I've been reading Return on Investment for Usable UserInterface Design: Examples and Statistics; it quotes:
"...usability techniques helped cut development time by 33-50%” (Bosert, 1991)
Although I can see some reasons why this would be the case but I feel like I'm still missing something important. What specific reasons do you know of (or suspect) that would make this statement true?
Reasons I can think of:
- Easier to understand the flow / intent of the application (or site) - so its easier to develop (just like users will find it easier to learn).
- Quicker to test (and testing overall more effective).
[feel free to re-tag this if you know of any better ones]
