EVH GmbH provides electricity, gas, and district heating services in Halle, the largest city in Saxony-Anhalt, Germany. EVH is part of Stadtwerke Halle (SWH), a public utility group with more than 40 subsidiary companies that provides a diverse range of services.

EVH is always striving to make business processes more efficient and effective. Following the introduction of a new ERP system, the company launched a pilot to monitor the development of a new standard procure-to-pay process.

By piloting this new process, EVH hopes to encourage holistic standardization across the SWH Group. Marcus Graichen, Head of SAP ERP Management at EVH GmbH, notes: “By introducing process mining, we are making the handling of our commercial business processes quantifiable. Our goal is to help standardize processes within the SWH Group.”
