Usability is the ease of access and/or use of a product or service. Some products focus so much on the product itself and doesn’t consider whether customers can use that product easily or not. No matter how developed it is at the end of the day, if the customer cannot use the product or service comfortably, you will not be able to meet their needs. The level of usability of a product is determined by both its features, the context of usage and the user’s needs.
