Illustration: The black circle represents the system, with its Functions, and the black arrow represents the Quantification-Scale of one of many Product-Values. The two points on the Quantification-Scale, Tolerable-Limit and Goal-Level, marks the dividing line between where the Product-Value is Intolerable, to where it is Tolerable, and from where it is Tolerable to where it is Successful.
- If a Goal-Level is contracted for but not reached, partial payment can be agreed upon within the Tolerable-Range
- There can be more than one Tolerable-Range for each unique set of Qualifier-Conditions.
A series of “.” indicates a Intolerable-Range

History of Concept
In the Competitive-Engineering book Tom described many possible Ranges (Failure-Range, Catastrophe-Range, Success-Range, Acceptable-Range, Total/Absolute-Range) together with many Levels (Goal, Fail, Catastrophe, Disaster, Ideal, Streatch, Wish etc,). When teaching and in actual usage it became a little too much for most people. So we simplified it to Intolerable-Range, Tolerable-Range and Success-Range together with Tolerable-Limit and Goal-Level.
