5.3 8 DISCIPLINE (8D)

5.3.1 Introduction to Eight Disciplines of Problem Solving (8D)

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.

Ford Motor Company developed this problem solving methodology, then known as Team
Oriented Problem Solving (TOPS), in the 1980s. The early usage of 8D proved so effective
that it was adopted by Ford as the primary method of documenting problem solving efforts,

and the company continues to use 8D today.

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.

5.3.2 What is Eight Disciplines of Problem Solving (8D)

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.

The strength of the 8D process lies in its structure, discipline and methodology. 8D uses a

composite methodology, utilizing best practices from various existing approaches. 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. Read on to learn about the reasons
why the Eight Disciplines of Problem Solving may be a good fit for your company.
