Interdisciplinary project teams foster the creation of new ideas and innovations to meet customer needs and to challenge competition under the pre‑condition that the team and knowledge transfer processes are running smoothly and efficiently. In practice knowledge created in projects often is lost when the team splits up and the members return to their tasks in the organisation. This leads to inefficiency as time and money is spent in inventing things, which are already known inside the organisation. The case study outlines how knowledge and potentials for improvement can be explored and synergies can be realised. 0ur approach offers guidelines to accumulate transfer and utilize knowledge acquired in projects to improve future business. Through a knowledge‑oriented concept the consulting and software implementation process of the case study's company is optimised. This offers the possibility to integrate organisational change management know‑how and furthermore it gives the opportunity for a critical reflection of finished and ongoing projects. In this process "best practices" and "lessons learned" are explored to foster a better planning and realisation of projects on the long run.
