“As a rough estimate, a 2-star average across 68,418 reviews means that 40,000 users gave the application a 1-star rating. Given the 90-9-1 rule for social design, most users never bother reviewing products, so 40,000 low scores represent at least half a million dissatisfied customers.”

IA heuristics
March 17, 2010IA heuristics (comes handy for review)
- Does the site structure match the tasks to be performed by the user?
- Does the apparent site complexity and functionality match the intended user need?
- Is the structure designed so as reduce the total number of navigational steps needed to reach the desired page?
- Are frequently needed and critical pages located near the top of the site structure, requiring a small number of clicks from the homepage?
- Does the structure convey an appropriate metaphor that facilitates user’s understanding of the site?
- Do the navigational labels provide meaningful, unambiguous summary of the pages?
- Do the labels use familiar and consistent terminology?
- Are the labels distinct from one another?
- Do important keywords stand out in the labels?
- Does the site promote learning of the location of pages in the site structure?
- Does site design build on our prior learning and experience of the intended users?
- Does the layout of the navigation facilitate visual scanning by the user?
- Do the number of pages per navigation level and the number of levels in the site structure optimise navigation time?
- Has random or arbitrary ordering of pages on a particular level in the site structure been avoided?
- Are pages on a particular level presented in a logical order to facilitate scanning?
- Are pages on a particular level ordered to reveal structure and relationships among them?
- Does the order of pages agree with the user’s expected ordering?

Web standards
June 6, 2008- All web pages should contain: title, site-identifier with link to
home page, update date, navigation, contact, content p.120 - Standards “allow graceful degradation” apparently goes back to Jeffrey
VEEN, The Art and Science of Web Design, 2000, New Riders - Why it’s good to stick to conventions and difficult to create new
communicational clues p.94 (sidebar)

Nielsen’s usability principles and heuristics
June 5, 2008-
Visibility of system status – always keep users informed about
what is going l, through providing appropriate feedback within
reasonable time - Match between system and the real world – speak the users’
language, using words, phrases and concepts familiar to the user,
rather than systemoriented terms - User control and freedom – provide ways of allowing users to
easily escape from places they unexpectedly find themselves, by
using clearly marked ‘emergency exits’ - Consistency and standards – avoid making users wonder whether different words, situations, or actions mean the same thing
- Help users recognize, diagnose, and recover from errors – use plain language to describe the nature of the problem and suggest a way of solving it
- Error prevention - where possible prevent errors occurring in
the first place -
Recognition rather than recall – make objects, actions, and
options visible 8. Flexibility and efficiency of use-provide
accelerators that are invisible to lovice users, but allow more
experienced users to carry out tasks more quickly 9. Aesthetic
and minimalist design-avoid using information that is irrelevant
or rarely needed - Help and documentation – provide information that can be easily
searched and provides help in a set of concrete steps that can
easily be followed

Heuristic evaluation of websites
May 19, 2008According to Nielsen etc., users ignore approximately 80% of the content of a webpage. Doesn’t really surprise, does it?
Scannability of pages becomes more and more essential and is on the top of my list for heuristic evaluations. Other key criteria: orientation, consistency, relevance, and controllability.
- Where am I, what do I get?
- Site ID
- Communication of site goal (e.g. in tag line)
- How can I navigate?
- Signposting: Where am I, where can go, where have I been? (e.g. breadcrumbs)
- Amount of menus manageable? Competing navigation systems?
- Categories and subcategories sensible and logically coherent?
- Consistent labels?
- search function?
- How do I find my way within the page?
- Screen real estate: content first?
- Overall hierarchy apparent and sensible? Visual hierarchy, Headers, subheaders, lists
- Granularity of content chunks consistent?
- Makes content sense as a ‘narrative’ or answer to the user’s interest?
- Visual weight of irrelevant elements (Ads, banners etc.)
- General usability
- Adheres to conventions for layout, navigation and technical features?
- Visual cues to support navigation and communication? Links clearly highlighted?
- User centred approach: personalisation, control of page layout, reflection of user needs?
- General accessibility
- Standard compliant with W3 standards?
- Clear structure?
- HTML syntax?
