This document provides an introduction to quality standards and definitions. It discusses that there are different views of quality, including degree of fulfillment of requirements, fitness for use, and meeting customer expectations. It also summarizes that quality is not achieved by accident but requires understanding customer requirements and having a plan to meet them. Quality involves a continuous improvement cycle of plan, do, check, act. Finally, it notes that quality management systems, like ISO 9001, provide requirements for organizations to direct quality in a systematic way.

Customer Feedback and Word-of-Mouth
• The average business only hears from 4% of its customers who are dissatisfied with
its products or services. Of the 96% who do not bother to complain, 25% of them
have serious problems.
• The 4% complainers are more likely to stay with the supplier than are the 96% non-
complainers.
• About 60% of the complainers would stay as customers if their problem was
resolved and 95% would stay if the problem was resolved quickly.
• A dissatisfied customer will tell between 10 and 20 other people about their
problem.
• A customer who has had a problem resolved by a company will tell about 5 people
about the situation.

An Approach to Viewing Quality.
Slack et al 2004
• The transcendent approach views quality as synonymous with innate excellence
e.g. Rolls Royce, Rolex, The Hilton.
• The manufacturing-based approach assumes quality is all about making or providing error-free
products or services e.g. Audi’s ‘vorsprung durch technik’.
• The user-based approach assumes quality is all about providing products or services that are fit
for their purpose e.g. it does what it says on the tin!
• The product-based approach views quality as a precise and measurable set of characteristics
e.g. 0-60 in 4.3 seconds.
• The value-based approach defines quality in terms of value’ e.g. supermarket ‘value’ ranges.
