likelihood and impact, multiplied into a combined score. Sort by combined score and the top items almost always include several data and reporting risks.
How often should we update the register?
At each program stage. A good readiness program visibly pulls the data risks from red into manageable before a go-live date is set.
What is the most common high-scoring risk?
Committing a date and budget before measuring the data, plus duplicate master data and reporting that breaks at cutover.
Who owns each risk?
A named person, not the program generally. A risk without an accountable owner does not get mitigated.
