SvcV-10a Services Rules Model

The SvcV-10a “Services Rules Model” is to specify functional and non-functional constraints on the implementation aspects of the architecture (i.e., the structural and behavioral elements of the Services Model). The SvcV-10a describes constraints on the resources, functions, data and ports that make up the Service Model physical architecture. The constraints are specified in text and may be functional or structural (i.e., non-functional). [1]

The intended usage of the SvcV-10a includes: [1]

  • Definition of implementation logic
  • Identification of resource constraints

Guide:  DoDAF Architecture Framework Version 2.02 – Page 191

The SvcV-10a describes the rules that control, constrain or otherwise guide the implementation aspects of the architecture. Service Rules are statements that define or constrain some aspect of the business, and may be applied to: [1]

  • Performers
  • Resource Flows
  • Service Functions
  • System Ports
  • Data Elements

In contrast to the OV-6a “Operational Rules Model”, the SvcV-10a focuses physical and data constraints rather than business rules.

Constraints can be categorized as follows: [1]

  • Structural Assertions – non-functional constraints governing some physical aspect of the architecture
  • Action Assertions – functional constraints governing the behavior of resources, their interactions and Resource Flow exchanges
  • Derivations – these involve algorithms used to compute facts

Where a Service Rule is based on some standard, then that standard should be listed in the StdV-1 “Standards Profile”.
Some Service Rules can be added as annotations to other models. The SvcV-10a then should provide a listing of the complete set of rules with a reference to any models that they affect.

  • The DoDAF descriptions in this website are very generic and are mostly taken from the DoDAF Architecture Framework website. Make sure you visit the actual website for the most update information and a more thorough explanation of each viewpoint.
  • DoDAF Version 1.0, although outdated, has some good examples on how to construct AV’s, OV’s, and SV’s.
