Setting Risk Analysis Options for a SIF Analysis

This topic explains how to set the risk analysis options for a SIF analysis. If the analysis uses an analysis type, the risk analysis settings are copied from the analysis type. You can review and change them as required.

To Set Options for Using Embedded Evaluation Forms

1.
Open the Strategy Development Analysis window.
2.
Make sure that editing is enabled.
3.
On the Properties view, select the Risk Options tab.
4.
Click Use embedded evaluation forms.
On the General tab, By failure mode is selected by default.
5.
Set the following options:
Setting Name
Description
Risk matrix
The risk matrix specified as the default for risk analyses of this type. The matrix displays the results of the failure mode’s probability and severity evaluations, as well as its relative risk (criticality).
Safety provision is required when the risk level is or exceeds
When the evaluation results in a risk level at or above this value, the analysis team must add a safety provision to reduce the risk level. In this box, specify the SIL value that cannot be exceeded.
The failure mode cannot be marked “Facilitation Complete” or “Implementation Complete” until the risk level is below this threshold.
Safety mitigated risk cannot exceed
When the evaluation results in a mitigated risk level greater than this value, the failure mode cannot be marked “Facilitation Complete” or “Implementation Complete”. The analysis team can add one or more safety provisions to reduce the risk level.
In this box, specify the SIL value that cannot be exceeded.
6.
Select the Probability tab.
7.
Set the following options:
Setting Name
Description
Evaluation performed
When selected, this option allows the evaluation to be performed.
Use of evaluation questionnaires is allowed
When this option is selected, analysts can fill in an online form.
Evaluation form
Evaluation form that analysts use to perform the assessment.
Evaluation type
Evaluation forms can have these types:
•
Simple – The evaluator can select one statement for each category on the form.
•
Detailed – The evaluator can select two statements for each category on the form.
Use of evaluation buttons is allowed
When this option is selected, analysts can simply click the button that represents the result of their evaluation.
Score set to use
A score set assigns scores for each of the appropriate failure probabilities or consequence severities. Score sets make it possible to evaluate assets based on their material types or other characteristics.
8.
Select the Economic tab.
9.
Set the following options:
Setting Name
Description
Evaluation performed
When selected, this option allows the evaluation to be performed.
Evaluation form
Evaluation form that analysts use to perform the assessment.
Risk relevant
When selected, this option ensures that the evaluation is available in the risk analysis.
10.
Select the Health and Safety tab.
11.
Set the following options:
Setting Name
Description
Evaluation performed
When selected, this option allows the evaluation to be performed.
Use of evaluation questionnaires is allowed
When this option is selected, analysts can fill in an online form.
Evaluation form
Evaluation form that analysts use to perform the assessment.
Evaluation type
Evaluation forms can have these types:
•
Simple – The evaluator can select one statement for each category on the form.
•
Detailed – The evaluator can select two statements for each category on the form.
Score set to use
A score set assigns scores for each of the appropriate failure probabilities or consequence severities. Score sets make it possible to evaluate assets based on their material types or other characteristics.
Economic impact to use
The type of values used in the evaluation for the economic impact, for example, standard values or alternates.
Risk relevant
When selected, this option ensures that the evaluation is available in the risk analysis.
12.
Select the Environmental and Reputation tabs in turn and set the options for using evaluation questionnaires and buttons.
13.
Select the Risk Plot tab. The risk plot chart can show either a single risk tolerance line or colored areas for one or more risk levels.
14.
Select the appropriate option:
•
Risk plot uses a single risk line – risk plot chart displays a line to indicate the failure mode’s initial risk. Select the chart line style from the list, for example, “FM risk tolerance line”. Here is an example of a risk chart with a single line:
•
Risk plot uses areas to show risk – Each severity level is represented by a colored area in the chart. The window changes as follows:
Select the appropriate chart line style for each risk level that you wish to show. Here is an example of a risk chart with all five areas:
