I was a Team Lead over the years. My biggest difficulty was non-support from my manager, directors, and VPs. We were stuck using tools that didn't work, and there was no funding to fix them or get better ones. Processes were stupidly designed, and nobody wanted to improve them. Great ideas are all shot down. Even cheap ideas are shot down. But we can cut thousands of jobs, fund a Mclaren race team, get g2 a $200k watch, etc.
