We start with requirement gathering phase that refer to understanding the user and what her goals are and what are the current practices. In this phase the designer aims to understand how the user is currently completing the task

In the second phase, designing alternatives, we are able to develop novel interfaces to successfully complete the task. Once you understand the users, their goals, and their current practices (i.e., the problem space) you are able to take this data and develop various design options that will improve the user experience.

Techniques for modelling the novel designs before a final version is produced in the third phase, the designer takes the best designs from phase two and actually builds models or prototypes that the user will be able to engage with. These models meet core aspects of the task.

In the fourth phase, we take one of the designs from phase three and we actually test the system’s usability and usefulness with either users or experts who can provide us with feedback about how to improve the system.
