docker and Makefiles as task runners. I have a git repo that is the skeleton for this idea: https://github.com/undernewmanagement/flight-deck

On mac we have homebrew to pull in all the desktop apps and cli tools. Then a simple bash script to automate all of it.

I've managed to "retrofit" this into a team of 20+ devs and product owners for a variety of services.

We are even piloting this with sales and support so that they can stay abreast of bleeding-edge development and provide valuable feedback.
