Article Abstract

The work of a "Juran team" set up to solve a quality problem that was costing the company tens of thousands of dollars annually in scrapped nickel-cadmium cells is described in this case study. The team used a Pareto chart to determine the two most common forms of the problem, an Ishikawa cause-and-effect diagram to determine the best way to manufacture the item. The study resulted in a production process with almost zero defects, a savings of tens of thousands of dollars annually, an improved quality reputation and higher worker morale.
