We have an IT team to take care of the deployment. There was no maintenance required. Whenever there were situations where Slack was down, we were informed. So there was nothing else except for updating the client version whenever a new update was released. But that's the extent of the maintenance. It was limited to that. It was more like an app update. Since it was on the cloud, there was nothing else for us to update. Whenever a new update was available, Slack would send us a message, and we simply updated it.

The vendor handled our implementation and did a professional job.

We deployed this solution ourselves. It was easy to send employees invitations to join.

Through an in-house one. Level of expertise was as great as it could get.

It was an in-house implementation and easy to set up.

Neither, as it came pre-installed.

In-house.
