One of the things that I am really excited about in the draft version 2.0 of the BABOK is Chapter 8: Underlying Competencies. This section acknowledges important behaviors, characteristics, knowedge and qualities that a BA should have but that are not exclusively owned by business analysis.
The competencies are categorized into 1) analytical thinking and problem solving, 2) behavioral characteristics (like ethics and trustworthiness), 3) business knowledge, 4) communication skills, 5) group interaction skills, and 6) software applications.
Each of the categories is broken down with a purpose, definition and effective measures. This section of the BABOK will be very helpful for BAs to get some direction/guidelines around what is expected of them.
