A car’s steering system enables the car to turn and its suspension system smooths out the ride. However things can go wrong, making the ride rough or steering difficult or dangerous. This means time to repair. Many types of steering and suspension systems have been used to control cars. Older cars use mechanical suspension that relies on springs and shock absorbers but new cars use hydraulic cylinders called struts. Besides this, many of today’s cars rely on rack and pinion steering. Without proper care, a car’s steering system should give 80,000 to 100,000 miles of smooth turns

Ranking severity is often subjective although influenced by years of experience. Some calculations can be made when determining the affect on revenue or profitability, but branding and the like is always subjective.

I provide such ratings not for my own purposes, but for the benefit of the stakeholders. Those that determine priorities should be given some guidance as to the level of severity each issue has on the company's bottom line.

Great post.

I find frequency to be a tough variable to measure. Since we typically work with such small samples, I don't trust the frequencies that are derived from usability issues identified with n's of 5 or 6 or even 10. So I guess, rightly or wrongly, that I tend to discount frequency. I don't totally disregard it; I do factor it heuristically into my thinking about an issue. But I typically don't measure it as granularly as others may.

Paul, how do you factor how frequency into your overall prioritization of usability issues? For example, you may observe low or medium issue in frequently performed task. That could likely merit more consideration than a medium issue in a very infrequently performed task.

As a sometime home-brewer I can get behind metric that was originally intended for rating beer.

Agree very strongly. Had a go at scales based on the National Beer Scoring Scale from CAMRA

Like the scale above but prefer users doing the rating to me doing it.

I do rate findings and think it's important to do so, but I've used the same “standard” ones for so long that I rarely give thought to the scale. I appreciate, therefore, the topic and like how you focus these on business/financial impact as in the end, that should be which usability elements get tackled first.
