Even if every individual part is "within spec," their combined variation can cause interference (parts too big for their space) or excessive gaps (parts too loose). Predict Failure:

The Board refused. "If the part is out of spec, it's a failure," they argued. They couldn't see the forest for the microns. Even if every individual part is "within spec,"
What exactly makes a calculator “exclusive”? Below is a feature set that separates professional-grade software from amateur widgets. The Board refused
A stack up analysis identifies "Red Flag" zones where an assembly is statistically likely to fail. By running simulations (such as Monte Carlo analysis within advanced calculators), engineers can predict defect rates (e.g., "3 parts per million will fail to fit") before a single chip is cut.
from Minitab, simulate thousands of assembly combinations to provide a probability of failure and capability metrics like Ppk/Cpk.
