Techopedia Explains Hallway Usability Testing
The idea behind hallway usability testing began as an alternative to hiring trained or certified personnel to test a particular software or technology product. The idea is that you can go out and grab random individuals passing by an office in a hallway and get them to test a product being developed. Another way to think of it is that random individuals are gathered from the street and then assembled in the hallway before having them test a product under development.
Some experts believe that using hallway usability testing can reveal up to 95% of usability problems with a given interface or product. In some ways, the principle of hallway usability testing is similar to the old idea of "putting 1000 monkeys at 1000 typewriters" — there is the commonly acknowledged suggestion that, by doing this, companies can effectively test systems without investing in a core group of certified testers or other users whose skillset or experience may be expensive. In a lot of ways, hallway usability testing is like developing a beta testing phase, where the product or interface is constrained to a random sample group before it is released to the public.
