The challenges of servitization have gained significant attention from both academics and practitioners, as more firms in the industrial sector are seeking marketing opportunities leading to business growth through the adoption of a service strategy. Although existing research has explored its challenges from multiple perspectives, this is largely fragmented and the studies offer little understanding of the impacts of the challenges on the realisation of servitization benefits and improvements in business performance. This study, therefore, aims to create a formal construct of the challenges and develop a set of hypotheses through a systematic review of the servitization literature to build a theoretical model explaining the underlying relationships. Five challenges are identified: organisational structure, business model, development process, customer management, and risk management. The indicators of each challenge are discussed to support the establishment of hypotheses. This study contributes to the current body of knowledge by reaching a clear conclusion from the fragmented literature and brings together five challenges to explore their impacts on the overall business. •This paper aims to investigate the challenges of servitization through a systematic review of the relevant literature.•Five strings of servitization challenges are identified as a result of the review.•These challenges have negative impacts on the realisation of expected benefits and improvement of business performance.•A theoretical model is created to illustrate the correlations among the challenges, benefits and firm performance.
