Fundamentals of Performance Metrics | Bill Waddell
See on Scoop.it – lean manufacturing
Received a question the other day: “If you were allowed to use 3 metrics to operate by, what would they be (and why) if you were: (1) a CEO, (2) a Plant Manager, (3) a Value Stream Manager, (4) a Purchasing Manager, and (5) a Sales Manager.” In…
A thoughtful, rant-free article, focused primarily on the language of money. My few blog posts on the subject were on metrics in the language of things, as spoken on production shop floors:
- Chart junk in performance boards and presentations
- Companies focus on what is easy to measure
- Metrics in Lean recorded webinar
- Alternatives to Rank-and-Yank in Evaluating People
- Productivity of a Quality Assurance department
- Lead times and inventory
- Metrics on the web versus manufacturing
- Metrics gaming and how to prevent it
- Metrics of Equipment
- Metrics of Quality
- Requirements on Metrics
- The staying power of bad metrics
- Orbit charts, and why you should use them

Stop ropes and Andons at Ford’s River Rouge Plant in 1931
Mark Warren pointed out to me the description of a stop rope with and Andon board in a book called Ford Men and Methods, by Edwin P. Norwood, with illustrations by Charles Sheeler, including his famous crossing conveyors.
First, on p. 1:
Following is a picture of an Andon board from Toyota Georgetown today:
Unlike the example described above, it is not located in a control room but on the shop floor for production supervisors to see, and green lights are not used for alarms anymore. Perhaps, in 1931, the green-yellow-red color code had not yet become a cultural constraint.
Then on p. 10:
The description of the stop rope matches exactly this picture from Toyota Georgetown, and it still resembles the cord on a city bus that you pull to tell the driver to let you off at the next stop.
