5 Data Patterns That Scream 'Your Developer Is Burning Out'
Nobody quits on a Monday. The resignation email you receive on a random Thursday was written — emotionally — six weeks ago. The disengagement started three months ago. And the data saw it coming the entire time.
The 2023 Stack Overflow Developer Survey found that over 70% of developers reported some level of burnout symptoms. Replacing a mid-level software engineer costs an estimated 50-200% of their annual salary when you factor in recruiting, onboarding, and lost institutional knowledge. The SPACE framework (Forsgren et al., 2021) explicitly includes "Satisfaction and well-being" as a core productivity dimension — recognizing that burned-out developers aren't just unhappy, they're materially less productive. But the signals are visible in activity data long before the resignation letter.
Here are five patterns that show up in IDE activity data weeks — sometimes months — before a developer burns out or leaves.
