I work at Google and generally love it but this is currently my #1 complaint about being on an infra team. We have no PM so it falls to me to figure out how best to apply the systems and tools we have in new domains... but I can't actually make these decisions unilaterally. It requires people on the other side of whatever engagement and those relationships are complex and often fickle and it takes a huge amount of my time to navigate them. We temporarily had a PM who got a bunch of initiatives started but then swapped teams and all of the momentum vanished.
