One things that I note regarding the measurement phase. What would you advise about confirming measurement? A GR&R or a some sort of test such as t-test? On thing about the Takt time would be better to round down the take time to protect the customer?

Thank you. Yes, it helps. I knew it was probably something easy like that.

Thanks for the great question Charles. In hindsight, I probably could have been more clear with this section. Here is the explanation.

The total cycle time to make a sandwich is 97 seconds. However, when we work in one piece flow (no waiting or delay between steps) while using 3 operators we simply divide 97 by 3 which gets us around 32 seconds.

Now, this assumes we can balance the work evenly… essentially giving each operator around 32ish seconds of work to do.

In real life, it may be that operator 1 has 30 seconds of work, operator 2 has 35, and operator 3 has 32 seconds of work.

Does this help?

Can you clarify what you mean when you say, “Once the work was redistributed the team was able to produce a PB&J sandwich approximately every 32 seconds. The total time for the first sandwich to be complete is still 97 seconds.”

I am not sure I follow this? Is the cycle time 32 seconds or 97 seconds? And do the number of operators matter here?

Sorry if this is obvious. I am new to this and am trying to learn. Thank you.
