We often encounter cartographic visualizations as a way to explain spatial comparisons. Although they are great eye-catchers, there are rather difficult to use (well). Learn when (and if!) it makes sense to use these chart types to visualize business data.

Smoke signals aren’t enough – using the gross margin flow analysis, Part II

Last week, a sales region was charged with underestimating sales elasticity and letting a price increase lead to a drop in sales volume. The verdict this week? The sales region is found ‘not guilty’ – thanks to the undisputable evidence of gross margin flow analysis and a simple ranking.

Art and Data Analysis I

Data analysis is a true art form. To present your results effectively, you need craftsmanship, creativity and drive. Appropriately, I find that exhibitions and books about art are a source of inspiration for anyone who deals with data analysis.

Looking for an iPod for data analysis?

Simplicity is en vogue. A pleasurable representative is the iPod from Apple. It provides guidance for many other concepts and products and also inspires data analysts. If you ask me, rankings are the next best thing to an iPod for data analysis.

“Half of all companies don’t calculate their numbers correctly!“

The world’s first seminar on gross margin flow analysis was held on October 17, 2006 in Nuremberg, Germany. Managers from Audi, Nordsee, Sanitop and wolfcraft shared their experiences with this innovative method of deviation analysis. The father of gross margin flow, Professor Dr. Jörg Link, held the key note speech. Some more in-depth insight into his theory and its practical reference are available in my interview with him.

Numerical blindness?

When diagnosed with AIDS or breast cancer, most people feel as if they have been sentenced to death. Is this justified? Provided that he or she doesn’t belong to a high-risk group, a person only really carries the HIV virus 50 % of the time and actually has breast cancer in 10 % of the cases. The problem, however, is that most doctors tell a different story. That has to do with how information is presented. Gerd Gigerenzer offers insight to understand and interpret vital information correctly.
