A typical context is that there are several semi-independent business units (BUs) with their own IT environments and, at one moment, the top management decided to introduce shared services.
Certainly, it is a daunting task because it touches application portfolio and operations. There is experience from a big company (500+ BUs) that several company-wide IT initiatives to bring standard applications to all BUs have failed. Because all BUs have different level of computerization, a standard application from the IT department is not good for everyone.
It seems that “application” (as a container of functionality) is too “big” and “smaller” containers of functionality are necessary. Thus services (as small containers of functionally) and processes (as a practice to assemble bigger services from smaller ones) should be used. In this case, shared services can be introduce as the following.
