Service Performance Metrics $5.00 Buy Now
This paper defines the service performance metrics for both manufacturing and service organizations. Service metrics in manufacturing include metrics for (1) make-to-stock products, (2) respond-to-order (make-to-order, assemble-to-order, etc.) products, and (3) pure services. The paper presents and evaluates all of the major metrics for each of these three business contexts. Examples are provided for each type of metric. The paper then explores measures of customer satisfaction such as the Net Promoter Score (NPS), the Customer Effort Score (CES), and the Word of Mouth Index (WoMI).

The Better-Faster-Cheaper-Strong Framework $5.00 Buy Now
Most instructors, students, and managers struggle to build a simple framework for the supply chain and operations management discipline. Although most standard texts offer some type of framework, none of these has been widely accepted. This short tutorial presents Professor Art Hill’s successful “Better-Faster-Cheaper-Stronger” framework for teaching the supply chain and operations. He developed this framework over many years of teaching the core MBA supply chain & operations course at the University of Minnesota and at IMD International. The “Better-Faster-Cheaper-Stronger” framework is process-focused rather than functional-focused and is based on the following four fundamental premises: (1) all work is a process, (2) all processes can be improved, (3) processes are improved by making them better, faster, cheaper, and stronger, and (4) improved processes can add more value to the world.

The Economic Lot Scheduling Problem $5.00 Buy Now
A paper that presents a model for the economic lot scheduling problem. The economic lot scheduling problem (ELSP) is a type of lotsizing problem that involves finding the optimal (or near optimal) order size (or cycle length) in order to minimize the sum of the carrying and ordering (setup) costs for multiple items that share the same capacity (the “bottleneck”). Even though the problem has the word “scheduling” in its name, it is really a lotsizing problem rather than a scheduling problem. The demand for each item is assumed to be constant.

The Hypergeometric Distribution $5.00 Buy Now
This paper presents the hypergeometric distribution, an important (but often neglected) discrete probability distribution found in a wide variety of contexts. The paper develops the mathematics for the distribution and provides several numerical examples. The paper also presents the statistics for the distribution and then explains how to construct a one-tailed confidence interval and determine the sample size needed to achieve a user-defined confidence interval. Finally, the paper discusses the relationships between the hypergeometric and other distributions. The appendices explain the mathematics for implementing the hypergeometric distribution and the computer code for implementing the distribution in VBA for Excel.

The Newsvendor Problem $5.00 Buy Now
A paper that explains the newsvendor problem in great depth. This paper describes a wide variety of problems that can be modeled with the newsvendor model, including finding the optimal quantity for buying seasonal products, for making a last buy, for setting the trunk stock level, for overbooking a flight, for setting a safety stock, etc. The paper develops both the discrete and continuous versions of the model and provides examples of both. This is a companion paper to the Newsvendor Model.xls Excel workbook.

The RACI Chart $5.00 Buy Now
This paper explains how to use the RACI Chart for responsibility charting for process management, project teams, and workgroups. RACI is an acronym for Responsible, Accountable, Consulted, and Informed. The RACI Chart can help remove ambiguity in roles, which results in less blaming, waste, and redundancy, and more capacity and productivity. This paper ends with a one-page summary that is suitable for use as a handout.

The Relationship between the MAD and the Standard Deviation $5.00 Buy Now
This paper provides derives the mathematical relationship between the Mean Absolute Deviation (MAD) and the standard deviation for any continuous distribution. The paper then develops this exact relationship for the normal distribution. In the context of a small example and a Monte Carlo simulation, the paper then argues that the MAD is more conservative for small samples than the standard deviation and a more robust when “special cause” outliers are in the data, which suggests that 1.25MAD is a reasonable substitution for the standard deviation in forecasting and inventory management applications.

The Runs Test $5.00 Buy Now
This paper presents the methodology for the runs test. This paper includes the details for how to implement the runs test for larger sample sizes when the normal approximation is appropriate and also for smaller sample sizes when the exact runs distribution should be used. A table for the exact probabilities is presented in the appendix.
