Re: UML and Scrum
- You're right, as usual. I think I need a Nikon D3x, so I can take 24.5 megapixel picture of the whiteboards. :-)
Continuous improvement is one of the key tenants of agile, and what could be a better improvement than going from 2 megapixels to 24.5 megapixels? Why, that's over an order of magnitude improvement! :-)

- I get lots of mileage out of banging out a bunch of class and sequence
diagrams using togethersoft and generating some code, taking screen
shots of the diagrams for quick and dirty future reference, than
focusing on the code,...
It accelerates the coding I do, mostly because I am a visual person.
I'm not as big a fan of visio because it feels like I'm doing it
twice, once in visio and once in the IDE, seems wasteful.
I take the hit for whiteboarding and sticky notes because its so
collabvorative, also think CRC cards are a great replacement for UML
and am a big fan.
