I don&#x27;t have any book recommendations but it really is just management skills, so look up some business books.<p>The main temptation you need to avoid is &quot;micro managing&quot;, and instead you just need to have faith that people will do what you ask them to do, albeit via a different path than you may have taken.<p>In terms of justifying the cost of labour versus DIY - it&#x27;s just an &quot;opportunity cost&quot; argument. If you can get better returns from your time by doing something else (eg not programming, and just dedicating a bit of time for coaching your people) then it will be worth employing others. If not, then stick with what you are doing.<p>Hope that helps :)
