Investigation analysis

Edit online

Following an investigation, you can do an analysis of your data to prevent or minimize the impact of future similar defects and incidents.

By using the Analysis tab on the Investigations application, you can record the following details:

Root Cause Failure Analysis (RCFA) Results

On the RCFA Results subtab, you can record a summary of your RCFA results. For example, you can specify whether the root cause was identified and whether any follow-up actions were essential. You can also create the following records directly from the Cause field:
  • Service request
  • Investigation
  • MOC request
  • Action

Cause Analysis

The Cause Analysis subtab supports a five Whys type of cause analysis where you ask several why questions to establish the root cause of a failure. If essential, you can build a structure that contains multiple root causes.

Human Factors

On the Human Factors subtab, you can list and categorize, the human, and systemic, factors that might have contributed to the root cause of the incident. You can also specify whether any follow-up actions or improvements are essential.

On the List tab of the Investigations application, you can use the Add/Modify Human Factors Categories action to update the default categories as needed.

Structured Root Cause Analysis (RCA)

On the Structured RCA subtab, you can enter the details and results of your structured RCA. With this capability, you can do an analysis that is based on a hierarchy of predetermined causes. Before you can enter the results of your RCA, your administrator must first define the hierarchy for the structure.

Failure Mode, Effects, and Criticality Analysis (FMECA)

On the FMECA subtab, you can record the details of your FMECA. You can specify the failure modes that were identified during an investigation, and you can create the following records directly from the Failure Mode Number field:
  • Service request
  • Investigation
  • MOC request
  • Action
When you create a follow-up record, the investigation is listed as a related record on the follow-up record.

You can also create a Reliability Centered Maintenance (RCM) type of analysis for multiple assets or locations. The investigation record acts as the parent record that pulls together all of the FMECAs that were carried out at a location or asset level.
