Data Visualization

Data is often displayed poorly, making it difficult to see what is important. When data is displayed well the important facts should leap off the page and into the viewers mind. Edward Tufte is an expert on this topic with great books. If you have not read them, you should: Beautiful Evidence, The Visual Display of Quantitative Information, Envisioning Information and Visual Explanations. Smashing magazine has some nice examples of good display techniques in Data Visualization: Modern Approaches. I don’t … Continue reading →

Data Can’t Lie

Many people state that data can lie. Obviously data can’t lie. There are three kinds of lies: Lies, damn lies and statistics – Mark Twain Many people don’t understand the difference between being manipulated because they can’t understand what the data really says and data itself “lying” (which, of course, doesn’t even make sense). The same confusion can come in when someone just draws the wrong conclusion from the data that exists (and them blames the data for “lying” instead … Continue reading →

Be Careful What You Measure

Be Careful What You Measure by Mike Wroblewski: Although this recalculation of productivity had a positive affect, it is not what I would consider a triumph. Ongoing efforts are still required to truly increase productivity, so it’s back to gemba. However, I am modifying the lesson to “Be careful what and how you measure, measurements drive action and behavior” Excellent points. Behavior can be changed by what is measured. The problem with arbitrary numerical targets (to take one measurement related … Continue reading →

Data Visualization Example

[I replaced the embedded video, since Google broke the original link with the way they shut down Google Video after buying YouTube] In Myths About the Developing World, Hans Rosling shows some great graphics to display data on health care outcomes. This is one of the talks from the great TED conference that we have mentioned before. They really have some great webcasts available on their site. The presentation also gives a concrete example of faulty knowledge (people thinking things … Continue reading →

Metrics and Software Development

Lean-based Metrics for Agile CM Environments [the broken link was removed] by Brad Appleton, Robert Cowham and Steve Berczuk: Measure Up! Don’t use metrics to measure individuals in a way that compares their performance to others or isolates the value of their contributions from the rest of the team. The last of the seven principles of Lean software development tells us to “Optimize across the whole.” When measuring value or performance, it is often better to measure at the next … Continue reading →

Game Theory Management

Interesting article on applying game theory to business decisions. Game theory is a tool that is not often used. Though most organizations are probably better off improving how they use the rest of their management tools, it is fun to read about and does have merit in the right situations. 16,777,236 [the broken link was removed] – That’s the number of outcomes that are possible when eight competitors each consider three strategic options. California Institute of Technology professor R. Preston … Continue reading →

Customer Un-focus

Counties caught in conundrum: getting Amish to take food stamps [the broken link was removed] by John Horton Accepting public assistance is verboten within the Amish culture. It simply is not done. But Taylor is under orders to at least try to get them enrolled. The Ohio Department of Job & Family Services has asked Geauga and Holmes counties, which feature the state’s largest Amish populations, to lift dismal food-stamp participation rates. Taylor and his Holmes counterpart, Dan Jackson, called … Continue reading →

Common Cause Variation

Every system has variation. Common cause variation is the variation due to the current system. Dr. Deming increased his estimate of variation due to the system (common cause variation) to 97% (earlier in his life he cited figures around 80%). Special cause variation is that due to some special (not part of the system) cause. The control chart (in addition to other things) helps managers to avoid tampering (taking action on common cause variation as though it were a special … Continue reading →

Deming in the New Economy

I just read an interesting paper (found via – Stating the Obvious [the broken link was removed]): New Economy Concepts and the Application of Deming’s Theories on Management [the broken link was removed] by Christian Buckley and Arthur Close All measures should supply accurate information usable for making good decisions. To paraphrase Dr. Deming – if you don’t know how to use the answer to improve you process, the calculation(s) were a waste of time. Great point, see: Measurement and … Continue reading →

Gladwell (and Drucker) on Pensions

The Risk Poolhttps://management.curiouscatblog.net/2006/08/21/gladwell-and-drucker-on-pensions/ by Malcolm Gladwell (author of The Tipping Point and Blink): The most influential management theorist of the twentieth century was Peter Drucker, who, in 1950, wrote an extraordinarily prescient article for Harper’s entitled “The Mirage of Pensions.” It ought to be reprinted for every steelworker, airline mechanic, and autoworker who is worried about his retirement. Drucker simply couldn’t see how the pension plans on the table at companies like G.M. could ever work. “For such a plan … Continue reading →

Distort the System

From our post: Targets Distorting the System, Dr. Brian Joiner: spoke of 3 ways to improve the figures: distort the data, distort the system and improve the system. Improving the system is the most difficult. Another example of this in practice: Recount helps one university rise in the rankings [the broken link was removed]: Behnke, who says he’s no fan of rankings, said he recently spoke to a provost at another institution who was capping class sizes at 19 to … Continue reading →

Usability Failures

‘Smart’ phones, stupid punters? A survey* of 15,000 “faulty” devices by mobile data provider WDSGlobal found 63 per cent of the one in seven new phones which are returned have nothing wrong with them. I believe one in seven is the model of phone. I guess if you operationally define “nothing wrong” as a failure to work as the manufacturer intended that would be true. But is that what really matters? What is the number of defects that should be … Continue reading →

The Customer Knows Best?

The Customer Knows Best? Better Think Again by Anthony W. Ulwick It’s important to listen to customers – but not follow their words without skepticism. Ask them to design your next product and you’re likely to miss the mark, suggests this Harvard Business Review excerpt. Excellent point. Some management ideas are pretty easy and straight forward. But many management practices require knowledge and judgment to apply them successfully. Easy solutions may be desired, but, often you must choose between easy … Continue reading →

Understanding Data

Statistics Abuse and Me [the broken link was removed] by Jay Mathews: the Simpson’s Paradox numbers.

How can that be? Is it important? First, yes it is important. Effective use of data is … Continue reading →

Using Design of Experiments

How to Institute DOE in Your Company (link broken – removed) by Davis Balestracci: DOE works, but I don’t need to sell that to the readers of this newsletter. But as certain as we all are, no one can deny that design of experiments faces resistance even in environments where it is a proven tool. Every research scientist or engineer who has had a major success from DOE can tell you story after story of how management still wanted problems … Continue reading →
