We had a course as undergraduates around information technology projects in workplaces. I don't quite remember the brief for the final project that we were to put together. But the problem we ended up exploring was partnerships across department and many times organization lines.
My general thesis was that to transparency social ways to communicate on a digital platform that wasn't as rigid as email could have hugely positive implications on workplace efficiency. There was no Yammer, Facebook Workplace, Google Workspace, or Slack at this time. Email was king, but we had general social media to get inspired from. As a part of the final project, as a team, we outlined what such a social platform could look like and what challenges would need to be overcome in making it work. It was very much what Yammer became.
