Background: Make or buy decisions is the most fundamental part in a company’s manufacturing strategy. The decision is complex and involves sacrifices whichever strategy is chosen, and before making the decision the firm should understand and evaluate the trade-offs and comparative costs of manufacturing or outsourcing. The uniqueness of family firms is that they often operate their business with non-financial goals at the centre. This study will investigate the make or buy decisions at Väderstad AB, a family owned firm that deals with decisions of make or buy on a large scale, with many thousands of parts included in their final machines, and decisions made daily whether to make or buy. There is no existing research looking at the qualitative non-financial goals and factors in family firms and how it affects the make or buy decision. Purpose: This master thesis studies the make or buy decision at a family firm. The aim is twofold, namely, to explore the potential uniqueness of family firms within the context of the make or buy decision and then to create a make or buy decision model for a family firm. This aim is explorative, i.e. to generate theory, in the realm of family firm research. Method: This is a qualitative study performed by conducting a single case study methodology. 12 Semi-structured interviews with 14 employees from all parts of the case company and the use of documents from archival records were collected as data.  The data was analyzed with the technique of 1st order concepts, etc. as developed by Gioia. Conclusion: Our analysis showed that in the context of family firms, the primary factors influencing make or buy decisions at the case company were not financial goals. Instead drivers were goodwill for customers, innovation, quality, flexibility and control which are non-financial goals. However, financial goals were not neglected, but rather costs were measured after a decision had been made, proving that it was not in the centre of their operations before and during the decision and thus, it was secondary. As a result, non-financial goals played a larger role than financial goals in the make or buy decision.
