Introduction

In the early hours of the morning as you are sleeping in bed, your phone starts to ring. It's not the normal ring that you've set for friends and family but the red-alert ring you set for emergencies. As you are startled awake by the noise, you begin to come to your senses. You think of the recent release of your company's application. A sense of dread fills you as you pick up the call to be greeted by the automated voice on the other end, informing you that you've been requested to join a priority video conference with a team debugging a live site problem with the new release. You get out of bed quickly and join the call.
