Flow Line Pacing | All About Lean | Christoph Roser

“There are three different options on how to time the production lines.[…] The “easiest” one is an unstructured approach. The processes are still arranged in sequence; however, there is no fixed signal when to start processing a part. The pulse line is also a flow line, but now all parts move at the same time. […] When all processes are done, all parts move to the next process simultaneously. […] Another common way to structure the timing of flow lines is the continuously moving line.”

Michel Baudin‘s comments: Christoph’s two posts are great for their rifle-shot focus on the single issue of flow line pacing and for their effective use of animation to illustrate principles. It makes the differences clear in a way you couldn’t on paper.

New Chart Junk: Squaring The Pie
The purpose of graphics for data visualization is communication, not decoration, which is often forgotten in publications as well as on company performance dashboards. A case in point is the chart on yesterday’s cover of the New York Times. It shows that solar energy currently accounts for more than twice as many jobs as coal. It also shows the numbers of jobs in different sectors and uses a color code to mark some as based on fossil fuels versus renewable and low-emission technologies.
Until recently, most publications would have used a pie chart. Now, graphic artists have found a way to square the pie chart into yet another style that will most likely trickle down to slideware and office walls, in spite of a low data-to-ink ratio and the use of two-dimensional shapes to display one-dimensional data.
