Model: 3x for estimates
“No estimates” idea is great or bad depending on which phase you’re in
explore: estimates are waste -> great idea in exploration, because you’ve never done it before -> estimate is just a guess, no value, wasted effor
expand: (not mentioned in talk)
extraction: -> estimates are important data for making decisions -> do I do project A or project B -> estimates are useful input for ROI
