Within service-oriented solutions, a service contract represents a fundamental artifact, as this is the only medium through which services interact with each other or other consumer programs. This creates a strong need to standardize the service contracts in order to make services reusable and recomposable as much as possible.
The service-orientation design principles help in distinguishing a service-oriented solution [14] from a traditional object-oriented solution by promoting distinct design characteristics. The presence of these characteristics in a service-oriented solution greatly improves the chances of realizing the aforementioned goals and benefits.
Service-oriented modeling is an SOA framework that identifies the various disciplines that guide SOA practitioners to conceptualize, analyze, design, and architect their service-oriented assets. The Service-oriented modeling framework (SOMF) offers a modeling language and a work structure or "map" depicting the various components that ...
In the contexts of software architecture, service-orientation and service-oriented architecture, the term service refers to a software functionality, or a set of software functionalities (such as the retrieval of specified information or the execution of a set of operations) with a purpose that different clients can reuse for different purposes, together with the policies that should control ...

Due to the fallacies of distributed computing, finding an adequate granularity is hard. [2] There is no single simple answer but a number of criteria exist (see below). A primary goal of service modeling and granularity design is to achieve loose coupling and modularity, which are two of the essential SOA principles, [3] and to address other architecturally significant requirements.
