This master thesis report aims to highlight the importance ofinterorganizational relationships between experienced serviceproviders and emerging biopharmaceutical (EBP) companies within theSwedish healthcare industry. A shift in innovation strategiesregarding new pharmaceutical- and medical device products hasprompted a paradigm shift within a complex industry wherecollaborations between organisations has become increasinglycrucial. With a better understanding of how these companiesoperates, increased collaboration efforts could result in a fasterand more precise product development with new products reaching themarket improving the health for people around the world. In order toallow experienced service providers to enhance services towards EBPcompanies, a fundamental understanding of how decision makers withinthese EBP companies prefer to conduct relationships is needed. Wehave examined relationship preferences of EBP companies byconducting a qualitative case study through 14 interviews withdecision makers combined with a quantitative conjoint analysis.Eight factors was identified as important for when EBP companiesdecide to engage with a service provider: cost behavior,professional competence, adaptability, communication, personalrelationship, stability, EBP insight and size. The factorsadaptability, personal relationship, cost and size were used in theconjoint analysis to determine their relative importance which showthat adaptability and cost behavior was of the largest importance.With descriptions of each factor, we have provided a meaningfulguide to action of how to address these factors as a serviceprovider. The relationships is largely investigated as relationshipsbetween contract research organizations (as service providers) andEBP companies, but we have created a framework applicable forservice providers within the healthcare industry in general.
