Software systems have a growing importance in how services are delivered in the present-day. New methods and technologies are constantly introduced for realizing novel services in a wide range of industries. In this study, stakeholder involvement in the development of financial service software system is examined, as software has been integral to the delivery of financial services. Two projects are selected for their varying degrees of product and service content. Both teams used an adapted stakeholder identification framework developed for the healthcare industry to identify stakeholders and their involvement need in the development projects. The suitability of this framework for financial service software development, and the differences in stakeholders for the development of new software systems of dissimilar product-service mix are discussed in the paper. Four insights into the influence of product-service ratio in stakeholder involvement are gained in the perspectives of product quality, relationship management, product support by customer, and service delivery process.
