Online collaboration in the workplace allows for scalable participation beyond physical constraints, bridging distances within and outside an organization. It differs from external social media in that it challenges but extends established company structures and hierarchies while maintaining business processes and virtual "walls". To build online communities and scale collaboration, organizations should establish a shared vision to guide active contribution towards shared goals and outcomes, maintain coherence as new participants introduce dissonance, and start small while focusing on meaningful interactions and purpose. Online collaboration can be supported through technologies that reflect strategic habits, continuous experimentation and iterative prototyping of new and existing tools, and explicit sharing of captured learnings.
