One of the best and important parts about the user experience engineering is the development process. It happens to start right from the basic or we can say, the base. And it keeps on carrying to the upfront making everything clear and smooth in the functioning of every process. So, the best way to map out all the possibilities that tie together the three main things research, engineering, and design. Be it start-ups or a founded company all you need to know about is the way you need to steer the process of the firm. Right from designing to applying. But then these three fundamental aspects do chain a few questions to them, which includes why do we need it? When do we need it? And what happens if we don’t use it? Now to answer the why part, there is the research, to answer the, what part there is design and for the how we have engineering. So this is very important for a firm to know the exact answers to these questions. Knowing so, will help them in having the best user experience engineering.
