C5 — Effects

Purpose & Usage

The C5 Viewpoint is concerned with identifying and describing desired effects of Capabilities and the Effectiveness Criteria that are specified for them.

• Operational Analysis.
• Analysis of non -functional properties.
• Characterization of the expected results capabilities, noting that effects can be positive or negative.
• Analysis of cumulative effects.
• Analysis of persistence of the effects.
• Tracing the operational states and modes with regards to the effects.

Scope

• Shall contain Effects that the Capabilities desire.
• May show Effectiveness Criteria that is specified by Capabilities.
• May show Effectiveness Criteria characterizing the Effects.
• May show measures that evaluate the Effectiveness Criteria.

Representation

• Tabular.
• Structural diagram.
