Clean core, decided on process evidence.
We mine the core before we migrate it – so S/4HANA scope is settled by data, not by defending custom code.
You are paying to migrate custom code nobody still needs.
Six weeks of process mining removed more S/4HANA migration scope than it added.
What the evidence changed
-72%
Custom objects carried into the new core.
184
Objects traced to the exception that created them, and the owner who still needs it.
2
Quarters of testing effort removed with the scope.
S/4HANA replaces your system of record. Not your shared mailbox.
Migration changes the technology underneath the process and leaves the hand-overs, the approval detours and the spreadsheet in the middle exactly where they were. Most teams discover this during testing, when change costs the most.
Mining first turns clean core from an architectural principle into a list of decisions, each with the process evidence attached.
Clean core is a process decision, not a technical one.
Planning a migration? Mine the process first.
The arguments you settle now are the ones you would otherwise settle in testing.
