The reusability aspect of the logical architecture paradigm then shifts from individual
service implementations and private instances to a more generic collaborative technological
landscape. Here, it is required to tackle reusability and asset utilization in a more challenging operating
environment where service-oriented technological assets may be distributed across multiple
business domains and empowered by interoperable platforms.
Indeed, the asset reusability discipline, which is either exercised from within an organization??™s
internal boundaries or required by outside business partners or consumers, is all about
software dependency. This utilization aspect of a service??™s resources typically depends on its popularity,
its value proposition, its return on investment, and the quality of its offerings. Take, for
example, a customer profile service cluster that not only offers customer name and address data
