Whilst reading this blog post by Peter Merholz, which commented on the ACM Interactions article by Microsoft’s Dennis Wixon, Evaluating usability methods: Why the current literature fails the practitioner (which I’ve downloaded but haven’t read yet).
I came across a comment post by Beth Mazur from IDBlog on the useful paper by MAYA Design, Inc. and published for the 2001 UPA (Usability Professionals’ Association) Conference, in Lake Las Vegas.
The paper, An Integrated Method for Evaluating Interfaces (free to read) shows Maya’s process and methods when integrating user research, heuristic evaluation, affinity diagrams, cost-benefit charts, and recommendations for use in planning both short and long-term improvements to interfaces.
It is a useful and interesting read.
