Question about MS Teams and Sharepoint sites [confusion]

towfiqi Like so many of our new tools, it is quite confusing because you can use almost any of them for anything.  It depends upon your use case.  But, here are just a few comments and things I've found...

We have a corporate intranet so our organization sites, which in most cases are information sites, so we use SharePoint sites. The navigation helps us present  and navigate through our organizational structure that is available to everyone in our company.   It allows us to present a unified and  organizational theme. 

Teams are generally used for smaller and short term projects; though they can be used for large and longer term projects.  

Teams is very limited as far as permissions go.  A standalone SharePoint site offers more options. 

You can spin up a team almost instantly, while building a site may take more time. 

It may be a silly correlation, but I sometimes think of them as the difference between dress clothes and work clothes -- if presentation doesn't matter all that much and you just want to get the work done; use teams.  If you want something more professional and longer standing -- go with a stand alone SharePoint site.   

I'm sure there are more, but those come immediately to mind. 

Again and seriously -- lots of gray area.  Good luck.  In time you'll figure out how the differences apply to your and/or your organization.
