Five Steps to Improved Manufacturing Quality

     

    Good managers seek to contain costs in the manufacturing environment. There is no better cost to eliminate than the cost of poor quality.  Scrap material and lost labor hours add no value to the operation.  In order to best eliminate these wastes, a strategic approach to quality improvement is essential.  By following these five steps, quality can be improved in a meaningful, sustainable way.

     

    1. Use a Team-Mindset

     

    Quality won’t be sustainably improved by individuals. To really make lasting and meaningful change in manufacturing processes, it will take a team based approach.  By involving multiple disciplines in the search for improved quality, a variety of perspectives is obtained.  Of importance is also knowledge of process history.  Why is the process the way it is today?  There must be a reason or cause and that reason should be considered so as not to repeat a problem of days gone by.  By considering history and group perspective, solid improvements can be obtained.

     

    1. Define Quality from the Customer Perspective

     

    Too often, staff within a manufacturing environment want to make a product “better” but don’t really know what better means. With additional cost, we can almost always make a product better.  But is additional cost desirable by the customer even if it means better product life?  Someone in the organization should serve as the customer advocate.  Typically this voice can come from the Sales or Marketing departments.  Use the customers’ perspective to define what the best-in-class product would be and meet those requirements while minimizing cost.

     

    1. Develop Organizational Understanding of the Cost of Quality

     

    The cost to fix a defect in the field once it reaches a customer is dramatically higher than the cost to fix the source of the problem before it is created. It is essential that the manufacturing staff be trained to understand the cost multipliers involved with warranty repair or replacement and cost of damaged reputation.  Once the staff take this perspective, a desire to find root cause for problem solving is inherently developed.

     

    1. Solve problems completely

     

    All too often, manufacturing quality improvements fix the symptoms of failure rather than the root cause. This can be done by adding quality inspection steps or rework stations that make it more efficient to fix defects.  Instead, a true understanding of root cause should be developed within the teams.  When they develop the ability (through Ishikawa, fault tree, or five-why analysis) to ascertain root cause of defects in the manufacturing process along with a “killer test” that verifies the ability to turn-on and turn-off the problem in the manufacturing process, true solutions to problems will be created that will not allow the return of the issue.

     

    1. Employ Strong Process Discipline

     

    Throughout the quality improvement process, it is essential that strong process discipline is employed. Depending on the product that is being manufactured, deviation without proper team cooperation and anticipation of the change could have dire quality repercussions.  While the organization should avoid cumbersome bureaucracy that inhibits innovation, it is essential that some structure be employed to maintain consistency and an understanding of the way the product is produced during that time period so that root cause can also be identified later if new problems arise as a consequence of the change.

      

    By following these five steps, good management teams can develop great quality programs within their organizations.
