This bachelor’s thesis addresses the question of which knowledge management concept best suits a non-profit organisation in the educational sector with high employee turnover. The thesis aims to provide a concept tailored to the organisation's needs, which provides long-term benefits. The approach seeks to take into account all departments within the organisation and meet their individual needs.

To answer the research question, multiple employees of the organisation were interviewed about their perspectives on the situation and improvements they would like to see. A survey was performed shortly thereafter to gain a quantitative overview. These two methods allowed a practical view of the current situation. Additionally, an in-depth literature review was conducted to investigate knowledge types, knowledge loss, and knowledge retention strategies. Lastly, the findings of both the status quo analysis and the literature review were combined to design a concept tailored to the organisation.

The findings highlight the importance of a concept which combines uniformity and flexibility. Therefore, a solution was sought that enables standardised handling on the one hand, while also considering the individual needs and challenges of the various departments on the other. Since there was no existing solution that perfectly suited the organisation, a new concept was created: a two-level concept comprising an organisation-wide concept and a programme-specific concept. The instruction manual and the standardised onboarding and offboarding processes specify how the knowledge retention process should take place. The toolbox on the second level, on the other hand, indicates which tools are most effective for knowledge retention. To introduce the concept, it is recommended to determine the further procedure with the team leaders of the departments as soon as possible. Additionally, a responsible person should be designated who will be responsible for the pending steps and the implementation. Ideally, this person will also check in future whether the concept is still up to date or needs to be updated. The enforceability of the proposed concept leaves room for further research.
