I have a first degree equivalent in Accounting, a PGD (Management) and I’m currently studying for an MBA.
I registered for ICAN some four years ago but only attempted the exam once.
I have done some studies on Project management and Lean and six sigma with some private institutions but haven’t gone for certification.
I however intend doing CISA (Certified Information Systems Auditor) this year.
What do you think?
Have I missed my career path?
Do you see me doing well in another industry’s Operations or Supply and distribution department etc?

Your career aspirations from what i can see can be described as scatter-shot.

Why don't you try these:

What were you doing during your 8 years in Oil and gas? Your answer here is important for your future decision.

Is it something you like and would want to continue in?

If no, choose two compatibles (your likes) from the list of unfinished certifications you have put forward and go on from there.
