Use the helo exercises when training team members because you can exhibit almost any concept in 6sigma *and* lean. We use dots and manufacture batches of helos to teach the concepts of takt time/batch size/standard work. You can then use the manufactured helos to teach statistical concepts. Once they’ve improved the flow of their factory, you…[Read more]

Time-triggered sampling plans usually don’t get far when you have single-use devices. The only long-term so…[Read more]
Good points made here. Agree that 30% is a good swag and it takes 5-10 years to see noticable change.
In electronic materials, if you combine particles that are resistive (sand) and conductive (steel BB’s), whether the resulting mixture of materials conducts depends on the % conductor. It so happens that at about 30%, the mixture begins to c…[Read more]
Here’s a few sources that elucidate the failure modes quite well:
