I use Slack primarily for communications. This includes communicating with individuals as well as grouping people into cells to work on specific parts of a project. We don't use the features beyond just the basic communicative side of it.

We use it for internal communication, and we also use it for external communication or customer relations.

Our internal team primarily used Slack for communication with each other. If two or three people were working on the same modules then they were able to share code and work together.

We used Slack for all of our internal communications during the COVID pandemic.

We use Slack for general communication, conference calls, and sharing screens because we have people working from different countries.

There are 53 people using Slack in our organization.

The solution is deployed on-premises.

The solution is deployed on-premises. We have around 65 people using this solution in our company.
