Guy/Adrian, thanks so much for your feedback, I was leaning towards Business Analyst Solutions, so it's great to hear some feedback from someone who actually provided courses there!

As you mention the ISEB Diploma in Business Analysis rarely features as a 'Must Have', but in the current climate and when there is such a high multiplier on Applicants to Jobs, having a qualification can help provide that extra edge needed to secure an interview.  From there on in however I suspect the course won't make much difference, but formalizing what I've self-taught and getting a chance to learn from people with a lot experience can never be a bad thing!

Thanks again!

Rob
