Annual Performance Reviews Are Obsolete

Posted on November 15, 2010 by John Hunter

Sam Goodner, the CEO of Catapult Systems, wrote about his decision to eliminate the annual performance appraisal [the broken link was removed]. the most critical flaw of our old process was that the feedback itself was too infrequent and too far removed from the actual behavior to have any measurable impact on employee performance. … I decided to completely eliminate of our annual performance review process and replace it with a real-time performance feedback dashboard.” I think this is a … Continue reading →

Managing Our Way to Economic Success

Posted on August 23, 2010 by John Hunter

From Managing Our Way to Economic Success, Two Untapped Resources by William G. Hunter, my father. Written in 1986, but still plenty relevant. We have made some good progress, but there is much more to do: we have barely started adopting these ideas systemically. there are two enormously valuable untapped resources in many companies: potential information and employee creativity. The two are connected. One of the best ways to generate potential information to turn it into kinetic information that can … Continue reading →

How to Manage What You Can’t Measure

Posted on August 4, 2010 by John Hunter

In Out of the Crisis, page 121, Dr. Deming wrote: the most important figures that one needs for management are unknown or unknowable (Lloyd S. Nelson, director of statistical methods for the Nashua corporation), but successful management must nevertheless take account of them. So what do you do then? I am a strong advocate of Deming’s ideas on management. I see understanding system thinking, psychology, the theory of knowledge and variation as the tools to use when you can’t get … Continue reading →

Actionable Metrics

Posted on July 22, 2010 by John Hunter

Metrics are valuable when they are actionable. Think about what will be done if certain results are shown by the data. If you can’t think of actions you would take, it may be that metric is not worth tracking. Metrics should be operationally defined so that the data is collected properly. Without operationally definitions data collected by more than one person will often include measurement error (in this case, the resulting data showing the results of different people measuring different … Continue reading →

Problems With Student Evaluations as Measures of Teacher Performance

Posted on June 16, 2010 by John Hunter

Dr. Deming was, among other things a professor. He found the evaluation of professors by students an unimportant (and often counterproductive measure) – used in some places for awards and performance appraisal. He said for such a measure to be useful it should survey students 20 years later to see which professors made a difference to the students. Here is an interesting paper that explored some of these ideas. Does Professor Quality Matter? Evidence from Random Assignment of Students to … Continue reading →

Taxes per Person by Country

Posted on April 7, 2010 by John Hunter

I think that the idea that data lies is false, and that such a notion is commonly held a sign of lazy intellect. You can present data in different ways to focus on different aspects of a system. And you can make faulty assumptions based on data you look at. It is true someone can just provide false data, that is an issue you have to consider when drawing conclusions from data. But often people just don’t think about what … Continue reading →

Making Better Decisions

Posted on November 24, 2009 by John Hunter

I think the most important thing you can do to make better decisions is to learn from the decisions you make. It sounds easy, but very few people do so effectively. The best strategy to learn from decisions is to: predict the results of your decisions write down those predictions Then analyze the results Then adjust future predictions and decisions based on what you learn Failing to do this leads most people to fail to learn from there decisions. It … Continue reading →

Highlights from Recent George Box Speech

Posted on November 16, 2009 by John Hunter

The JMP blog has posted some highlights from George Box’s presentation at Discovery 2009 [the broken link was removed] Infusing his entire presentation with humor and fascinating tales of his memories, Box focused on sequential design of experiments. He attributed much of what he knows about DOE [design of experiments] to Ronald A. Fisher. Box explained that Fisher couldn’t find the things he was looking for in his data, “and he was right. Even if he had had the fastest … Continue reading →

Deming: There is No True Value

Posted on November 5, 2009 by John Hunter

There is no true value of anything: data has meaning based on the operational definition used to calculate the data. Walter Shewhart’s Statistical Method from the Viewpoint of Quality Control, forward by W. Edwards Deming: There is no true value of anything. There is instead a figure that is produced by application of a master or ideal method of counting or measurement… no true value of the number of inhabitants within the boundaries of (e.g.) Detroit. A count of the … Continue reading →

Communicating with the Visual Display of Data

Anscombe’s quartet: all four sets are identical when examined statistically, but vary considerably when graphed. Image via Wikipedia. ___________________ Anscombe’s quartet comprises four datasets that have identical simple statistical properties, yet are revealed to be very different when inspected graphically. Each dataset consists of eleven (x,y) points. They were constructed in 1973 by the statistician F.J. Anscombe to demonstrate the importance of graphing data before analyzing it, and of the effect of outliers on the statistical properties of a dataset. … Continue reading →

Managing to Test Result Instead of Customer Value

Posted on October 19, 2009 by John Hunter

Computer hardware and software creators use benchmarks as one tool to compare the performance of alternative products. At times this can be very useful. You can learn what software of hardware is faster and that may be a very valuable factor. However, any measure is determined by the operational definitions used in collecting the measure. And if people have incentives to improve the measured number they often will do just that (improving the measure) rather than improving the system (the … Continue reading →

Posted on August 17, 2009 by John Hunter

Google does a great job of using statistical and engineering principles to improve. It is amazing how slow we are to adopt new ideas but because we are it provides big advantages to companies like Google that use concepts like design of experiments, experimenting quickly and often… while others don’t. Look Inside a 1,024 Recipe Multivariate Experiment A few weeks ago, we ran one of the largest multivariate experiments ever: a 1,024 recipe experiment on 100% of our US-English homepage. … Continue reading →

Making things visible is a key to effective management. And data in computers can be easy to ignore. Don’t forget to make data visible. Paul Levy, CEO of Beth Israel Deaconess Medical Center in Boston recently hosted Hideshi Yokoi, president of the Toyota Production System Support Center and wrote this blog post: Together, we visited gemba and observed several hospital processes in action, looking for ways to reduce waste and reorganize work. It was fascinating to have such experts here … Continue reading →
