Slack
Sending messages, sharing files, and coordinating team communication in organised channels
Slack is a business messaging platform that organises team communication into channels — persistent, searchable threads grouped by project, topic, or team — replacing email as the primary internal communication method in many technology organisations. Users send direct messages, share files, post threaded replies, and receive notifications from connected tools such as GitHub, Jira, Datadog, and Salesforce directly in the relevant channel. Workflow Builder allows teams to automate simple multi-step processes without code. Slack's search function covers the entire message history and shared files, making it a de-facto record of team decisions, context, and discussion. It is the dominant business messaging tool in technology companies and is a standard workplace expectation across most tech roles.
