Usability is a crucial component of the field of user experience design as a whole and is generally regarded as ensuring that products are efficiency of use, ease of use, and satisfaction or enjoyable from the users perspective.
Whether it be related to digital products such as websites and applications, electronic equipment appliances, or many other items that we may encounter during everyday life, usability involves optimizing the interactions people have with products to enable them to carry out their activities quickly and easily.It's actually a subset of the user experience. So usability simply looks after the efficiency of a user, the ease in which the user can complete their task, and how satisfied they are with that task. It includes the experience the user has, the emotions and motivations that come with the user using the product. There's an international standard for usability. It's ISO 9241 part 11. So the standard talks about the user, the task, the equipment, and the environment. The most effective way of improving the usability of a product or service is involving users, There's a methodology known as user centred design, which is all about putting the user at the centre of the design process.
