From your first impressions, write down what first comes to mind as to what is good or bad about the way the website/system works. Then list (i) its functionality and (ii) the range of tasks a typical user would want to do using it. Is the functionality greater, equal, or less than what the user wants to do?

Usability: A measure of a user’s ability to arrive on a site, use it easily, and complete the desired task. Remember, we’re designing websites, where there is flow, rather than focusing on page design and assuming everything will flow later.

Explanation:

1.) It should be easy for the user to become familiar with and competent in using the user interface on the first contact with the website. If we take a travel agent’s website that a designer has made well, the user should be able to move through the sequence of actions to book a ticket quickly.

2.) It should be easy for users to achieve their objective through using the website. If a user has the goal of booking a flight, a good design will guide him/her through the easiest process to purchase that ticket.

3.) It should be easy to recall the user interface and how to use it on subsequent visits. So, a good design on the travel agent’s site means the user should learn from the first time and book a second ticket just as easily.

4.) We also consider user's experience

5.) The hosting server of the website

6.) Usability: A measure of a user’s ability to arrive on a site, use it easily, and complete the desired task. Remember, we’re designing websites, where there is flow, rather than focusing on page design and assuming everything will flow later.
