The first thing we have to take into account is that the software is used by humans and because of that fact, the software and the systems must be easy to learn, efficient to use, effective and simple to remember. The developers and the stakeholders should think about those factors when they are designing and developing a new software system.
Usability is needed to measure the quality of the user experience when interacting with a product or a system. It depends on several factors such as the degree of satisfaction of the user needs or the easiness level for navigating through the system.
The importance of usability applied to software products can make the difference between performing a task correctly or not, helping the user to perform it or being a nightmare. Usability can be the key factor for success or failure of a product.
There are benefits for both sides. The providers can reduce the amount of hours and costs used for development, training and support. For the users’ point of view, they will enjoy interacting and using the product, achieving goals, working effectively and efficiently and their satisfaction.
The investment on usability is a powerful weapon for the companies, if it is correctly used the profits can be increased and also the customer satisfaction, customer confidence and performance while working with the software. If the customer is satisfied with the program and enjoys working with it, he/she will keep using it and probably recommend it. This opens the market of the companies and also reduces their costs as the software has no errors and they don’t need to spend either money or time on debugging and fixing errors.
As a conclusion, including usability on the development process at the beginning can be an investment but at the end will generate profits and benefits for the companies providing the software and also for the users who will obtain better products.
