In our study we with a Technology Acceptance Model (TAM) we want to use Usability at the place of Perceived Ease Of Use (PEOU).
- PEOU is defined as the degree to which individuals perceive how easy it is to use technology (Davis et al. 1989)
- Usability is defined as "The extent to which a product can be used by specified users to achieve specified goals with effectiveness, efficiency and satisfaction in a specified context of use" (Jokela et al. 2003:11).
I would argue that usability is equivalent to PEOU, where PEOU has an explicitly subjective character (perception) and usability is somewhat broader and more objectively conceptualised (with its own subjecitve component in questions of surveys or interviews).
Hi Egon. I would agree with you if you take the whole context into consideration. Then, yes, PEOU and usability can also be seen as what the user experience is (UX) is like. However, UX, PEOU and usability could also have bad outcomes, or side affects. For example in relation to TAM, the experience might be good and the software might be easy to use but they might not want to use it as they don't perceive it useful.
Contextually, PEOU can represent usability,
PEOU (the degree to which a person believes that, using a particular
system would be free of effort)
Usability (set of layout, structure, arrangements, typography, and many other properties that makes website simple and easy to use) - [Choros, K., & Muskala, M. (2009, October). Block map technique for the usability evaluation of a website. In International Conference on Computational Collective Intelligence (pp. 743-751). Springer, Berlin, Heidelberg.]
The core aim is a user's ability to utilize the system with ease.
You're on the right track
My question to you Egon Werlen is what is the context? There are simple tools to measure the usability of a system. TAM might be an overkill for what you are looking for.
