I think the demand analyst is a comprehensive post, who can do design, project management, pre-sales and so on after engaging in demand analysis. This is a profession that needs training very much.
I have been engaged in demand analysis for four years. From my personal cognition, the career development of demand can develop in the direction of consultation, because there are three golden occupations: "doctor, lawyer and consultant", and they are becoming more and more popular with age. Of course, to meet the demand, we must be expert, have the strength, work hard, and we will certainly gain something in the future.
