According to a U.S. Department of Health and Human Services’ webpage on Radiation Emergency Medical Management:
- “Radioactive half-life is the time required for a quantity of a radioisotope to decay by half.
- If the half-life of an isotope is relatively short, e.g. a few hours, most of the radioactivity will be gone in a few days.
- If the half-life of an isotope is relatively long, e.g. 80 years, it will take a long time for significant decay to occur.”
So, enough about isotopes. What about lean “culturetopes?”
If “lean” was discontinued within your organization, how long would it take for people to revert to their native batch-and-queue behaviors? How long would it take for most of the “leanness” to be gone?
Perhaps. But, I think the question can prompt some useful reflection.
What would happen if the number one executive lean leader within your company left for greener pastures? Would the lean transformation stop dead in its tracks? Or would the organization shake it off and, due to the profound depth of the lean cultural evolution, continue rolling?
What would happen if there was a sudden, substantial drop in business? What if the company introduced some wizbang new technology? What if your company was acquired? What if...?Is your lean half-life measurable in minutes, hours, days, weeks, months, or years?
I think that the Shingo Prize Behavior Assessment Scale (see figure) can provide meaningful insight into an organization’s lean cultural half-life. The further to the right on the Assessment Scale, the longer the lean half-life…by a lot!
What are your thoughts?
