Why Do We Use Slack?

Why do we use Slack?

As mentioned above, Slack is one of the best team collaboration tools available for enhancing and maintaining internal communications between individuals and teams. Slack is considered the best for remote teams wherein the users can not just easily share their screens but also stay connected to the team by logging on to any device (phone, tablet, computer, etc.). Here are some of the top reasons why we use Slack:

– Create channels for specific projects, events, etc., and add only relevant people to them. This ensures that the communication is streamlined, and everybody involved is aware of what is happening.

– Avoid diving into your folders and sub-folders to search for documents and files. Simply attach your files to the respective channel and access them whenever you need them.

– Avoid multiple back-and-forth emails. Having discussions on Slack allows you to search for them in the future whenever required. 

– Rather than just a communication tool, Slack can also be used as a complete project management tool, thanks to its various plug-ins and integrations.
