Frequently asked questions
What should an S/4HANA migration checklist cover first?
The data, not the platform. Measure readiness, decide your path on evidence, protect reporting, staff the data work senior, and commit to a date only after measuring.
What questions should a CIO ask before committing?
Have we measured the data with evidence? Do we have a blueprint of what moves and what is retired? Which reports break? Who owns the data outcome and how senior are they? Was the timeline set before or after we measured?
How do we choose between brownfield and greenfield?
Brownfield converts and is cheaper, 9 to 18 months, but carries legacy debt forward. Greenfield rebuilds on a clean core, 18 to 36 months and pricier. The deciding question is how much of your current process and data is worth keeping, and the assessment answers it with evidence.
What matters during the program?
Funding data prep at 25 to 30 percent of effort, keeping the data workstream senior and off the critical path, cleaning before the move, planning reporting continuity, and reconciling every load to source.
Why lead with data instead of the platform?
Because the platform works. Migrations stall on data and reporting, and about 30 percent run late or over budget for that reason. A checklist that leads with the platform misses where the risk actually is.
What is the honest test?
If the readiness questions are uncomfortable, that discomfort is cheap to resolve now and expensive at cutover. Most overrunning programs failed this checklist before they wrote a line of config.
Where do we start?
A readiness assessment if you are scoping, or a four-week Blueprint if you are ready to plan the move.
