5 Service Governance Practices for Effective Reuse

Pursuing service based systematic reuse or business process development? Then, these five practices will help your teams achieve increased level of service reuse.

  1. Manage a common set of domain objects that are leveraged across service capabilities. This could be a library of objects (e.g. Plain Old Java Objects) or XML Schema definitions or both. Depending on the number of service consumers and the complexity in the domain, there will be need for supporting multiple concurrent versions of these objects.

  2. Provide common utilities for not only service development but WSDL generation, integration and performance testing, and ensure interoperability issues are addressed

  3. Appropriate functional experts are driving the service’s requirements and common capabilities across business processes are identified early in the software development lifecycle

  4. Governance model guidelines are clearly documented and communicated  – for example, there are a class of changes that can be made to a public interface such as a WSDL that don’t impact existing service clients and there are some that do.

  5. Performance testing needs to be done not only during development but during service provisioning – i.e. integrating a new service consumer. If your teams aren’t careful, one heavy volume consumer, can overwhelm a service impacting both new and existing consumers. Execute performance testing in an automated fashion – every time you integrate with a new client to reduce risks of breaching required SLAs

What additional practices do your teams follow?
