The method of the present invention to re-factor, rationalize, and prioritize a
service model and to assess service
exposure in the
service model is illustrated. To be dedicated to every
client's success means, in this context, to be sure we are building the right service portfolio for the
client that has the highest relevance to what they do, what their objectives are, and what they aspire to achieve. Therefore, we need to periodically pause and review the
service model as it stands, infant or mature, and validate its relevance from a
client's perspective. This process is called rationalizing the service model (or portfolio). This review can lead to changes (called re-factoring) in the service model due to a re-prioritization. Some services will become more important, others will sink in priority. Thus, the method of the present invention is called service re-factoring and rationalization (SRR). The service model is reviewed and re-factored and the service portfolio and service hierarchy are refined,
exposure decisions are made, and finally the service model and its constituent parts are rationalized based on the re-factoring and
exposure decisions. Another technique called Service
Litmus Tests (SLTs) is leveraged during service re-factoring and rationalization. SLTs are set of gating criteria to select and filter a set of (candidate) services from the service portfolio for exposure. A Service
Exposure Assessment Toolkit (SEAT) is also presented in the present invention. SEAT is a
mathematical model to facilitate making exposure decisions for services and prioritizing the services in the service model.
