Do you get overwhelmed by all the diff places you have not work out of with your team? i.e slack, GitHub, Jira, etc??
Define small.
I manage a 3-man company (including me) and I would say that in this environment unused tools died out very quickly.
I think I tried dozens times to push Azure DevOps with kanban process to the team, but that just does not work for us.
And after all, only essentials tools left - for us it was telegram, notepad, devops repos, devops ci.
