Measurement Discrimination

Measurement discrimination is used in Six Sigma when analyzing variation in a process. It can also be a useful concept in the bakery for scaling ingredients and measuring temperature.


With higher measurement discrimination, the Unit of Measure increments are smaller, and vice versa. For example, grams have a high weight discrimination, and kilograms have a low weight discrimination. If you put an extra gram or two into your final dough, it may not make any difference. However, if you put an extra kilogram or two in, the dough will likely be affected and stiffer than desired.


Using measurement systems with high measurement discrimination helps us achieve less deviation from target weights and temperature. This is the primary reason I use grams (metric system) to measure weight and Fahrenheit (imperial system) to measure temperature.
