PagerDuty has introduced a new on-call scheduling tool that provides users with extensive flexibility to create various on-call rotations, such as recurring schedules and "Follow the Sun" shifts, by utilizing a layered approach similar to digital image editing. This tool allows for diverse scheduling configurations, from daily developer rotations to unique weekly shifts, and has been positively received by users. The tool incorporates features like smooth responsive JavaScript, non-blocking page loads, and dynamic calendar previewing, contributing to an enhanced user experience. As part of a broader effort to modernize their application stack and interface, PagerDuty is leveraging Twitter’s Bootstrap Framework to facilitate intuitive navigation and productivity. iCal and Webcal integration have also been added, with more updates anticipated in the future.
