2001 "Root Cause Analysis" Survey Results

Ó Plant Maintenance Resource Center

Overview

This survey of use of Root Cause Analysis techniques by Maintenance professionals was conducted on the Plant Maintenance Resource Center web site in late 2000.

Summary of Key Findings

Voluntary (and confidential) responses were sought to the survey, and 146 valid responses were received from a wide range of individuals working across a variety of industries.

The key findings are:

  • 59% of respondents indicated that they used some form of Root Cause Analysis process
  • Of those who indicated that they used some form of Root Cause Analysis process, 79% indicated that they used formal, structured processes
  • Those using formal processes considered that the overall effectiveness of their approach was significantly better than did those people using informal processes.
  • Supervisory and technical staff are more likely to be involved in Root Cause analysis than shop floor personnel.
  • The greatest benefits appear to be in the area of improved Equipment Availability and Reliability, but users of Root Cause Analysis processes reported benefits across a wide range of parameters.
  • 60% of respondents indicated that they used external consultants to assist with their Root Cause Analysis implementation, and those that used external consultants were slightly more likely to report that their Root Cause analysis process was more effective
  • 55% of respondents indicated that they used software to assist with their Root Cause Analysis process, and those that used software were significantly more likely to report that their Root Cause analysis process was more effective
  • 59% of respondents used the TapRooT approach to Root Cause analysis
  • Most of those that used commercially available approaches considered these approaches to be effective, but those that used other approaches were less satisfied with the effectiveness being achieved.
  • Significantly, 25% of all respondents indicated that they were considering implementing a new or revised Root Cause approach.

When is Root Cause Analysis used?

From the data provided, it would appear that significant, "one-off" events, are investigated slightly more frequently than recurring, frequent events using Root Cause Analysis. However, events that lead to Safety or Environmental consequences are significantly more frequently analysed using Root Cause Analysis processes, than are those events which lead to lost Production, which in turn, are generally more frequently analysed than those events which lead to increased costs.

Which "One-off" events are analysed using Root Cause Analysis processes?
  Production Loss Safety Incident Environmental Incident Operating Cost increase Maintenance Cost Increase
Always 33% 64% 52% 17% 14%
Often 35% 23% 21% 21% 21%
Sometimes 20% 8% 13% 43% 4%

Who participates in the Root Cause Analysis process?

Maintenance personnel, on the whole, tend to be more involved in Root Cause Analysis processes than Production personnel, and supervisory and technical staff are more likely to be involved than shop floor personnel.

55% of respondents indicated that they used software to assist with their Root Cause Analysis process

Do you use specialist Root Cause Analysis software to support your Root Cause Analysis process?
Response Number % of Total
Yes 47 55%
No 37 43%
N/A 2 2%

Those that used specialist Root Cause Analysis software were significantly more likely to report that their Root Cause analysis process was more effective

Root Cause Analysis approaches used

59% of respondents used the TapRooT approach to Root Cause analysis

Is your Root Cause Analysis process based on any of the following commercially available Root Cause Analysis processes?
Response Number % of Total
Apollo 3 3%
ProAct 3 3%
Reason 2 2%
TapRooT 51 59%
Inhouse System 12 14%
Other Approach 4 5%
Don't Know 4 5%
Don't Know 7 8%

Most of those that used commercially available approaches considered these approaches to be effective, but those that used other approaches were less satisfied with the effectiveness being achieved. In interpreting the following table, be aware that the total number of respondents using Apollo, ProAct and Reason was very small.

Approach Used Overall, how would you rate the effectiveness of your Root Cause Analysis process?
Excellent Very Good Good Satisfactory Poor Don't Know N/A
Apollo 25% 50% 25% 0% 0% 0% 0%
ProAct 0% 33% 67% 0% 0% 0% 0%
Reason 0% 50% 0% 50% 0% 0% 0%
TapRooT 23% 46% 21% 10% 0% 0% 0%
Inhouse System 0% 31% 8% 46% 15% 0% 0%
Other Approach 0% 25% 25% 25% 25% 0% 0%

Considering a New/Revised Root Cause approach

Significantly, 25% of all respondents indicated that they were considering implementing a new or revised Root Cause approach. This is made up of 22% of those that are currently using Root Cause approaches, and 30% of those that are not currently using Root Cause approaches. It would appear that, although most respondents reported significant benefits with using their existing Root Cause Analysis approach, they feel that there may be improvements that can still be made.

Is your workplace currently considering implementing a new/revised Root Cause Analysis process?
Response Number % of Total
Yes 37 25%
No 73 50%
Don't Know 14 10%
N/A 22 15%

The decision regarding whether to consider alternative approaches appears to be relatively independent of the approach being currently used, although those using self-developed approaches appear to be more likely to be investigating alternatives. In interpreting the following table, be aware that the total number of respondents using Apollo, ProAct and Reason was very small.

Is your workplace currently considering implementing a new/revised Root Cause Analysis process?
Current approach used Number of Responses % of Total
Apollo 1 25%
ProAct 0 0%
Reason 0 0%
TapRooT 10 19%
Inhouse System 5 38%
Other Approach 1 25%
