Some things are particularly difficult.
1. Communicating effectively and efficiently across multiple personalities, teams, and departments is difficult.
2. Solidifying job descriptions, career paths, incentivization structures, and hiring processes is difficult.
3. Moving forward as an entire company with a cohesive business strategy is difficult.
4. Ensuring managers are qualified and supported is difficult too.
You know what's even more difficult? Not putting in the time to address these challenges and hiring more people instead.
Poor communication is amplified. Resentment around career opportunities grows. Chaotic, rogue business strategies run rampant. More managers get overwhelmed and more direct reports are misled.
If you're a growing company, consider the benefit of another body and weigh it carefully against the cost of scaling any unresolved problems you need to address. It might be worth the wait.
