As an experienced Business Analyst I have had opportunities focused on very specific roles within a very specific Banking domain. I have not had opprtunities to be a Data analyst or a Business Intelligence BA as my primary roles. I have had more of functional business analysis roles with trading systems.

As I look to progress, I see a PMP certification as a natural progression, however that does not motivate me much. I am interested in Big Data and wish to explore suitable skills I can acquire but I do not wish to deviate my core functional Business Analysis skill set. In other words I do not wish to become a Hadoop developer or a Data Scientist.

What are the appropriate avenues for a BA and what combination of skills one should seek to be considered as a business focussed Business Analyst with Big Data?

Are there any certifications available that existing Business Analysts can leverage to present appropriate Big Data skills?
