The ISTE approach to usability testing

The ISTE approach offers a new method of concurrent testing that is less time-consuming than usual. In addition, it helps catch the user in the act and the scores show almost immediately whether the user has processed the manual as intended. In the ISTE approach, the main information subtypes in a manual are coupled to their intended and unintended effects on users. Research has shown that the ISTE approach yields reliable and valid findings. In addition, it has been found to be versatile and easy to apply, and it provides valuable insights on the usability of a manual.
