What they found is that the system performed very well. Two doctors working out of a microclinic could meet 80 percent of a typical patient's needs. With a hi-def video conferencing add-on, members could even link to a nearby hospital for a quick consult with a specialist. Patients would still need to travel to a full-size facility for major trauma, surgery, or access to expensive diagnostic equipment, but those are situations that arise infrequently.
If that 80 percent number rings a bell, it's because of the famous Pareto principle, also known as the 80/20 rule. And it happens to be a recurring theme in Good Enough products. You can think of it this way: 20 percent of the effort, features, or investment often delivers 80 percent of the value to consumers. That means you can drastically simplify a product or service in order to make it more accessible and still keep 80 percent of what users want—making it Good Enough—which is exactly what Kaiser did"“So the issue is how you cut out some of the middle men in these communication loops,” she says. “And how do you shorten the timeframe between when a nurse needs to talk to someone and when she actually gets to talk to that person, then either make a care decision or figure out what needs to get done next.”
Brian Whitworth (Institute of Information and Mathematical Sciences, Massey University, Auckland, New Zealand) has some very interesting papers on evaluating 'Socio-Technical Systems' on a multi-criteria basis. Here are three (some written with others):
