What does Philip Crosby mean by the following?

Conformance to Specification Prevetion, not Inspection A process, not a programme, improvement goals Cost of nonconformance; quality is free Yes and buyers quality audits useless

 

Evaluate briefly the philosophical stance of Quality Gurus: Philip Crosby and
Joseph Juran on the following thematic areas:
i. General Approach to Quality
ii. Structure
iii. Performance Standards/Motivation
iv. Cost of Quality
v. Improvement basis

Most organizations in their bid to increase performance plan and implement activities to improve the total quality program to achieve their set targets. Briefly discuss with practical examples, 5 techniques or tools used to DEFINE (use DMAIC model) a process that requires improvement. 

If we do things right, there is nothing to fix. Discuss this statement in relation to the cost of quality where prevention, appraisal, internal failure and external failure constitute cost of quality. How does this align with the philosophical stance of Philip Crosby?
