Slack is a new layer of the business technology stack that brings together people, applications, and data. It is a single place where people can effectively work together, access hundreds of thousands of critical applications and services, and find important information to do their best work. Slack has very general and broad applicability. It is not aimed at any one specific purpose, but at nearly anything that people do together at work. Slack is used to review job candidates, coordinate election coverage, diagnose network problems, negotiate budgets, plan marketing campaigns, approve menus, and organize disaster response teams, along with countless other tasks. lack provides an easy way for users to share and aggregate information from other software, take action on notifications, and advance workflows in a multitude of third-party applications, over 1,500 of which are listed in the Slack App Directory. Further, Slack’s platform capabilities extend beyond integrations with third-party applications and allow for easy integrations with an organization’s internally-developed software.
