This case study presents CoolKast, a leading household appliance company, which focuses on problems in the assembly line of new refrigerators. The refrigerator plant keeps a record of all the quality problems reported within the organization and its customers.

Part A of the case study concentrates on current issues that involve a lack of attention to quality, inadequate production planning, and a failure to communicate and engage with employees. Quality procedures for past products and new products on the line are discussed in detail. There are concerns regarding the cost and improving the quality of the production processes. The quality control, process, and maintenance teams should address the underlying problems in the assembly and manufacturing of the refrigerators, especially with respect to the process of inserting foam into the refrigerators.

Part B of the case study presents data on the foaming process for the refrigerators in order to identify areas and evaluate root causes in the foaming process for these refrigerators.
