Hi there,

I am doing some prototype testing on a set of navigation paradigms and
as a preliminary step, we are looking to narrow the candidates down
from about 7 to 3. We will be ranking each against a set of
qualitative metrics to make this reduction in scope more objective.

A little background: We have a suite of legacy desktop apps that were
first designed and built about 12-15 yrs ago. They were initially
built for the Mac, and later used the Altura libraries to port them
over to the PC. The interaction model is very evolved, internally
consistent, and in many ways has defined the way that users do their
day to day job. In the last couple of years, a complimentary suite of
web-based applications has been introduced. A good deal of design and
usability testing went into these DHTML based applications. Recently,
we decided to move in the direction of rich, web based applications,
using ULC as the foundation for GUI deployment. This has opened the
flood-gates on the interaction model, as we are no longer limited by
the request/response cycle [insert plug for RIAs here...]

We have defined a set of preliminary metrics, and I was hoping to open
it up for comment prior to diving into this process.

Our metrics:

Contextually Clear
Consistent: Desktop Apps
Consistent: Legacy Apps
Separation of Navigation from workspace
Specific to task at hand
Flexible
Configurable
Efficient
Modern
Localizable
Implementable

I am sure that there is some resource out there that has a more
standard set. Or maybe there isn't... Input at this stage would be
invaluable.

Thanks!
Clay

How about GOMS analysis for speed? Also, are you using an objective and
quantitative measure of efficiency? Information-theoretic efficiency?
Keystroke efficiency? Are they modal? monotonous? habituating?
