I joined as a business analyst in a company. i don't have any experience in this field. Where do I start?
Run, don't walk to the nearest computer. Do a search on business analyst certification and then on business analyst courses. You will probably have to take some courses before you attempt the certification tests. You might find local colleges that offer courses or an online college, such as Villanova. If you come from an analytical background, such as engineering, science, or business, you should have little trouble picking up the basics. The certification can be valuable when you have little or no experience. It proves to employers that you have a working understanding of the subject.
