This paper discusses the potential benefits of incorporating a goal-oriented perspective to Business Process Management (BPM) from a methodological point of view, with a focus on the BPM Design and Evaluation phases. To achieve this aim, we examine the current activities of the BPM lifecycle and on the basis of that, the lifecycle is increased with new activities related to the modeling of business services and goals. In the BPM design phase, we suggest the integration of business services, goals and KPI modeling to the previously modeled business processes, also describing how the existing methods in goal and KPI modeling can be used to perform such representation. In the Evaluation phase, we discuss how the previously modeled KPIs can be evaluated in terms of operational data. The information produced by the KPI monitoring enables one to verify whether the business goals are being adequately fulfilled by the enterprise architecture. Further, business services can be evaluated with respect to their ability in adequately aggregating value for the final customer.
