      1. Thanks! I am am also trying to get registered for your webinar on cog tool through UXPA. My membership status is still pending. I have emailed them about this.

  1. Oh, and certainly you can use CogTool to compare interfaces — that’s what it does best!
    Until I get all the papers imported into this site, you can find a lot of information at my IBM Publications site:

    In particular, you might want to look at the following papers listed on that site:
    Deploying CogTool: Integrating quantitative usability assessment into real-world software development
    Using predictive human performance models to inspire and support UI design recommendations

    Hope this helps.

  2. Hi Bonnie,
    What is the severity level of usability problems detected by GOMS? e.g Heuristic evaluation can detect both severe and less severe issues.

    1. There is no absolute definition of severity levels – it depends on your business goals. GOMS and CogTool (because it is a variant of GOMS), give you the amount of time a skilled user will take to perform a task on your UI design. If your UI design is 10x slower than your competitor’s UI to do the same task, then it is probably “severe”. If it is 10% slower? Well, that depends on whether your system is giving other value to your customer that makes them happy enough that it will be OK to be 10% slower.
