IBM Connections can help revolutionize project management by providing a single source of truth for all project information and enabling teams to connect, communicate, coordinate, and collaborate more effectively from inside and outside the collaboration tool. It allows teams to manage project components, track work through version control, easily share and discuss information, and capture related communications and documents. Extending Connections through APIs and widgets provides additional functionality for activities like notifying teams, embedding experiences, and reading/updating data to bridge systems together.
