Final reports and presentations
You have to produce 3 things: 1 – Formal project report• 10 page ACM conference publication format• http://www.sigchi.org/chipubform/
2 – “Glossy” report selling the site• Show the board why this is a good design• e.g. Why users would want to come to the site and trust it
3 – Group presentation• Explain your reports• Highlight the findings that you think are particularly important

Glossy report
No particular structure “Sell” your site to your client Explain aesthetic choices, etc. Cover anything you want to draw attention to that is not in your formal
report

Formal report
This is a project report, not a usability report Structure your report like a scientific report (see earlier lecture notes) The aim of the report is to show that:• You know what factors affect the usability and accessibility of a web-site• You set up appropriate experiments to inform your re-design process• You can explain and justify all design decisions made• You can identify and recommend potential improvements to your site

Example formal report structure
Abstract • Executive summary of the report
Introduction• What you are writing about and why• What research questions you are asking (ideally posited as hypothesis)• Example hypothesis: The revised site offers faster task completion times
than the original site• Example hypothesis: The revised site is more accessible [define this!] than
the original site
Background• Talk about the design of the original site• Why did you design the site the way that you did?

Example formal report structure
Method• Describe each of the experiments that you performed on your site • Examples: Heuristic analysis, pilot study, exclusion analysis, accessibility
checkers, personas, etc.• Describe how you did each of these (e.g. describe the users, etc.)• Describe your final “verification” user trials• Include user profiles (ages, etc.)
Results• Describe the results and observations from your user trials• What data did you collect?
• Quantitative and qualitative

Discussion• What did you learn from the user trials?• Did the data you collected help you answer the research questions that you
posed? • [Note: they should have done]
Conclusions• Did the usability and accessibility of the site improve?• Did the different experiments that you performed help improve the design of
your site?

Further work• Are there further studies you would like to perform on your site?• What further changes would you make to the design of your site based on
your user trials?• Explain and justify your answers to these questions
