I came across this graphic in one of the training programs I participated in not too long ago. I am interested in becoming a CBAP (Certified Business Analysis Professional).

I don't see myself as fitting exclusively into the PM role or the BA role, and the reason for this is because if you can perform the PM role perfectly and still have a failed project. Similarly, you could perform the BA role perfectly and also fail with the project.
To be fair, I think that the PMI would disagree with this graphic on some points. I think PMs must deal with stakeholders and the graphic doesn't give them credit for that. I also think both PMs and BAs identify and deal with business issues as well.
But regardless, industry is intent on driving a wedge between these two roles. I suspect that the reason for that is because there is more money to be made in training and certifications if these are considered different roles. But I really think PMs need to be strong BAs in order to be really successful. You can't just control the levers of scope, schedule, risk, cost, quality and satisfaction and expect to be successful. You need (at least for IT project management) to understand the underlying business process that is to be automated. You must see the big picture and you must be able to zoom into portions of it to see greater detail. You can't just implement a quality control system and then sit back and forget it. You must be a part of the automation process to know that stakeholders are in fact testing and verifying the deliverables.
Anyway, for what it's worth, to people who are serious about project success and mission success, these are not different roles. I might have someone on the project whose responsibility is primarily geared towards business analysis, that isn't a problem, but I am also a BA on the project.
