VIMM Model

VIMM Model for better usability

What is VIMM Model ?

VIMM stands for Visual, Intellectual, Memory and Motor testing. These four simple concepts covered in the model, account for 80% of the usability issues.
The VIMM Model is a way to focus on how usable your product or website is for a user. It dives deep into understanding which aspect comes naturally to the user and what requires a decent amount of work or thought process from his end.

The end goal of using this model is to ‘reduce the load’ of the user in these four key areas. Let's break down the concept…

Visual load refers to visual elements in the designs which forces the user to put more effort in visually identifying the element. we can optimise visual comprehension following these instructions.
