I’ve seen it firsthand. Teams that thrive with STACK have one thing in common: someone who owns it from start to finish. The number one reason implementations stall isn’t the software, it’s that the champion leaves and no one picks up the torch. Every successful team needs that internal STACK guru — the person who knows the platform inside and out, trains new estimators, enforces standards, and becomes the go-to resource when questions come up. Without someone driving adoption, enforcing estimating standards, and keeping the process alive, even the best rollout reverts to old habits.
