Momentum is the rocket fuel, the turbo boosters, the engine that ships and ships often. Momentum feeds itself from every shipment, every deliverable sparks the flywheel with satisfaction, confidence and education. Why then would you create big lists of deliverables for each shipment? Why would you pile on and delay a shipment? Why limit the moments to grab momentum to few and far between?
Don't. Reduce and refine. Ship smaller deliverables. Ship them often. Celebrate, test and recalibrate, and do it again.
