PrVp-01 Procurement Structure

This page reproduces part of the PrVp-01 Procurement Structure architecture viewpoint definition from the specification - TRAK00001. TRAK. Architecture Framework. Viewpoints. The page content is therefore subject to the same GNU Free Documentation License terms and conditions - see https://www.gnu.org/licenses/fdl-1.3.html

Most of the content is produced from a model of TRAK produced using a different set of architecture viewpoints!

Version

The TRAK PrVp-01 Procurement Structure architecture viewpoint is one of 24 architecture viewpoints defined in TRAK00001. TRAK. Architecture Framework. Viewpoints - current release is dated 10 July 2024.

Summary

The TRAK PrVp-01 Procurement Structure architecture viewpoint defines the requirements for the TRAK PrV-01 Procurement Structure architecture view. This involves allowed content and minimum acceptable content ('well-formedness' criteria). The TRAK00001. TRAK. Architecture Framework. Viewpoints specification also defines consistency rules that apply to a set of architecture views (an Architecture Description).

The TRAK PrVp-01 Procurement Structure architecture viewpoint content is summarised under the following sections:

• stakeholder concerns
• description
• allowed content
• well-formedness criteria
• presentation methods
• examples
• views needed to construct
• consistency rules
• comments

The TRAK Architecture Viewpoints specification provides are complete definition not only of the PrVp-01 Procurement Structure architecture viewpoint but considerations for the architecture description formed from a set of architecture views.

Description

Describes the structural organisation for procurement of the solution(s).

Allowed Content

TRAK architecture view content is defined in terms of triples - Node - connector - Node e.g. 'Organisation governs Project' that form short statements about the thing(s) being described.

'Organisation governs Project' is a Statement or Assertion in a PrV-01 Architecture View

The rationale and theory for the allowed content of an architecture view is explained separately.

Subject Statements (Triples)

These are statements (triples) that describe the subject of the PrV-01 Procurement Structure architecture view. Specifically these statements address the concerns for this PrVp-01 Procurement Structure architecture viewpoint. These form the basis for the well-formedness section of the PrVp-01 Procurement Structure architecture viewpoint.

There are 2 possible subject statements in total which include 2 metamodel elements ( Organisation and Project ).

Return to the top of the Procurement Structure page.

Optional Statements (Triples)

These optional statements (triples) for the PrV-01 Procurement Structure architecture view provide useful context with respect to a subject or universally allowed statements involving the subject or object (start or finish) elements in the Subject Statements (triples).

Universal statements may be added to any TRAK architecture view and describe typical concepts such as compliance or traceability:

• ... traces to Argument, Contract, Requirement, Document or Standard
• ... satisfies Contract, Requirement, Document or Standard
• Concern or Claim about ...
• Contract, Requirement, Document or Standard governs ...

'Organisation traces to Standard' - an optional statement or assertion for the PrV-01 Architecture View

These statements address the concerns of their respective architecture viewpoint and will have been created first on these other architecture views.

There are 26 possible statements which may be used to augment the PrV-01 Procurement Structure architecture view, split into 5 groups:

• Universal - Applicable Requirements
• Universal - Assurance
• Universal - Concern Identified
• Universal - Requirement Compliance
• Universal - Traceability or Reference

Well-Formedness Criteria

This web site is a partial representation of the TRAK Architecture Viewpoints Specification

Well-formedness criteria define the minimum acceptable view content based on the subject statements (triples). These criteria are not included in this web page.

Please refer to the Well Formedness section within the PrVp-01 Procurement Structure architecture viewpoint definition in the TRAK00001. TRAK. Architecture Framework. Viewpoints specification (10 July 2024).

Presentation Methods

The PrV-01 Procurement Structure architecture view may use any of following means to the statements (triples):

• block diagram (Project, Organisation = block, TRAK relationship = line with direction indicator)

Note that a textual presentation is acceptable for any TRAK architecture view.

Examples

Example PrV-01 Procurement Structure Architecture View

UML implementation of a TRAK PrV-01 Procurement Structure Architecture View.

Note that an Organisation is not a Project - even if the part of an Organisation is named after the Project for which it is responsible for - a Project can be given to any organisation to deliver and therefore they are separate entities.

In the TRAK Metamodel specification (https://sf.net/p/trakmetamodel) they are defined:-

- Project - 'An individual or collaborative enterprise that is carefully planned and designed to achieve a particular aim.'

- Organisation - 'An organised body of people, associated for a particular purpose'.

Produced using (Sparx Systems Enterprise Architect UML modelling tool in conjunction with the MDG for TRAK plugin (https://sf.net/p/mdgfortrak.)

Views Needed to Construct

This web site is a partial representation of the TRAK Architecture Viewpoints Specification

Since a triple originates in a particular architecture view if there is a subsequent architecture view that uses the same triple it need not be created. Similarly you might wish to create a triple but in order to do so the node element has first to be created in its originating architecture view.

For example, you cannot describe the functionality of an element without first defining the element having that functionality. A Project Activity described using a PrV-02 architecture view needs a Project described in a PrV-01 architecture view.

These dependencies between architecture views create a natural sequence or order in which architecture views are created by virtue of their content. These criteria are not yet included in this web page.

Please refer to the Views Needed in Order to Construct section within the PrVp-01 Procurement Structure architecture viewpoint definition in the TRAK00001. TRAK. Architecture Framework. Viewpoints specification (10 July 2024).

Consistency Rules

This web site is a partial representation of the TRAK Architecture Viewpoints Specification

Consistency rules define rules applied to keep the collection of architecture views consistent and also to keep the logic formed by the statements using triples consistent. These criteria are not included in this web page.

Please refer to the Consistency Rules section within the PrVp-01 Procurement Structure architecture viewpoint definition in the TRAK00001. TRAK. Architecture Framework. Viewpoints specification (10 July 2024).

Comments

The PrV-01 Procurement Structure architecture view is the master source (origin) on which you first create the following elements or statements:

• Project

It does for Project what the SV-01 does for Resource in the solution perspective.

Neighbouring Architecture Views

The PrV-01 Procurement Structure architecture view content may overlap that of the following neighbouring architecture views:

• MV-01 Architecture Description Dictionary
• MV-02 Architecture Description Design Record
• MV-03 Requirements and Standards
• MV-04 Assurance
• PrV-02 Procurement Timeline
• PrV-03 Procurement Responsibility
