This section specifies the template risk.

NOTE  The template has been defined in the context of UK_Defence. Refer to the business context for details of related templates.

NOTE  An explanation of a template and the associated instantiation path is provided in the Template overview section.

Description

This template describes how to represent the concept of a risk in terms of PLCS model elements (templates, entities and reference data).

Business perspective

A risk is the definition of a chance or possibility of danger, injury to personnel, or loss of capability that has serious operational and/or financial consequences.

Business object definition

This information object represents the definition of a chance or possibility of danger, injury to personnel, or loss of capability that has serious operational and/or financial consequences.

Instance diagrams
The instance diagram in Figure  4 shows an example of the EXPRESS entities and templates that are instantiated by the template:
/risk(ALARP_Category='Tolerable', Context='#355', Description='fire causing loss of life', ID='R001', ID_source_organization='UK_Defence', Impact_Before_Mitigation='High_risk_impact', Name='fire death', Owner='#3', Priority='Medium_priority_risk', Probability_Before_Mitigation='5', Related_Support_Concept='#119', Related_Support_Solution='#37', Risk_of_ID='ev001', Risk_of_name='fire', Type='Safety_risk')/
(an illustration of the consolidated risk template is shown in Figure 5 below.)

The instance diagram in Figure 5 shows the graphic symbol for the template that is to be used in other instance diagrams. The example template is:
/risk(ALARP_Category='Tolerable', Context='#355', Description='fire causing loss of life', ID='R001', ID_source_organization='UK_Defence', Impact_Before_Mitigation='High_risk_impact', Name='fire death', Owner='#3', Priority='Medium_priority_risk', Probability_Before_Mitigation='5', Related_Support_Concept='#119', Related_Support_Solution='#37', Risk_of_ID='ev001', Risk_of_name='fire', Type='Safety_risk')/

Characterizations
No common characterizations of the template risk have been identified. However, the ISO 10303-239 EXPRESS model may enable other assignments to the entities instantiated by the template.
