Tools for Enterprise Architects: OmniGraffle for iPad?
By Pat Shepherd on May 14, 2010
Well, I have to admit to being a bit of an Apple fan and, of course, and early adopter of gadgets and technology in general. So, when FedEx showed up with my iPad 3G last week, I was a kid in a candy store. One of the apps that my “buy finger” was hovering over for a while (like all of 3 days) was Omnigraffle for the iPad.
I imagined that it would be very cool to use this with a customer’s EA’s to sketch out Business, Application, Information and Technology architectures. Instead of using the blackboard, this seemed to offer promise as a white-boarding tool with obvious benefits over a traditional white-board. I figured I’d get a VGA adapter, plug it into the customer’s projector and off we would go with a great JAD tool. The touch pad approach offered an additional hands-on kind of feel.
So, I made the $49.99 purchase + the $29.99 VGA adapter and tried to give it a go. Well, I was both pleasantly and unpleasantly surprised. It is both powerful and easy to use. There are great stencils included for shapes, software icons, Visio shapes, and even UML notation. There is even a free-hand tool that works well. I created some diagrams pretty quickly. The one below was just a test and took all of 10 minuets to do.
The only problem was that Onmigraffle does not recognize the VGA output, so I was stopped dead in my tracks, as it were. My use case was as a collaborative diagramming tool with other architects, though I can still use it off line. I called Omnigraffle and they said that VGA support is on the feature request list so, hopefully, in a short amount of time, I can use the tool as I envisioned.
NEW UPDATE: A question I got from Todd Biske “…was whether the touch interface has sufficient resolution. I've tried some basic sketching with Adobe Ideas, and I must admit, I find myself longing for a stylus. Can you comment on this?”
So, the answer is yes. You can use the 2-finger pinch motion to zoom in and out to well over 600%. At that resolution you can make all kinds of intricate connections and refinements. Hope that helps :-)
