| Entrance | What is it used for? |
| Specigraph | Determine the tolerance for one or two X characteristics based on the specification for Y, using a scatter plot of measured data and regression analysis. It also works the other way around: fix the tolerances for X and see what happens to Y. |
| Monte Carlo Simulation | Given an equation Y = f(X₁…Xₙ) and the tolerances for the X variables, determine the distribution of Y, the nonconformance rate, the risk per batch, and the sensitivity of each factor. |
| Dimension Lines | Distribute the tolerances across several dimensional chains that are linked to one another. |
💡 The first two entries share the same screen layout: data entry on the left, an “Intention” column where you specify what you’re looking for, charts in the center, results on the right, and a full-width summary banner at the bottom. This banner is the menu’s signature feature: it shows who benefits from Y’s tolerance and what actually remains to be distributed.
