When testing the draft usability it is important that know who your primary audience is and what level of knowledge the reader has. Learn how the draft would make the reader feel mentally and see if it makes them happy or frustrated. Then you finally get contestants to actually sample your usability. The goal is to absolutely eliminate bias so that everyone can read it and not want to talk bad about it because you bashed a product that they used before, so that they do not try to find every problem with your product and not want to tell their friends about how great the product is. The Author makes the instructions as simple as possible so that it can go to any age group or gender.
