To the original reader, I would ask how established business analysis is in your current organization. If it has a good foothold, that is great news and where you should start. If not, it is up to you to raise awareness about BA within your organization. The references that Aaron sited can help you with this as well.

Finally, you may decided that the position you want does not and will not exist in your organization. If you have to make a move, the key is networking and having a clear picture of what you want and what you can provide. You can tailor your resume to highlight the BA work that you have done, even if you don’t have the title. Those of us hiring BAs are used to seeing this.

Good luck and don’t give up!
