A recall also results to lost income for retailers, who have to pull the product from their shelves. The entire supply chain is impacted by a quality failure as the company figures out whether they will change the product or discontinue it.

The goal of SPC is to ensure that production operates at its full potential. <strong>Full potential<\/strong> is the point where the process produces the maximum amount of conforming product as possible with a minimum (if not the total elimination) of defective parts, rework, or scrap. SPC can be applied to any process in which the product can be measured. Key tools used in SPC include control charts with a focus on continuous improvement.<\/p>\r\n<h2>Benchmarking<\/h2>\r\n<p><strong>Benchmarking<\/strong> involves comparing one business' processes and performance metrics to industry bests and best practices from other companies. Dimensions typically measured are quality, time, and cost. In the process of best-practice benchmarking, management identifies the best firms in their industry\u2014or in another industry where similar processes exist\u2014and compares the results and processes of those studied (the \"targets\") to their own results and processes. In this way, management learns how well the targets perform and, more importantly, the business processes that explain why those other companies are successful.<\/p>\r\n<p>Benchmarking is used to measure performance using a specific indicator (cost per unit of measure, productivity per unit of measure, cycle time of x per unit of measure or defects per unit of measure) resulting in a metric of performance that is then compared to others. Benchmarking may be a one-time event but is often treated as a continuous process in which organizations continually seek to improve their practices.<\/p>\r\n<section class=\"textbox tryIt\">[ohm2_question height=\"350\"]4334[\/ohm2_question]<\/section>\r\n<\/div>","rendered":"<section class=\"textbox learningGoals\">\n<ul>\n<li>Recognize different ways to ensure high quality goods and services<\/li>\n<li>Recognize the benefits of national and international quality standards<\/li>\n<\/ul>\n<\/section>\n<h2>Quality Assurance<\/h2>\n<p>What is <em>quality<\/em>?
