My bad if I gave you the wrong impression about management types. You're right that things should work. What I meant was this: assume you have technology stack A and B each with its own pros and cons (whether tech maturity, programmer skills or what have you). Then, higher management expects the lead programmer/engineering manager to review the pros and cons and take the decision and deliver keeping the end user in mind. Whether stack A has xyz features which will do blah-blah-blah to the team is less relevant than the deliverable. Hope it is clear :-)
