For the most part, "career matrixes", "development plans", and the like are just generic internal marketing to placate people and create the illusion that managers / the company care about their career development, and they don't have to do anything.

To a lesser extent performance reviews / ratings are the same - "you're doing great, keep it up!" - they don't really tell you what you need to do to progress. You have to figure that out and drive it for yourself.
