I work at an agency that started out building websites and small apps, but the past years have shifted towards larger web apps and products.

Small projects are easy to manage. GitHub issues or Basecamp todos are more than enough to keep things going. Adding a feature or refactoring a small project is also easy, because there aren't too many moving parts to take consider.

Large and especially long-living projects are constant moving targets. It's harder to estimate things and technical debt can become a real issue. A linear, chronological task list won't do it anymore, we need to start prioritizing things.

I want to share four systems that have helped me, both on a personal and team level, prioritize work on large projects.
