You work at thoughtbot. This is your playbook. It details how you and your teammates run our software consulting company and how we make web and mobile products together. It is a living document that you can edit in a private GitHub repo.
It's filled with things we've learned based on our own experience and study of others' experiences.
We've made the playbook free and licensed it as Creative Commons Attribution-NonCommercial so others may learn from, or use, our tactics in their own companies. While our "plays" have worked for us, we trust their judgment over ours to decide which tools and techniques might work for them, too.
