Why is it difficult to define quality?
Expert Solution & Answer
To determine
Explain the reason for difficult to define quality.
Explanation of Solution
Justification:
The quality is the measure to which a product or service meets or exceeds the necessity of the customer. The two characteristics of a product or service that define quality are design quality and process quality.
Design quality would represent the specific characteristics, which is related to the design that are different for different customers.
Process quality would represent the reliability. The firm need to follow the standards and the specification in order to ensure the quality products for the customers.
It is difficult to define quality due to the reasons given below:
- Quality depends on the view of the persons or the products which they are using
- Various stages involved in defining the qualities, which makes challenging to define it.
- Quality can be changed over time, business, and per company as it is verified through the life dependability of the objects, serviceability, consistency, stability of the products, and so on.

Researchers measured thefollowing five aspects of the subjects’ direction-giving behavior:• whether a map was available or if directions were given from memory without a map,• the gender of the direction-giver,• the distances given as part of the directions,• the number of times directions such as “north” or “left” were used,• the frequency of errors in directions.

At a shooting range, instructors can determine if a shooter is consistently missing the target because of the gun sight or because of the shooter's ability. If a gun's sight is off, the variance of the distances between the shots and the center of the shot pattern will be small (even if the shots are not in the center of the target). A student claims that it is the sight that is off, not his aim, and wants the instructor to confirm his claim. If a skilled shooter fires a gun at a target multiple times, the distances between the shots and the center of the shot pattern, measured in centimeters (cm), will have a variance of less than 0.33. After the student shoots 28 shots at the target, the instructor calculates that the distances between his shots and the center of the shot pattern, measured in cm, have a variance of 0.25.
