PM Engineering Partnership
(2026 Edition)
Good PM-engineering partnerships bring problems instead of specs, estimate in ranges rather than fixed dates, and protect focus time instead of stacking meetings — with the TL owning technical implementation and the PM owning product outcomes, deciding together only where the two intersect, like architecture that shifts time-to-market.

FAQ
Who owns technical decisions — PM or TL?
