If you are a G Suite customer, you should also use Slack. Slack is much more powerful and user friendly than Google+ or Hangouts Chat. The combination is the best example of what I’ve called productivity/participation dimensions in my collaboration model on which CIX is based. G Suite, essentially Google Drive, Docs and Sites, are the archetypes of modern productivity tools, 100% web-based, natively collaborative, allowing real-time co-edition and advanced sharing capabilities. In the other side, Slack is the archetype of modern participation tools (or conversational tools), having transcended all previous generations as well in features than in design. Highest adoption rates are guaranteed.
