All that "determines a vision and strategy" means is "deciding what the company should do next". Which isn't really nebulous at all, and its impact on the organization can be directly measured by success/failure. E.g. Ben Horowitz "determined the vision and strategy" for Loudcloud when they moved away from managed services market and spun out Opsware, which led to a 1.6Bn exit.
