Slack helps us keep the conversation focused and avoid multiple threads that create more confusion. I would say that has been the biggest advantage for us.
Slack enhances productivity by integrating with apps and features like video conferencing and document exchange while ensuring focused team communication with threaded discussions and channels. Customization options, message deletion, and alerts add versatility. However, there are challenges with mobile notifications, app stability, initial setup, and integration with tools like SharePoint. Limited document preview and cumbersome channel management are concerns. Improvement is needed in these areas for optimal performance.
