Usability can be seen as a quality attribute which assesses on how easy the user interfaces are to be used. Moreover, the word usability can also known as a metoh which is being used for improving the ease of use during the design process. There are five quality components that can be seen which are Learnability, efficiency, memorability, errors and also satisfaction. Indeed, all of this components must be look through so that the usability of the interfaces can be satisfied hence, can be improved once it is being needed.

The website that have been chosen to be evaluate is the Malaysian Online Shopping website , Lelong.my (www.lelong.com.my) and also mudah.my ( www.mudah.my)

Lelong.my

The learnability of the website can be seen being easy to be gained. As such, the basic tasks such as for the first time user to used the website, the user can be seen have their easy way on how to surf the interface as the interface is being build as simple for the user to used.  The design is not too complex indeed. User can search what they wanted to have by just entering it in the search text box that have been provided in the website. See example below-

Moreover, the font that is being used in the website also not being efficient as it used different type of font in every pages. A part from that, the website also can be seen used a several type of colour in the interface design. Indeed, the colour that has been placed in the website is being appropriate for the user. It is because, as we can see in the website, every pages have a same usage of colour for the header, font and background of the website. However, once the user learned and know about the design, it will definitely ensure their performance of task while using the website.See example below-

Memorability:-

If the user have an experience of using sort types of website, hence the errors can be avoided. However, for the user that might not have an experience of using it, they will tend to have a problem which will then lead them to experience error while using the website. Indeed, numbers of errors that they make which perhaps happens too many times should have its own recovery or help from the website towards the user. This is to ensure that the errors that happens can be recover easily by the user.See example below-
