This is a simple mantra I’ve used in many teams I worked in or led over the years:
Prefer Services to Software
Make services that are robust and functional.
Buy services that other folk do better than we could for the time and/or money.
Prefer Software to People
Automate everything where possible.
Output actionable telemetry for all the things.
Prefer People to Bureaucracy
Trust in the people you’ve employed to do the right thing and do it well. Remove unnecessary paperwork and processes whenever you can.
Prefer ChatOps for Everything
Email is so 1990’s. Put everything on Slack so everyone can see it.
Make command and control of your systems intuitive, accessible and secure.
