Root cost analysis

RCA helps pinpoint contributing factors to a problem or event RCA helps organizations avoid the tendency to infourok net out one factor to arrive at the most expedient but generally incomplete resolution. Some methods used in RCA include:. The team should also determine a Verification or Validation Plan.

The following information must be determined and documented:. Next, the team may want to collect data or other additional information. It may also be necessary to initiate interim containment or corrective actions. The team should review all gathered information and further define the problem. The problem should be defined based on facts and data. Once the problem is fully described the team can then begin the Root Cause Analysis phase.

The Team should be comprised of personnel that have direct knowledge of the process being examined and responsibility for implementing any permanent corrective actions. In addition, the team should include representatives from Quality, Process Engineering and, when appropriate, team members from the next step in the process or from other shifts.

Each member of the CFT will bring their own knowledge and view of the process and the non-conformance. There are multiple tools that could be utilized during a Root Cause Analysis. This section will cover some of the tools including how and when they could be of value to the analysis.

It can be used while defining the problem to determine what is in scope and will be considered during the analysis and what is out of scope and will not be considered. It can also be used when planning a solution, to help the team decide what to include and what to exclude. The Is-Is Not analysis allows the team to think about the problem and the boundaries of what it is or is not.

The tool helps the team maintain their focus. If the boundary of the problem is not clearly defined the team may stray off the initial path and work on solving inconsequential problems. The process works by asking the team various questions such as:. The diagram is sometimes referred to as a Fishbone Diagram because it looks much like a skeleton of a fish with the effect or problem being listed in a box at the end. It is important not to limit the teams brainstorming ideas here.

If an idea is in a different section of the diagram, simply list it in the appropriate section and then go back to it later. Once the team has brainstormed all the possible causes of the problem, the team should rate the potential causes according to their level of importance and likelihood of contributing to the failure and develop a hierarchy.

From the hierarchy the team should select which causes to further investigate. The 5 Whys is often used during the problem solving activities. It is also used in coordination with other analysis tools, such as the Cause and Effect Diagram, but can also be used as a standalone tool. The 5 Whys is most effective when the answers come from people who have hands-on experience of the issue being examined.

Each area should be explored and you may have more than one causal progression for each area. In many companies if a major problem is detected in the process or product, the team is required to review any existing FMEAs in relation to the problem. The team should determine if the problem or effect of the failure was identified in the FMEA and if it was, how accurately the team evaluated the risk.

If the problem is not included in the FMEA, the team should add any known information and then complete the following steps:. Once the team has determined the root cause using any combination of the tools listed above then they must develop the appropriate counter-measures or corrective actions. In addition, the team should develop an action plan for implementation of the counter-measures. The corrective action must be clearly defined and achievable by the team member assigned to complete the task.

The action plan should also contain expected due dates for each of the corrective actions. It is often discovered that corrective actions without an owner or an expected due date seldom get completed. Occasionally the counter-measures require tasks to be completed by more than one of the team members simultaneously or in a certain order.

The action plan should be used to track progress of individual action items required to complete implementation of the countermeasures. The team should also determine a Verification or Validation Plan. This is used to provide a documented performance appraisal of the counter-measures effectiveness. This could entail recording data or auditing any special controls developed and implemented during the RCA exercise. Evidence should be collected to verify the effectiveness of the counter-measures or corrective actions.

In addition, it is good practice to re-assemble the team approximately 30 days after the permanent counter-measures are in place. The team should review the effectiveness of the counter-measures and determine if the problem has occurred since implementation of the counter-measures.

The team should also review the process if applicable to assure all counter-measures are being followed. The development of a robust, well-planned Root Cause Analysis RCA process can be very valuable to the company by determining the root cause and taking action to prevent it from re-occurring. The lessons learned during an effective RCA can often be carried over to similar designs or processes.

This should initiate a problem solving continuous improvement mind-set to spread throughout the company. Root Cause Analysis Diagram. The root cause is the core issue that sets in motion the entire cause-and-effect reaction that ultimately leads to the problem s. Some root cause analysis approaches are geared more toward identifying true root causes than others, some are more general problem-solving techniques, and others simply offer support for the core activity of root cause analysis.

Root Cause Analysis for Beginners Article. Root cause analysis can be traced to the broader field of total quality management TQM. TQM has developed in different directions, including a number of problem analysis, problem solving, and root cause analysis. It must be made part of a larger problem-solving effort for quality improvement. There are many methodologies, approaches, and techniques for conducting root cause analysis. A U. Department of Energy guideline lists the following five:.

There are many benefits to implementing root cause analysis. Continue your learning with the articles, books, courses, and other resources on root cause analysis listed below.
