It is a problem solving method that drives systemic change, improving an entire process in order to avoid not only the problem at hand but also other issues that may stem from a systemic failure.
8D has grown to be one of the most popular problem solving methodologies used for Manufacturing, Assembly and Services around the globe.
8D must always have two key members: a Leader and a Champion / Sponsor: D2: Describe the Problem The 8D method’s initial focus is to properly describe the problem utilizing the known data and placing it into specific categories for future comparisons.
The “Is” data supports the facts whereas the “Is Not” data does not.
D0: Prepare and Plan for the 8D Proper planning will always translate to a better start.
Thus, before 8D analysis begins, it is always a good idea to ask an expert first for their impressions.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.Activities in D5 include: D6: Implement and Validate the Permanent Corrective Action To successfully implement a permanent change, proper planning is essential.A project plan should encompass: communication, steps to complete, measurement of success and lessons learned.When properly applied, you can expect the following benefits: 8D was created to represent the best practices in problem solving.When performed correctly, this methodology not only improves the Quality and Reliability of your products but also prepares your engineering team for future problems.Activities in D8 include: The 8D process has Root Cause Analysis (RCA) imbedded within it.All problem solving techniques include RCA within their structure.
