Collaboration is a “Mindset”, not a tool.
However, in order to deploy a collaborative mindset to your career as a leader or to your organizations operating characteristics, tools are usually helpful.
We are providing links to a list of articles, blogs, and advertisements for what others call Collaboration Tools so that you can evaluate their usefulness to your needs. Let us know if you have others to add to the list, we appreciate the help!
