A lot of assumptions that I think distract from the important - understanding the need vs solution first thinking.<p>The business might not be out to build their slack, chat could just be enough of a transformer alone.  Besides, Slack is IRC client re-skinned with a bit different rendering.  It&#x27;s not the first either but maybe a business case is good enough to just chat as a big improvement.<p>Many organizations do just fine using something like Microsoft Lync, as much as I like Slack it&#x27;s not for all users or instances.
