5S $5.00 Buy Now
This paper explains how a 5S program can improve a work environment to improve visibility, which in turn improves productivity, safety, cycle time, and quality. The paper provides a detailed description of each of five steps, the benefits of a 5S program, and how to implement a 5S program. The paper also provides an example for a crash cart in a clinic. The appendix presents a scorecard for a 5S audit.

An Overview of Mapping Tools for Process Improvement $5.00 Buy Now
This paper overviews and compares a wide variety of mapping tools that can be used to understand and improve a process. The mapping tools included in this paper include relational mapping tools (mindmaps, work breakdown structures, and organizational charts), time mapping tools (process maps, value stream maps, and project networks), and causal mapping tools. These include causal maps, Ishikawa (Fishbone, Cause & Effect) diagrams, strategy maps, impact wheels, root cause trees, issue trees, and goal trees. Closely related papers include “Mind Mapping,” “Causal Mapping,” “Strategy Mapping,” “Process Mapping,” and “Value Stream Mapping.” These papers provide more detail on each of these mapping tools.

An Overview of the Minto Pyramid Principle $5.00 Buy Now
This paper overviews the Minto Pyramid Principle, which is a structured approach to building a persuasive argument and presentation developed by Barbara Minto, a former McKinsey consultant (Minto 1987). The Minto Pyramid Principle has become the de facto standard for all major consulting firms worldwide. Minto’s approach can improve almost any presentation and almost any form of persuasive speech.

Audit Sampling $5.00 Buy Now
A paper that presents a hypergeometric probability distribution approach for audit sampling. The paper presents the methodology for setting up a stop and go sampling plan for an audit based on the hypergeometric distribution. This distribution is the most precise approach for auditing and results in the lowest recommended sample size. The companion Excel workbook “Audit Sampling.xls” implements the sampling model developed in this paper.

Balanced Scorecards and Strategy Maps $5.00 Buy Now
This paper argues for the use of (1) balanced scorecards to align organizations with the strategic objectives and (2) strategy maps to develop the “hypotheses” for how tactical actions will affect strategic outcomes. The paper presents practical approaches for creating both balanced scorecards and strategy maps. The paper presents many suggestions for improving both the standard Kaplan and Norton balanced scorecards and strategy maps. A number of examples are presented, including a time-based competition example.

Causal Mapping $5.00 Buy Now
This paper provides detailed information on how to create and use a causal map. The paper compares a traditional Ishikawa (Fishbone, Cause & Effect) diagram with the more general causal map and argues that the more general causal map is easier to use and more flexible. The paper presents a number of best practices for causal mapping that go far beyond the teaching normally provided with the Fishbone Diagram.

Correlation Significance Test $5.00 Buy Now
This paper explains how to conduct a statistical test to determine if the correlation between two continuous variables and the sample size are large enough to conclude that the correlation is statistically significant. This is a companion to the Excel workbook by the same name.

Dollar Unit Sampling $5.00 Buy Now
A paper that presents a complete methodology for Dollar Unit Sampling (DUS). DUS is a powerful and useful method for sampling when you have a population with some importance measure such as the recorded amount available. Compared to random sampling, DUS provides greater representation of the larger recorded amounts in the sample and creates a more precise (tighter) confidence interval for the same sample size. It is also easier to use than other types of sampling methodologies such as stratified random sampling. DUS has become the standard approach for statistical auditing. This is a companion paper for the Excel workbook “dus.xls.”

Empirical Probability Distributions with Theoretical Tails $5.00 Buy Now
This paper presents approaches for generating values from both continuous and discrete empirical probability distributions. This paper contends that adding a theoretical “tail” to an empirical distribution allows simulations to experience values beyond the historical tail values – and allows these simulations to explore important real-world “catastrophic” issues more carefully.
