A medium-sized west-European telecom company experienced a worsening trend in performance, indicating that the organization did not learn from history, in combination with much time and energy spent on preparation and review of project proposals. In order to create more transparency in the supplier proposal process a pilot was started on Functional Size Measurement pricing (FSM-pricing). In this paper we evaluate the implementation of FSM-pricing in the software engineering domain of the company, as an instrument useful in the context of software management and supplier proposal pricing. We found that a statistical, empirical, evidence-based pricing approach for software engineering, as a single instrument (without a connection with expert judgment), can be used in distributed environments to create cost transparency and performance management of software project portfolios
