6.6 Chapter Summary & Review
Summary
Chapter 6, “Managing Quality,” delves into the critical aspects of ensuring quality in products and services. It begins by defining quality from the consumer’s perspective, emphasizing that a product’s success hinges on meeting or exceeding customer expectations. This chapter highlights the historical shift towards quality in operations management, particularly noting how Japanese manufacturers set high standards that North American companies had to catch up with. It distinguishes between design quality, which focuses on the product’s inherent characteristics, and process quality, which ensures that manufacturing processes consistently produce defect-free products.
The chapter also introduces several key figures in the field of quality management, known as the quality gurus. These include Walter Shewhart, who pioneered statistical quality control; W. Edwards Deming, whose principles transformed Japanese manufacturing; Joseph Juran, known for the Juran Trilogy; Philip Crosby, an advocate for “zero defects”; and Armand Feigenbaum, who developed the concept of total quality management (TQM). Each guru’s contributions helped shape modern quality management practices, emphasizing continuous improvement, customer satisfaction, and employee involvement.
Moreover, the chapter outlines various quality systems and methodologies such as TQM, ISO standards, and Six Sigma. It discusses the costs associated with maintaining quality, categorized into prevention, appraisal, internal failure, and external failure costs. Additionally, it describes quality improvement tools like check sheets, histograms, Pareto charts, scatter diagrams, cause and effect diagrams, and control charts. By implementing these tools and adhering to established quality frameworks, organizations can effectively monitor, control, and enhance their processes, ultimately leading to higher customer satisfaction and operational efficiency.
