Have you ever struggled to explain to someone what you do? Not just to that distant cousin at the family Christmas party, or the random person you are chatting with in line at Starbucks; but people who actually work within your organization? Or even worse, the senior people who are going to be taking part in your project and who have no idea what a Business Analyst does?
Have you mumbled something about projects, processes, and software? Maybe mentioned requirements elicitation, analysis, and documentation? The problem isn’t that you don’t know your job, the problem is that your job title is wrong. We are not business analyst’s.
