Conversations by topic
A Slack channel is a shared conversation for a team, project, or topic. A thread keeps replies to one message together. Direct messages let selected people talk outside a channel; a huddle is a quick voice or video call. People can use Slack in a browser or an app on a computer or phone. Microsoft Teams offers similar workplace chat and meetings.
During an incident, a team might use a channel to share updates and coordinate. Other tools can post alerts there automatically. Who can read a message depends on the workspace and channel settings.
Keep important decisions easy to find
Decisions can get buried in long conversations. Teams record lasting guidance in a shared document or runbook and link to it from the channel.
