Build vs. buy vs. subscribe is the most consequential AI decision you'll make this year — and the easiest to make poorly. This Module 7 worksheet forces a structured comparison across the seven factors that determine total cost over the long term.

What's inside

Time to value, upfront cost, ongoing cost, customization, expertise required, vendor dependency, and maintenance burden — scored across all three approaches. Built for the executive who needs to defend the choice to a board.

How to use it

  1. Print it or fill it digitally — don't try to do this in your head. The friction of writing is part of the value.
  2. Complete it with someone else who has different context. The disagreements are where the real insights surface.
  3. Date your worksheet. The point of a structured tool is to compare answers over time.
