Jakob Nielsen's Alertbox for October 18, 1998:
Despite these miserable statistics, users do benefit from the Web since they spend most of their time on the good sites. But the odds are against them when they want to try something new. And the odds are against any company that wants to put up a website: in my estimate 90% of commercial websites have poor usability.
The recent Forrester report is particularly interesting because it tries to identify the reasons for the many bad corporate websites as well as the impact on a company from having a bad site. Many of Forrester's conclusions are similar to my writings in the Alertbox since 1995 and the report provides additional supportive data from large corporate Web projects.
For the report, Forrester interviewed 25 executives in charge of various companies' Internet efforts. Most had very few design goals for the site, though 56% did mention "fast performance" as a goal (bravo!). 24% of sites conducted usability testing: this is more than I would have expected and probably reflects Forrester's bias toward bigger and more well-funded projects. (Of course, this data implies that 3/4 of large sites are managed without any usability data: essentially poking blindly into the design space.)
The report provides considerable detail on the economic impact of these and other problems. In summary: many millions of dollars lost for a large website.
The report predicts that Web solutions agencies will soon include usability engineering as one of their core offerings. I definitely agree, though I also think that the client needs to take an active role in auditing the usability of the deliverables.
Clients should insist on usability testing of all Web designs: The quality of the proposed usability process is one of the few ways a client can judge the quality of the end result while still in the proposal stage. A proposal without usability engineering milestones (or with poorly defined or misguided methodology) will result in a poor site most of the time (unless you are in the lucky 10%).
If you work at a big company that subscribes to Forrester's service, I strongly recommend that you get a copy of this report. It will be very useful in avoiding disasters in future Web projects.
