Measuring Percieved Website Usability 2007 Jianfeng Wang & Sylvain Semeca Journal of Commerce 2007 This paper tried to develope a short reliable and valid percieved website usability measurement scale(parimonious scals usable across all websites). There is an argument to be made that users experience a website before they commit to use it. Usability defined as how well and how a user, without training can interact with an information system of a website. A website must be compatible with characteristics of human action and perception, but also with users cognitive skills in communication, understanding, memory, and problem solving. In the usability metrics section of the paper it states there are five distinct approaches of usability testing: 1 Testing, 2 Inspection 3 inquiry, 4 Analytical modelling, 5 simulation. All dependent on subjective assessments in the form of user judgement. There are three dimensions of usability: 1. Ease of use 2. Navigation speed 3.Interactivity This paper also states the the fact a positive correlation exists between the usability construct and attitude towards the website. The method used involved 350 students asked to go to transactional website and perform set tasks. It tried to focus one dimension at a time. Future directions suggests looking at testing the scale in relation to different contexts such as informational websites destined for professional buyers. This scale is good in identifying which of the dimensions of a website need tob improved. The limitations of the study are that it was used only one website and mightent have great generalizability. Also cannot be certain users experienced all functionality of the website. future directin of research suggested by this paper could be look at subjective versus objective approaches of usablity evaluation.
