Work at grifting, yes -- but the description associated with that quadrant is someone who actually works for the goals of the organisation: this is the literal opposite of grifting.
Like, the post says "You want a grifter leading a complicated engineering project".
Believers are too inflexible and will kill the project eventually because of it.
Coasters won’t work enough to deliver the project.
Grinders will eventually burn out and devolve into coasters, or start divert the project into unrelated territory (focusing too much on optimization, testing, accessibility).
Grifters are the only ones who can lead projects, because they understand where the wind blows.
Yeah. And I'll just add, so often the success of a project is not in its technicals, but the smoke and mirrors that are used to sell it. Be that to upper management, clients, regulators...
Right. But if you do all of that in service of the collective goals of the project, you are, by definition, not a grifter -- unless the project is itself grift.
