## The use case: how HARMAN International deploys Celonis

HARMAN uses Celonis to analyze its 20-year-old SAP ECC environment, including custom codes and programs, as part of its S/4HANA migration. It adds process context to customizations, fills documentation gaps, and helps global process owners decide which as-is elements to carry into the to-be processes.

Summary written by usedby from the source page, in English. The figures are those of Celonis and HARMAN International, not ours.

> HARMAN can leverage Celonis to add business process meaning and context to all the customizations in ECC. That is, HARMAN is now able to see where each is being used in the process, who is using them, and at what frequency.

> Celonis can really help the Global Process Owners see their ‘as is’ process and make decisions for the ‘to be’ process.
