ROM Estimation training website

Rough order-of-magnitude (ROM) estimates are a long-standing way to get a feel for how big your project or program will be.  Nothing too precise of course, but that’s to be expected. 

Speaking for myself, I haven’t paid too much attention to practicing this technique.  To remedy that, I’ve been doing some visual training that you all might find useful as you prep for your next wild-ass guess ROM.  

See how good you are at “eyeballing” here.
