At Zapier, they practice "support-driven development" where everyone contributes to support, and a solution was developed to help teammates know their upcoming shifts. To achieve this, they use Google Calendar, Twilio, and Zapier. The process starts with setting up a new calendar in Google Calendar for the support schedule, making sure each event is recurring with no end date. Next, signing up for a Twilio account and saving the Account SID and Auth Token are required. Finally, using Zapier to connect Google Calendar to Twilio and set up a zap that sends an SMS 15 minutes before each shift begins. This solution can be applied to any team with on-call systems for monitoring essential systems.
