I worked at FB for a while, and the problem with long term projects were that they were long term. In FB you need twice a year to make self review that shows what kind of impact you created during last 6 months (and based on this you are rated, raises, refreshers, etc). In long term projects impact might be only at the end of project, which leaves you "impactless" for a long-long time. Because of this people didn't really want to join any long term projects. While I was there management was trying to resolve this situation and transmit message that long term projects are impactfull and important (and strategic to company), yet they couldn't answer question of how impact should be calculated every 6 months. Maybe by now they came up with some formula or something
