Looks at the introduction of statistical process control (SPC) into a distribution center servicing a department store chain. Focuses on the receiving process in the distribution center and describes the introduction of SPC methodology. Discusses run charts, pareto diagrams, and control limits.

To introduce statistical process control.

Assumes an understanding of statistical process control and focuses on highlighting the usefulness of Six Sigma quality. Focuses on the issue of a worn bearing at a tire manufacturer leading to a mean shift (while producing defectives). Shows how a Six Sigma process would quickly detect the mean shift while producing fewer defectives.

To introduce the methodology of statistical process control and to illustrate the value of Six Sigma.

Alan Silko must decide whether to invest in seven statistical-process-control (SPC) stations in order to increase his chances of becoming a “select supplier” for a large computer company.

Continuous process improvement has been widely taught in business schools and has yielded real results and success in both for-profit and non-profit sectors. Though there have been many cases developed for use in business schools, few, if any, situate the topic in a military context. Further, expeditionary logistics presents managers with special problems of being removed from their supporting enterprise systems that process, track, and/or control of such logistical elements as purchase orders, inventory, distribution, receivables, and fulfillment. The authors present a case in a military setting that exposes students to the challenges of expeditionary logistics and takes them through the fundamentals of process analysis and process improvement.

The authors used a research methodology of a case study. Data were collected during field visits over the course of multiple interviews. Interviews were conducted with subject matter experts and active professionals serving in US Navy expeditionary logistics roles regarding processes and process performance.

This case can be applied to senior undergraduate or graduate-level courses in operations management, supply chain management, or logistics.

The theoretical bases adopted in this paper are supply chain management, information technology, operations management, and process improvement methodologies such as Six Sigma and Lean.

Republic Electric is faced with the need to engage in a systematic process of evaluating vendors for its just-in-time manufacturing. The case gives students the opportunity to think through the process for vendor selection in the context of real-world constraints for a specific organization, to become acquainted with the Delphi technique for developing consensus, to gain hands-on experience with linear averaging, to engage in calculations of value indexes, and to recognize the marketing implications of effectively evaluating vendors. A key takeaway for students is the fact that vendor selection decisions are multifaceted and will vary among organizations depending on each organization’s particular strategic needs, operational constraints, and human judgment.

The case is based upon a consulting assignment with the company that is represented by Republic Electric. The experience was gained first-hand by one of the authors.

This case is targeted at undergraduate students in marketing, materials management, supply chain management, and purchasing, but can work well in a variety of business courses in which supply chains or the development of evaluation tools is studied, to include graduate classes.

The concept of vendor assessment is well developed in the literature and represents a pragmatic, but often neglected, step in the practice of choosing suppliers.

Quality management among multiple business units of a large organization is often difficult if each unit is run independently in terms on their quality standards. In this case, participants will discuss how Bukhari Group of Companies should establish a common brand image through standardized quality. Participants should also understand that common brand image for diverse products does not mean identical level of rejection or customer complaints. It should be understood that different markets have different tolerance for product failures. The participants can chalk out the measures the protagonist of the case should be able to take to effectively steer the Bhukari Group to achieve profits and excellence.

This case study deals specifically with the issue of manufacturing strategy, and business strategy.

It can also be assigned for an in-depth treatment of manufacturing strategy.

The case focuses on Capital Mills Limited (CML), a flour milling company, and concentrates on whether the company should refurbish its two 40-year old flour mills at a cost of US$6 million or if the company should invest US$15 million in the construction and installation of a new, fully-automated “Lights out” flour mill. This decision is viewed as a “make or break” decision for CML, since for the first time in the company's 40 year history will it face significant direct competition, in the form of the impending entry of a second flour milling company.

The case has four primary learning objectives, namely to: illustrate the linkages between business level strategy and the functional level, manufacturing strategy; discuss the role of a company's history and internal resource structure in the decision making process; explore how operational issues influence capital expenditure decisions; and explore the perspective of managers in different functions in an organization that is facing a new competitive challenge.
