Previously, I had mentioned DIF (difficulty, importance, frequency) Analysis as a tool that I used in the military to determine if job tasks required training. I finally got around to creating the expanded model in a digital format, so here it is.
In making these tools available online some people ask if I’m giving away some secrets to the trade. I don’t think so, because these are pretty basic tools which I’ve been using for over a decade and many others use as well. Also, the world of work is getting to a point where performance improvement may not be the best approach. In knowledge-intensive workplaces, procedures and tasks can’t be easily quantified. Tools like DIF analysis only work when there are similar jobs done by several people. They won’t help in a creative work environment like a design shop.
My own interest is to develop new tools and methods, beyond human performance technology and instructional design. Methods like online personal knowledge mastery are of current interest.
