BRAINSTORMING Brainstorming is a simple technique for gathering the ideas for developing creative solutions to problems.
Brainstorming helps you to have diverse experience of all team members into play during problem solving and/or solution development.
AFFINITY DIAGRAM The affinity diagram, also known as the KJ method was developed by Dr. This diagram gathers together items, needs or features of similar types.
It is applied in conjunction with cause-effect diagram for quality design and quality improvement processes.
The 5 Why exercise can be used as a stand- alone tool or applied within a larger problem solving activity.
5 Why is commonly used during the Analyze phase of the DMAIC process and the Plan phase of the PDCA process.The following is a sample list with a brief description of each method.5 Why is a problem solving method that asks the question “Why” enough times until you get down to the root cause of a problem.This increases the confidence and self satisfaction to all team members and a feeling of ownership of the problem which will also help to find better solutions to the problems you face.Please click to download the full technical document.They are tools required to facilitate the process of problem solving, including root cause analysis and corrective action.IS – IS NOT “IS – IS NOT” is a problem solving tool that explain the rational process for finding the possible root cause of the problem.Deming always referred to it as the “Shewhart cycle”, PDSA (Plan-Do-Study Act).Deming modified it to PDCA because he felt that “check” emphasized inspection over analysis.Customers could determine that your organization is not capable of resolving problems within your products or processes.There are many problem solving tools and approaches that are all effective if used properly.
