Well, whenever I'm confronted by some kind of management thing like this I try to think about it from the manager's perspective. First, it seems like this is something that matters when a "10-point bump on engagement scores" is how your manager is being rewarded. Also, they don't necessarily know what you're doing all day but they can sense you don't really care that much about it. That makes management nervous, because they DO know turnover is bad. So, at a company where the engineers don't actually really care that much about what they're working on they want to try and manufacture that environment. So you create a "career plan" for someone to keep them engaged for the next 6 months to build the widgets you need.

I do find it interesting that one of the quotes in the article is "They discover that in three to five years, a bunch of people are going to leave because they're concerned about career growth and development. Panic ensues". Uh what? Three to five years is a pretty good stretch these days in SV. If you really wanted to keep people longer than that, you would have a completely different business and reward structure.

The rest of it boils down to "get to know your co-workers", I guess? It doesn't really seem that revolutionary. If you want to spend more than 5 years working with them, I think that should happen naturally not as part of some kind of corporate management mandated dream sharing time.
