5W2H Method. When starting an improvement initiative it is important to step back and reflect on your current situation. Use the 5W2H questions below to ensure. 5W2H is a tool that provides guiding questions when assessing a process or a problem, allow the questions and answers to lead you into cause analysis. 5W2H stands for 5 Ws and 2Hs or Who, What, When, Where, Whey How and How much. When working on improving a process this is a very.

Problem Solving instructs how to solve difficult problems using formal, documented techniques. If angles are missing, the reviewers can more easily see that a key factor was not considered. Return to Home page. Establish a small group of people with the knowledge, time, authority and skill to solve the problem and implement corrective actions. The ahalysis must select a team leader.

5W2H Method Used for Problem Solving – Latest Quality

Describe the problem in measurable terms. Specify the internal or external analhsis problem by describing it in specific terms. Be sure to cover 5W2H. Define and implement those intermediate actions that will protect the customer from the problem until permanent corrective action is implemented.


Verify with data the effectiveness of these actions. Define end Verify Root Causes. Identify all potential causes which could explain why the problem occurred. Test each potential cause against the problem description and data. Identify alternative corrective actions to eliminate root cause.

Confirm that the selected corrective actions will resolve the problem for the customer and will not cause undesirable side effects. Define other actions, if necessary, based on potential severity of problem.

Implement Permanent Corrective Actions. Define and implement the permanent corrective actions needed. Choose on-going controls to insure the root cause is eliminated. Once in production, monitor the long-term effects and implement additional controls as necessary. Modify specifications, update training, review work flow, improve practices and procedures to prevent recurrence of this and all similar problems.

Recognize the collective efforts of your team. Share your knowledge and learning.

Select the relatively narrow-focused theme for the problem solving. Collect and analyze data. Plan and Implement a solution. Reflect on process and next problem. As precisely as possible state the problem. Many factors materials, equipment, process, people, and environment can affect processes and create problems.

Consider all major categories of potential contributors. List probable reasons for the occurrence analyssi the problem action, inaction, presence, absence, state of being, on-going process. Collect data, which may analyis in the form of control charts, Pareto charts, etc. This data should then be analyzed objectively to determine likely contributors to the problem. Identify and communicate the causes for action to be taken. Determine what level action should be taken to prevent future occurrences, e.


Defining the criteria for successful action establishes the expected outcome for all concerned to agree upon. Often many solutions exist for a problem, defining them and listing the merits of all enables the best solution to be chosen.

5W2H Analysis

For problems with high impact or risk, parallel approaches may be required. Those solutions requiring significant resources should be discussed with management. Proper planning and execution are required to determine the efficacy of a proposed solution. Careful monitoring of the process is needed to determine if the root cause was identified and rectified.
