The profile of a product can be recorded as a star diagram. Testers rate characteristics on a five point scale (1 being the lowest and 5 being the highest)
76 of 143
Why do we modify products?
Any changes to the design specification need to be made before the final manufacturing specification is prepared. For example, sensory testing may reveal that the food is too spicy, so the ingredients may need to be modified.
77 of 143
