I know it’s been over 2 months since I started part one in this series, but my life has been very busy, but I’ve had many opportunities to think about this and other issues at CHI2008 and in my work.

I’ve been doing some consulting and usability work for medium-sized organization. Part of that work has included some usability work, and I have tried desperately to incorporate some UX ideas and methodologies as well, with very limited success.

What seems to be the theme in all that I do is that usability ends up being post design phase work, and UX MUST be part of the design phase, preferably in the earliest conceptual phases in order for it to really work. As an outside consultant or evaluator it is almost impossible to implement any meaningful UX ideas or methodology no matter what phase of the work you are brought into if the organization is not open to it and/or does not understand the power of it.

Almost everyone has a vague idea of what usability is, and it is generally thought to be positive, although there are a lot of misconceptions about it. It is easy enough to run usability tests at all phases of design and implementation and have significant ROI on it in terms of improvement of the product, bottom line (if applicable), and client satisfaction.

So what is usability in the age of UX? I guess the easy answer for me is that it is that usability is part of 2nd wave HCI, and UX is part of 3rd wave HCI. Those of us working in 3rd wave cannot forget about 2nd wave ideas and methodology, as they are vital, but the promise of 3rd wave is that there is so much more beyond it.

I’ll post more on being a Luddit later (from part 1).
