Moving Beyond Product Quality

Posted on June 12, 2012 by John Hunter

This month Paul Borawski (CEO of ASQ) has asked the ASQ Influential Voices to share their thoughts on moving beyond product quality. The opening paragraph of the Quality Council’s perspective is, “For some organizations, ‘quality’ remains a set of tools and techniques associated almost exclusively with quality control. For others, quality has evolved into a critical partner, closely linked with business model development and the enterprise-wide execution of long-term strategy to achieve results. The way to move beyond just the … Continue reading →

Richard Feynman Explains the PDSA Cycle

Posted on May 17, 2012 by John Hunter

Ok, really Richard Feynman Explains the scientific method. But his thoughts make the similarity between the PDSA cycle and the scientific method obvious. 1) Plan, hypothesis. You make a guess about a theory (in using the PDSA cycle this step is often missed, while in the scientific method this is of the highest priority). You make a prediction based on that theory. 2) Do the experiment 3) Study the results If the results disprove the theory you were wrong. If … Continue reading →

I have selected a few great posts from the Curious Cat Management Blog back in November 2006. What Could we do Better? – There are many important ideas to improve management. This is one of the most important tips to aid improvement that I know of: it is easy to do, brings huge benefits and most organizations fail to do it.

Keys to the Effective Use of the PDSA Improvement Cycle

Posted on March 6, 2012 by John Hunter

The PDSA improvement cycle was created by Walter Shewhart where Dr. Deming learned about it. An improvement process is now part of many management improvement methods (A3 for lean manufacturing, DMAIC for six sigma and many other modifications). They are fairly similar in many ways. The PDSA cycle (Plan, Do, Study, Act) has a few key pieces that are either absent in most others processes of greatly de-emphasized which is why I prefer it (A3 is my second favorite). The … Continue reading →

Why Use Lean if So Many Fail To Do So Effectively

Posted on February 15, 2012 by John Hunter

If less than 1% of companies are successful with Lean, why are we doing it? Lots of us are not. I would say the efforts I see “fail” are because they don’t do it. They have something they call TQM, six sigma, lean management or whatever and try out 10-30% of it in some half-measures, with big doses of Dilbert’s pointy haired boss methods and then don’t get great results. Wow. The biggest complaint (with some merit) I see is … Continue reading →

Agile Story Point Estimation

Posted on February 8, 2012 by John Hunter

In agile software development tasks are documented as user stories. Then the level of effort for those stores can be estimated by assigning each story points. The velocity that can be produced in a period (called a sprint, for us 2 weeks) can be estimated. Thus you can predict what can be delivered in the next sprint (which can help business managers make priority decisions). I have found estimation to be worthwhile. In doing so, we accept there is a … Continue reading →

Trust But Verify

Posted on January 16, 2012 by John Hunter

The following are my comments, which were sparked by question “Trust, but verify. Is this a good example of Profound Knowledge in action?” on the Linked In Deming Institute group. Trust but verify makes sense to me. I think of verify as process measures to verify the process is producing as it should. By verifying you know when the process is failing and when to look for special causes (when using control chart thinking with an understanding of variation). There … Continue reading →

Eliminate the Waste of Waiting in Line with Queuing Theory

Posted on December 15, 2011 by John Hunter

One thing that frustrates me is how managers fail to adopt proven strategies for decades. One very obvious example is using queuing theory to setup lines. Yes it may be even better to adopt strategies to eliminate as much waiting in line as possible, but if there is still waiting in line occurring and you are not having one queue served by multiple representatives shame on you and your company.

Dr. Deming in 1980 on Product Quality in Japan and the USA

Posted on December 5, 2011 by John Hunter

I posted an interesting document to the Curious Cat Management Library: it includes Dr. Deming’s comments as part of a discussion organized by the Government Accounting Office in 1980 on Quality in Japan and the United States. The document provides some interesting thoughts from Dr. Deming and others; Dr. Deming’s statements start on page 52 of the document. For those really interested in management improvement ideas it is a great read. I imagine most managers wouldn’t enjoy it though (it … Continue reading →

I have selected a few posts from the Curious Cat Management Blog back in October 2006 for those of you who were not reading this blog then. Why Pay Taxes or be Honest – “I don’t think acting illegally, immorally, unethically is excusable just because lots of other people are… It is sad how bad the behavior is that is considered acceptable.” Hiring the Right Workers – “The job market is an inefficient market. There are many reasons for this … Continue reading →

Not Ambiguous Sign

Posted on August 18, 2011 by John Hunter

I like the series of posts by Jon Miller on Ambiguous signs (another example). Here is a sign that got my attention recently and they succeeded in keeping me away (which I think was their intention). The area is near the Royal Palace in Johor Bahru Malaysia, though I am not certain that is what the restricted area is. It isn’t obvious to me why this location requires shooting trespassers, but I took the idea from the sign to stay … Continue reading →

Visual Management with Brown M&Ms

Posted on August 15, 2011 by John Hunter

When you hear about rock musicians having a clause in their contract that they must have a bowl of M&Ms in their dressing room with all the brown M&Ms removed you could be excused for thinking: what will these crazy celebrities do next. Well it might just be those crazy celebrities are using visual management (granted I think there could be better methods [a bit more mistake proofing where the real problems would be manifest] but it is an interesting … Continue reading →

Good Execution Can Make Management Tools Like Time and Motion Studies Useful

Posted on August 11, 2011 by John Hunter

In my experience most management concepts are applied poorly. Many of the concepts may also be bad. For example, performance appraisals are both done poorly and a bad idea. The solution is not to do performance appraisal righter: for what to do read Peter Scholtes. But, many tools and concepts that are applied with poor results, where the actual application is criticized (with good reason), can be used successfully. I would put benchmarking and time and motion studies in that … Continue reading →

One factor at a time (OFAT) Versus Factorial Designs

Posted on May 25, 2011 by John Hunter

Guest post by Bradley Jones Almost a hundred years ago R. A. Fisher‘s boss published an article espousing OFAT (one factor at a time). Fisher responded with an article of his own laying out his justification for factorial design. I admire the courage it took to contradict his boss in print! Fisher’s argument was mainly about efficiency – that you could learn as much about many factors as you learned about one in the same number of trials. Saving money … Continue reading →

Factorial Designed Experiment Aim

Posted on April 25, 2011 by John Hunter

Multivariate experiments are a very powerful management tool to learn and improve performance. Experiments in general, and designed factorial experiments in particular, are dramatically underused by managers. A question on LinkedIn asks? When doing a DOE we select factors with levels to induce purposely changes in the response variable. Do we want the response variable to move within the specs of the customers? Or it doesn’t matter since we are learning about the process? The aim needs to consider what … Continue reading →

Assigning Story Points to Bug Fixes

Posted on January 27, 2011 by John Hunter

Agile software development has teams estimate the effort to deliver requests from the product owner. The estimates are done in points (in order to abstract away from hours – as estimates have plenty of variation in how long they will really take). Then the teams capacity (velocity) is determined based on looking at how many points they complete in a “sprint” (a set length, often 2 weeks). Then the product owner can prioritize all of the requests with an understanding … Continue reading →
