Witold Rybczynski makes an interesting comparison between military and civilian (city) planning in a recent blog post called, "The Fog of Life." Here's an excerpt:

Good military planning, as I understand it, is based on preparing for “what if,” that is, developing different scenarios. What if this happens, or that happens? City planning is different, more like advocacy, that is, what should happen. This advocacy is based on certainties: open space is good, density is good—or bad, depending. The problem is that what planners think should happen—separation of pedestrians and cars, superblocks, megastructures—often runs into trouble when it hits the fog of life.

These are two very different perspectives. "What if" planning responses assume that a thing has already happened. You're not working to affect a particular outcome, you're responding to one that already exists. Does this necessarily make this approach more reactive than proactive?

Either way, what should happen implies that the thing isn't currently happening, but that it should -- presumably because the thing is nice and desirable. It could also imply that the thing is sort of happening, but just isn't happening quite enough.

Let's use the example of 3-bedroom condominiums and apartments, which is a topic of discussion that has been circling in Toronto for as long as I've been in the business. Developers here, are generally encouraged or mandated to build a certain number of larger family-sized suites in every new housing project. Oftentimes this number is 10% of the total unit count.
