Different perspectives of
Quality

20. BITS Pilani, Deemed to be University under Section 3 of UGC Act, 1956
David Garwin [1] proposed:
• transcendental’s view: quality is something that you
immediately recognize, but cannot explicitly define.
• user’s view: sees quality in terms of end user’s specific goals.
If the product meets the goals, it exhibits quality.
• manufacturer’s view: defines quality in terms of the original
specification of the product. If the product conforms to the
specs, it conforms quality.
• product view: suggests that quality is measured with respect
to inherent characteristics of the product.
• value-based view: measures quality based on how much a
customer is willing to pay for a product.
Different views of Quality

21. BITS Pilani, Deemed to be University under Section 3 of UGC Act, 1956
• Prepare a document describing quality attributes that
might define quality for buying an attendance monitoring
system for your organization.
• List (and explain) atleast 3 quality attributes.
• Identify (and explain) sub-attributes.
• List down questions to be answered for measuring the
listed sub-attributes.
• You may consider to chose any other system or your
choice.
