8 Steps Problem Solving

8 Steps Problem Solving-9
The root cause definition requires that it can be turned on or off, at will.

The steps and techniques within 8D which correspond to Root Cause Analysis are as follows: This example uses only 4 of the 5 Whys to determine the root causes without going further into the systemic reasons that supported the failure.

The Repeated Why is one way to depict this failure chain. Quality-One offers Quality and Reliability Support for Product and Process Development through Consulting, Training and Project Support.

The 8D process alternates inductive and deductive problem solving tools to relentlessly move forward toward a solution.

The Quality-One approach uses a core team of three individuals for inductive activities with data driven tools and then a larger Subject Matter Expert (SME) group for the deductive activities through brainstorming, data-gathering and experimentation.

8D has become very popular among manufacturers because it is effective and reasonably easy to teach.

Below you’ll find the benefits of an 8D, when it is appropriate to perform and how it is performed.After receiving feedback, the following criterion should be applied prior to forming a team: Collect information on the symptoms Use a Symptoms Checklist to ask the correct questions Identify the need for an Emergency Response Action (ERA), which protects the customer from further exposure to the undesired symptoms D1: Form a Team A Cross Functional Team (CFT) is made up of members from many disciplines.Quality-One takes this principle one step further by having two levels of CFT: Teams require proper preparation. Implementation of disciplines like checklists, forms and techniques will ensure steady progress.The Eight Disciplines of Problem Solving (8D) is a problem solving methodology designed to find the root cause of a problem, devise a short-term fix and implement a long-term solution to prevent recurring problems.When it’s clear that your product is defective or isn’t satisfying your customers, an 8D is an excellent first step to improving Quality and Reliability.Activities in D8 include: The 8D process has Root Cause Analysis (RCA) imbedded within it.All problem solving techniques include RCA within their structure.Activities in D6 include: D7: Prevent Recurrence D7 affords the opportunity to preserve and share the knowledge, preventing problems on similar products, processes, locations or families.Updating documents and procedures / work instructions are expected at this step to improve future use.The 8D problem solving process is a detailed, team oriented approach to solving critical problems in the production process.The goals of this method are to find the root cause of a problem, develop containment actions to protect customers and take corrective action to prevent similar problems in the future.
