Big Batches™ and assumptions

Big Batches™ embed:

• more assumptions
• way more second-order, compounded assumptions as a product of first order-assumptions (A x B x C x … x N)
• carry all of these for a longer time

Small Batches™ embed:

• less assumptions
• less second-order assumptions
• carry all of these for a shorter time

Which one of these is likely to have more waste compared to the amount of effort invested?
Or, to rephrase it, which one of these has a higher effort/value ratio?

Lose-lose-lose vs win-win-win if you ask me.
