While there are many ways that projects can define and measure health, this talk will focus on maintainers as they are critical to the development, leadership and governance of their projects. As burnout continues to be a growing issue across roles, industries and communities, losing maintainers within small communities can have detrimental impact on the sustainability of that project. This talk will discuss methods and metrics to identify signals for overloaded and overworked maintainers. While metrics alone cannot fix the problem, they can help to proactively flag emerging issues so your community can adjust before it's too late.
