Root Cause Analyses Process

To implement the RCA functionality, you must select the Root Cause Analysis Implemented check box in Quality Management Parameters (qmptc0100m000) session. You must specify these data related to the root cause analysis document (RCA) series:

  • Number Group
  • Default Series
  • Use Action Category

You must specify the action to be performed using the Action Category field in the Task Types (qmcpl0101m000) session. You can select action such as Containment, Corrective, Preventive or General. You must select the action category based on the type of action, For example: If the task is of the type Containment, the category must be set to Containment.

The process to execute the root cause analysis for problem solving:

Step 1. Forming the Team

Set-up a cross functional team for problem-solving process. You must specify the list of employees for each corrective action plan in the Members by Review Board, Document (qmcpl1101m000) session. You can also use this session to maintain the list of employees to be associated with the review board responsible for reviewing the progress of the Corrective Action Plan (CAP).

Step 2. Defining the Problem and analysing the problem

Define the problem for which the root cause analysis is performed. You must specify the information related to the problem in the Corrective Action Plan (qmcpl1100m900) session.

You can perform a detailed analyses of the problem to arrive at a problem statement using the Problem Analysis (qmcpl1102m000) session to define the problem related to the Corrective Action Plan (CAP). You can analyze the problem using the questions, listed in the Specify the Problem field.

Step 3. Performing Interim Containment Action (if required)

Create a task in the Corrective Action Plans - Tasks (qmcpl1605m000) session with Action Category set to Containment.

Step 4. Performing Root Cause Analysis

Generate the root cause analysis document from the Corrective Action Plan (qmcpl1100m900) session. You can use the Create Root Cause Analysis option to generate the Root Cause Analyses document using these methodologies:

  • Root Cause Analysis - 5 Why: Use the Root Cause Analysis-5Why (qmrca1100m100) session to specify the 5Whys that can help evaluate the root cause of the problem. You must specify the Why's till you identify problem and drill down to the root cause. The list of questions (5WHY's) enable you to :
    • understand the reason for the occurrence of the problem
    • detect the cause of the problem.
    • Analyse the reason for the failure of the possible measure.
  • Fishbone - Cause Category and Root Cause Analysis: Use the Fishbone Cause Category (qmrca0101m000) session to define the category of cause of the problem such as material, machine or environment. This category can be used to analyze the likely cause and the root cause of the problem, using the fishbone problem solving methodology. You can use Root Cause Analysis - Fishbone (qmrca1100m200) session to view and maintain the data related to the Root Cause Analysis (RCA) performed using the fishbone method. You can define the causes and sub-causes of the problem.
  • Root Cause Analysis - Checklist: Use the Root Cause Analysis - Checklist (qmrca1100m300) session to view and maintain the checklist for the problem solving. You can list the probable questions and the response (reason) to identify the root cause.
Step 5. Defining Permanent Corrective and Preventive Actions plans and Verifying the results

Define the permanent corrective actions and a verification plan on the Verification of CAP tab in the Corrective Action Plan (qmcpl1100m900) session. The Effectiveness of CAP is Verified check box indicates that the CAP is effective.

You can generate the A3 and 8D problem solving report using the Print Corrective Action Plans (qmcpl1400m000) session.
