SV-7 Resource Performance Parameters Matrix v1.2
The SV-7 is the Resource Performance Parameters Matrix and depicts the performance characteristics of a Resource (e.g. system, role or capability configuraiton).
Background:
The Resource Performance Parameters Matrix expands on the information presented in an SV-1 by depicting the characteristics of the Resources shown in the SV-1.
Usage:
- Definition of performance characteristics
- Identification of non-functional requirements (input to SRD)
Data objects:
The data in an SV-7 can include:
- Resource (system, role, or capability configuration)
- Measurable Property
- Qualitative Property
Relationships Between Key Data Objects (Simplified from M3)
Representation:
- Tabulation
Detailed Product Description:
The Resource Performance Parameters Matrix View specifies qualitative & quantitative characteristics of resources. It specifies the performance parameters of each resource. The performance parameters are selected by the architect and end user community.
SV-7 is typically a tabular view.
Performance parameters include all performance characteristics of resources for which requirements can be developed and specifications defined. The complete set of performance parameters may not be known at the early stages of Architecture definition, so it is to be expected that this Product will be updated throughout the resource’s specification, design, development, testing, and possibly even its deployment and operations life-cycle phases.
One of the primary purposes of SV-7 is to communicate which characteristics are considered most crucial for the successful achievement of the mission goals assigned to the resource. These particular parameters can often be the deciding factors in acquisition and deployment decisions, and will figure strongly in systems analyses and simulations done to support the acquisition decision processes and system design refinement.
The Figure below is a template of SV-7, listing notional user defined performance characteristics with a time period association. It should be noted that these are example metrics.

It is sometimes useful to analyse resource evolution by comparing performance characteristics for current and future resources. For this reason, repository tools may produce hybrid SV-7 products which span architectures for multiple enterprise phases.
