The main purpose of this paper is to present the problem, identify goals and discuss higher education e-learning services. The basis for the discussion is the development of process approach to measuring operational efficiency and improving the quality of services. The paper presents various perspectives on e-learning and definitions of service efficiency. For the sake of service identification, one of the most common business processes classification, i.e. APQC Process Classification Framework, was employed. According to the approach suggested by the APQC in the article, there are two groups of processes. The first group consists of the operating processes of e-learning, and the second one - of management and support processes. Another section illustrates the example of e-exam service business model presented with the use of the map of business processes. It also sets out the assumptions and results of time simulation of e-exam service. The summary presents conclusions and suggested directions for further research.
