Against the background of the integration of two internal IT service providers with different initial situations in terms of content and organization within an internationally positioned company in the energy sector, Antores GmbH supported the development and successful introduction of the joint Future Operating Model (FOM). In addition to ensuring "Commercial Readiness" at the time of the merger, the objective of the consulting services was to generate synergies, create transparency, harmonize systems and processes, renew the contractual basis for service provision and charging, take into account tax & regulatory aspects and document the new commercial model. Additionally, we provided support for the harmonization / standardization and migration of master and transactional data.
