Question: The probability of it snowing or not snowing in New York City would not fit the criteria for a Binomial Distribution even though there are only 2 outcomes - it will snow or it will not snow. Why can't you use the binomial distribution for this problem?

Snowing and not snowing is not a two-state condition.
It would be impossible to define a fixed number of trials.
It is impossible to use binomial distributions for weather issues.

Show or Reveal the Answer
JIT does not allow very much flexibility in the products produced
Comparing JIT to synchronous manufacturing, JIT does an excellent job in reducing lead times and work-in-process, but it has several drawbacks:
1. JIT is limited to repetitive manufacturing.
2. JIT requires a stable production level (usually about a month long).
3. JIT does not allow very much flexibility in the products produced.
4. JIT still requires work-in-process when used with kanban so that there is "something to pull."
5. Vendors need to be located nearby because the system depends on smaller, more frequent deliveries.

JIT uses a schedule to assign work to each workstation
Key Points: JIT still requires work-in-process when used with kanban. Synchronous manufacturing uses a schedule to assign work to each workstation. Thus, there is no need for more work in process other than that being worked on.

34.85%
Explanation: The probability that the order executed through this 5 sub-processes in series is defect free is 34.85%.
To calculate the percent yield of these 5 sub-processes is: YRT = yt1 X yt2 X yt3 X yt4 X yt1. Thus, the calculation is as follows: YRT = 0.80 X 0.82 X 0.80 X 0.80 X 0.83 = 0.3485 = 34.85%.

Explanation : 5S is the acronym for five Japanese words: Seiri (Sort), Seiton (store or Set in order/place), Seiso (Shine), Seiketsu (Standardize) and Shitsuke (Sustain) and they represent the five steps for a systematic technique for good housekeeping.
