Here’s a bunch of tools, articles and education tools that I use on the daily.
Articles & Thought Leadership
Wes Jones: Producer Playbook (this is an AWESOME resource for agency Producers).
Code as Craft: Blameless PostMortems and a Just Culture (7 years old and still amazingly relevant)
Education & Recruitment Tools
New or looking to get in to project management? The Art & Science of Leading Projects by TeamGantt is a good place to start.
