This kind of generic armchair general "advice"[1] is everywhere when you run a company and is basically completely useless because every company is a complex and unique special case and if you're in charge you don't have to make the decision that would on average be the right decision for companies of your type, you have to make the best decision you can for your specific situation. This goes double for people decisions because they have a huge impact on those affected so it behooves you to take the time to really do your utmost to do it right.
