Quality standard of interaction design
For most proceeding projects in our organization, we all meet the same
problem -- how to evaluate the quality of interaction design results of a
specific web-based service. Are there any standards existing in this field?
Or we have to do many usability testing to any interaction modules in any
iteration procedures?
Actually, the quality evaluation request is from the management board of the
company. They wanna control the quality of every ring of the chain.
I had ever thought that if I could use design pattern library as the
standard. By evaluating the use ratio of design patterns in one product(of
course they will be used to deal with those general design problems), maybe
I can tell the quality of the product.
Do you have any practice in this evaluation field? Any materials refered?

Hi, Stephen! If you'd ask me, quality of the web-service based on the
use of patterns will be only as good as the patterns are; but better
use some kind of "standard" than no standard at all!
If you really want to stick the word "standard", the only one that
comes to my mind now is the ISO 13 407
(http://www.iso.org/iso/iso_catalogue/catalogue_tc/catalogue_detail.htm?csnumber=21197)
which establish Human-centred design processes for interactive
systems; my guess that right now, it only set standards for the
process of the designing interactive systems, not to the interactions
themselves... but I could be wrong (anybody else care to chime in?)
Anyway, last I heard the sub-committee of the International Standards
Organisation ISO was looking in the better defining the standards
(http://www.usabilitynews.com/news/article4636.asp)... let's wait
and see!

Hi Stephen,
Maybe you ask a interesting but never will get result question. As
designers seems never agreed (and this will continue for years) on
what's good interaction design until now. If there's some, it might
list as,
> Good design should fit into end user's life
> Good design should improve the end user's life
> ... ( bunch of this )
And also some guys give more pragmatic ways to measure it,
> roi measurement by after launch

I guess it could help to define the quality of what exactly are you
looking to evaluate. I can't think of valid examples, but they'll
be close to User Satisfaction, Task Accomplishment Time, or so, I
guess.
When it comes to design patterns, it seems futile to evaluate
anything to them. To give an example it would be like defining an
automobile's quality levels by assessing design patterns used, but
then, hinged doors, round steering wheels, 2-wheel steering, 5-seat
layout, 6-cylinder engines are all design/engineering patterns, and
that itself does not make the car a better one, unless, beforehand,
you define some values to be evaluated against: occupancy number
(then a 5-seater might be compared to a 7-seater), etc.
Seems to me.

Hi Stephan,
Jarod is spot on in terms of designers never agreeing on what's the correct
interaction but in my opinion a good design critique can lead you to some
conclusions.
Here are couple of resources about design critique:

Patterns can help with consistency, and design heuristics, tenets,
guidelines, walk throughs and critiques can all help in improving a
design; but I don't see anyway to truly evaluate quality of
interactions without actual testing.
I suggest setting measurable design goals at the start of a project -
for task success, time on task, user reported satisfaction, user
confidence in task completion, etc. - so both qualitative &
quantitative measures.
Management / clients can review and signoff on the goals at the start
as being the desired set to achieve, and the goals can be tested
against throughout as the design matures - from wireframe to early
functional prototype, alpha, beta...
For an updated site or service ideally the current offering would be
benchmark tested against the same measures so improvements (or
losses) against the set goals could be tracked.
