Greer decision is linked with the inconsistency of the quality of services.
<u>Explanation:
</u>
The consistency with which the service attributes anticipated for customers are delivered is a reliable measurement of total quality in the service industry. Consistency defines how sometimes you demonstrate and offer your clients the desired service quality.
Consistency of service is always expected by all customers; they want calm and no disagreeable surprises. In manufacturing, performance improvement is accomplished via a technique called statistical control of processes or SPC to minimize system uncertainty or variability.
For example, you can't create a consistent quality of service if you're prompt, correct and polite to certain of your customers, sometimes in all your branches. Therefore to say, good service turns into an error. Credibility will not be lasting or successful.
