What i would prefer, is to take a step back and look at all major interest partys involved, who will deform the development process. If management puts to much pressure on, a good process would give tech and the customer more chances to counter said pressure, to avoid tech debt and badly implemented features.

I want a process that reacts to the situation, in favour of the product, in favour of longterm goals - who actively resists people who try to gamble it for whatever reason. Agile is not that.
