Benchmarking A Definition

• Benchmarking is about identifying and measuring
  best practice processes that work elsewhere and
  then emulating them.
• The aim is to reduce duplication by learning from
  others who have already found the solution.
• It is about
• Understanding your weaknesses
• Comparison with your peers
• Note that best practices are constantly evolving.

  services

Implementing A Benchmark Survey

• To implement your own WebWatch- style benchmark
  across a community you can simply examine
  WebWatch articles and adapt the HTML for your own
  use.
• Further details at lthttp//www.ariadne.ac.uk/issu
  e29/web-watch/gt

• Technique Used
• Use the Web service on a site
• Copy URL into template
• Determine URL structure
• Use as basis for use with other URLs

Next Generation Tools

• There is a need for sophisticated testing tools
  which
• Use rules
• which allow you to ignore types of errors
• can output special error messages for personal
  errors
• can be time or area dependant
• Can check all aspects of your Web site - network,
  machines, processes (code) and individual files
• Can mimic Web browsing behaviour (browsers,
  cookies, etc.)
• Examples of such tools include WebKing,
  Freshwater Software, WebCriteria,

23
Independent Testing Services

• Occasionally it may be necessary to outsource
  testing.
• The benefits of doing so include
• Saving time and resources
• Tapping in to outside expertise and experience
  dedicated to testing
• Testing tool independence
• Objectivity

• Would you be interested in a neutral 3rd party
  testing your Web site? If so, how much would you
  be willing to pay?
• Would you be interested in a body in the HE/FE
  sector carrying out a benchmarking survey and
  comparing findings with your peers?

24
Discussion

• What WebWatch surveys would you like to see
  carried out?
• Is there a need for a government funded
  WebWatch-type survey across all institutional Web
  sites? If so
• Who should do it?
• How comprehensive should it be?
• How would it be funded?
• Would you prefer to outsource your testing?
• Would you be interested in benchmarking
  regionally?

25
Conclusion

• Different tools give different results and
  results can be limited. The results should be
  analysed carefully - like statistics
• Independent testing services can be beneficial
• Comparison is useful
• However a league table is not enough, for this
  type of evaluation. To have a point there should
  be follow up action
