Wardley mapping
Everything you depend on is moving from novel to commodity, at different speeds.

Simon Wardley's mapping places a value chain against an evolution axis running from genesis, through custom-built, to product, to commodity and utility. Position on that axis should dictate treatment: build the novel, buy the commodity, and never the reverse. Wardley published the method openly under Creative Commons, which is part of why it spread.
Sourcing mistakes in AI are almost always position mistakes. Organizations lovingly build what has become a utility and procure what is still genesis, then wonder why neither worked.
Where on the evolution curve does each capability sit, and does that dictate build, buy, or let go?
What is owned, what is rented, and what is summoned only when needed?
