The Different Views of Quality by Quality Gurus

Industry accepted definitions of quality are

a. “Conformance to Requirements” stated by Philip Crosby
b. “Fit for Use” stated by Dr. Joseph Juran and Dr. W. Edwards Deming

These two definitions are not inconsistent.

The Two Quality Gaps

Most Information Technology (IT) groups have two quality gaps: the Producer gap and the Customer gap.

The producer gap is the difference between what is specified (the documented requirements and internal standards) versus what is delivered (what is actually built).
The customer gap is the difference between what the producers actually delivered versus what the customer wanted.
