Hearing childhood teenage professional hero Andy Budd speak at #lwsux last month confirmed many things that I already knew, and introduced me to even more things that I needed to be more aware of (read my full write-up).
The one thing that really got me was talking about the "low-hanging fruit". It's a pretty simple concept, as a consultant, much of the benefit you will bring to an organisation, in improving a system's design, will be painfully obvious.
What's the lesson here? Take the easy usability problems and solve them with best practices. Test as you go, there's no need for large-scale user testing unless there's a specific problem that you've been asked to solve. The simple solutions to simple problems solve most of the issues of user-friendliness within a system, and a good bit of IA generally does the rest.
So, take the easy option!
