GRANIT brings people, processes, and projects together—operationally, on-site with clients, and with a project management system that lasts. For its own internal management, the Berlin-based consultancy relies on ZEP: previously, assigning suppliers, work packages, and cost structures took three days and still only provided half the certainty. Today, it is a 30-minute routine at the end of the month. The results are so convincing that GRANIT is now a ZEP reseller partner, recommending the solution to clients whenever cost structures remain opaque.
