What does QA give?
• Quality’ means your project is ‘useful’ without ‘quality’ you may have little to
offer
• ‘Quality’ can help to future-proof projects
• But ‘quality assurance’ needs
documented standards and best practices
to be meaningful
• ‘Quality’ & ‘Best Practice’ can be
considered in terms of being ‘Fit for
Purpose’

Why is QA needed?
In the past JISC had standards-based
philosophy but:
• Approach of "let a 1,000 flowers bloom"
• Diversification as no killer application
Things are different now:
• The Web is the killer application
• There is now a need for interoperability (now
self-contained independent Web sites)
• There is a need for publicly-funded services
to be seen to provide value for money

What is Quality Control?
Quality Control (QC) is the implementation of
regular testing procedures against your
definitions of quality and more specifically the
refinement of these procedures
• Formal use of testing
• Acting on the results of your tests
• Requires planning, structured tests, good
documentation
• Relates to output - Quality Circle
• Standards - ISO 9000 & BS5750
• however there is currently no such
standard for Web sites
