As it says on the title I am looking for a career change to become a business process analyst, and was looking for some advice on things to read and jargon to learn. 

I have started looking at the IIBA website, and have begun browsing the modern analyst website to gain some background knowledge.

I became interested on process improvement following three years spent on continuous improvement roles in manufacturing. I started down the path of Lean Six Sigma black belt, and realised that I wanted to do process improvement full time. The broader nature of the role, and the easier transition into non manufacturing roles, are the major factors in me looking into business process analysis. 

Any help/advice is appreciated.
