As the name suggests, roadmaps should have the properties of a map (What are the properties of maps?) Maps are multi-scale, Maps help you understand the state of something, Maps help you figure out possibilities and explicitly point out those possibilities and associated tradeoffs.
Most roadmaps do a poor job on many of these points. Instead, they feel like a mush of keywords and key phrases that someone evaluating a grant could check against and say “aha! This grant is legitimate because they’re trying to do this this thing that’s mentioned in the roadmap.”
Of course, it’s possible that creating a good roadmap is an impossible task. It may be impossible to create a roadmap that actually enables coordination and progress that would not happen otherwise. However, the assertion that most roadmaps suck is based on a list of points that are very possible to fix.
