Working with your collaborators before and during your projects can be difficult, and each contributor may be using different methods and tools. COS develops and maintains the Open Science Framework (OSF), an open source project management tool that supports researchers throughout their entire project lifecycle. As a collaboration tool, OSF helps research teams work on projects privately or make the entire project publicly accessible for broad dissemination. As a workflow system, OSF enables connections to the many scientific tools researchers already use, streamlining their process and increasing efficiency. As a lifecycle facilitation tool, OSF has built-in workflows for pre-analysis planning and documentation, preprint publishing, and enhanced version control for tracking changes and contributions. Hands-on activities demonstrate how the OSF can support researchers in all of their project and reporting guideline needs.
