What is Sparx and for what purposes it should be used

[Glassboy]

Like I said before the learning curve is massive for both Enterprise Architecture Discipline and the Sparx EA tool so you really need to bring in some experts. My colleagues call me an expert but I still sometimes struggle with some aspects from time to time and I've been using Sparx EA for Enterprise Architecture over a decade now.

I ran into someone on the street the other day who said something along the lines of it's really only the pair of us in town who have a decent grasp on modelling an enterprise using tools like EA.  So you can probably have expert, but "dedicated" is probably closer to your reputation.  :-)
