Experience is the key to success when it comes to a business analyst. Many great business analysts did not even go to college. If they did it was not in the field of business but technology. A business analyst can earn a degree. There are certification classes one can take to hold the title of certified business analyst. Most have learned from experience not from books.
A good business analyst is one who has prior experience in the business world with trouble shooting. They will be able to assess a business proposal or project and determine needs from data gathered. A book or white paper may not tell a business analyst what needs assessments to to prepare. Only experience can do that in certain businesses. To better understand what degree a business analyst must have consider it only takes 8 weeks to become a certified business analyst.
2 months of study can explain what the job description is and how to implement it. When you put it in those terms, it may be a little unnerving to some. Those 8 weeks are crammed with information straight from a text book. The real world is slightly different.
Someone with business savvy can figure it out. The problem lies in implementing the plan of action. The reputable business analyst will be able to speak with management and other stakeholders to hear what problems and solutions have been ascertained. These issues may or may not be the root source of the conflict. The business analyst can determine this. He or she can weed through what management thinks is necessary information to glean the truth.
He or she will be able to drop in on IT and see what their take on the problem is. The business analyst will also speak to other low end users who know more about the application of the program. This is where other departments fail in providing what works and what does not compute with real life scenarios. Does someone need a degree or license to understand the issues of business?
No. Does it help to have an understanding? Yes. It certainly looks good on a resume to list degrees and certifications. Past experience and a portfolio of solved issues will go farther than any framed paper.
