SVp-04 Solution Function Viewpoint

Version

7

Date

11th April 2011

Overview

The SVp-04 Solution Function Viewpoint is part of the TRAK Solution Perspective and one of the 21 TRAK Architecture Viewpoints.

The SVp-04 describes the functionality or behaviour of the solution and its component parts.

The SVp-04 architecture viewpoint is the specification for the TRAK::SV-04 Solution Function architecture view.

Stakeholders Addressed

• Owner of Solution
• Acquirer of Solution
• Developer of Solution
• Trainer of Solution
• Operator of Solution
• User of Solution
• Maintainer of Solution

Concerns Addressed

Have all solution functions been identified? What does each part do?

Description

Describes the functions of parts of the solution.

Covered by TRAK IPR and licenses

Mandatory Tuples

At least:

• Resource performs Function
• Function has part Function

where Resource = System, Physical, Software, Organisation, Job or Role

• Function has part Function
• Function is quantified by Metric
• Metric has part Metric

Optional Metamodel Elements

Universal

• Concern about Architecture Description Element
• Architecture Description Element traces to Document
• Standard governs Architecture Description Element
• Architecture Description Element traces to Requirement

If any of these optional metamodel elements are added then the appropriate TRAK Master Architecture View must be provided.

If any of these optional metamodel elements are added then the appropriate TRAK Master Architecture View must be provided.

Well-Formedness

A SV-04 view shall contain:

• at least 1 Resource (the subject of the view)
• the subject Resource must have at least 1 Function

Presentation

• block diagram (Resource, Function = block, TRAK relationship = line with text label and direction indicator)

Views Needed to Construct

• SV-01 Solution Structure View (specified by viewpoint SVp-01) - master architecture view for Resource (Job, Physical, Organisation, Role, Software, System)

See Minimum Allowed View Sets

Covered by TRAK IPR and licenses

The SV-01 is the source for the definition of the solution structure.

Consistency Rules

• Resource must appear in SV-01 Solution Structure View
• Functional Realisation of Node.: IF {Node conducts Concept Activity (CV-05)} AND {Resource performs Function realises (same) Concept Activity (SV-04 + SV-05) } THEN {Resource realises Node} must be made on the SV-01.

Further rules are applied through the TRAK Bye Laws

Configuration History

The TRAK Viewpoints project on Sourceforge (trakviewpoints.sourceforge.net) maintains a version-controlled repository. The change record is at trakviewpoints.svn.sourceforge.net/viewvc/trakviewpoints/trunk/?view=log

Comments

The SV-04 is the master architecture view for Function.

Any ordering of functions is shown using the Solution Sequence View - SV-07.
