Making Potsdam a better place to live – that’s the mission statement of the city’s own group of companies ProPotsdam. Among the methods the company employs to achieve this objective are multifaceted construction and housing projects as well as social commitment. The company manages more than 17,800 apartments and provides new housing in Potsdam through innovative construction projects such as upgrading and rebuilding a former tram depot or military barracks. The support, management, rebuilding/renovation measures and the organisation of the social projects require a sophisticated digitisation concept. This is where PROMOS comes in. For example, ProPotsdam was able to digitise its entire company management and residential property management without impairing operating processes by implementing the new operating system SAP S/4HANA®. Jörn-Michael Westphal has been managing director of ProPotsdam GmbH since 2000 and took responsibility for the majority of the digitisation project in cooperation with PROMOS. We wanted to find out from him how he and the company maintain their success and drive innovation in Potsdam. We asked him seven questions. Here are his responses.
