Weibull Distribution Example: A Transformation with Surprising Result

Business Intelligence and Analytics, Data Analysis /

Transformation of process data to achieve normality seems like magic, but it is not. There are a lot of reasons that specific transformations make sense and should be used, such as a lognormal transformation of standard deviations and of time data. But, when it comes to the Weibull distribution, there is no logical or inferential information that provides any guidance on a transformation to normality, until now. Rick Haynes has found a relationship between the Weibull distribution parameters and the optimal Box-Cox transformation lambda value. Through the use of the @Risk simulation program and Minitab, this article walks through the generation of an equation to predict a lambda value.

Enhanced Lean Process Management System in an Overall Business Management Framework

Business Management System, Integrated Enterprise Excellence /

Lean has a very good tool set; however, it is not a business management system. Practitioners may work with process improvement tools in organizational silos that often have little, if any, positive impact on the big picture. The Integrated Enterprise Excellence system addresses this need for overall orchestration of business operations with process improvement efforts. This article discusses how lean tools are integrated within the IEE system.

Problems with the Balanced Scorecard Resolved Through the IEE System

Enhanced Balanced Scorecard Reporting, Performance Measurements /

Have you have ever wanted to adopt the balanced scorecard philosophy into your organization? You may like the concept but find that it is not quite enough and has its limitations. The problems with the balanced scorecard methods are not in the generic sense of balance (which is good) but in the way the original authors choose to introduce balance into the scorecard ideas. This article walks through a vehicle to develop, implement, and apply the balanced scorecard to its fullest extent so that it will be useful to leadership.

Design of Experiments: Out of the Classroom

Uncategorized /

Teaching Design of Experiments to students is not an easy task. It is difficult to simulate the entire effort within the constraints of a classroom. You can teach the analysis with software, but this is not enough to really gain an understanding of DOE. In an effort to teach these concepts to a non-manufacturing audience, the DOE concepts were used to improve the baking of a chocolate chip cookie. You may say that is a manufacturing process and it is, but it involves all of the DOE concepts in an arena that most can understand. In this webinar we will walk through the entire process of planning, designing, running, and analyzing a factorial DOE. If you consider DOE a difficult concept and have a fear running one, this webinar is for you. By the end of the webinar, you will understand all the fractional factorial DOE concepts as well as know a few things about making chocolate chip cookies. We will even share the results of the DOE with you! Objectives: Walk through the key activities of a Design of Experiments (planning, designing, running, and analyzing ) in an area that you understand. At the end of the webinar you should feel much more comfortable in using a DOE, even outside of manufacturing.

Enhanced Management Control System

Business Management System, Integrated Enterprise Excellence /

People need to maintain control of their behaviors otherwise they might harm someone or their self. For example, people need to refrain from hitting someone when they get very upset with them. Similarly, companies need to have a control mechanism so that healthy policies and procedures are followed. If organizations don’t do this, problems can occur. We have seen the negative impacts on a global scale when companies do not have enterprise-wide control mechanisms that lead and drive healthy behaviors. This article discusses how to avoid some of this similar failures and how to create an effective business control system.
