A collaborative tool with a good noise cancellation feature
We use it to conduct meetings because it is private.  The microphone's noise cancellation and static feature that record a human's voice are some of the most valuable features. The application also provides notices to everyone at the same time. You can easily use it on your phone, so it's a very…

A competitive solution that improves collaboration and productivity
Slack has been around for a long time, and it's an industry leader. Of course, Salesforce owns Slack now and is starting to integrate into it. I have attended Slack conferences and met with product and support managers. They're an excellent organization. Choosing Slack depends on the organization's size, so you need to plan your deployment and make sure you put some controls and standards in place and not just turn it on. If you're a Slack shop, you will have to have something like a Zoom or Microsoft Teams platform for when you need to do video conferencing internally or externally. Many shops have both products, but they use Slack for collaboration, chat, and so on, and use Teams for video and audio conferences. At the end of the day, Slack is missing those capabilities, so either you're going to be a Slack/Zoom shop or you're going to be a Microsoft Teams shop. I rate Slack an eight out of ten.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The microphone's noise cancellation and static feature that record a human's voice are some of the most valuable features."
"We use the solution for document sharing, video conferencing, instant messaging, and file sharing."
"Slack makes it easy for employees to contact each other and exchange documents or information."
"Slack is a very stable product."
"Overall, it is a good idea as it works better than most solutions out there."
"The most valuable feature for me was the different channels."
"Slack helps me to read bulk messages."
"Slack is a collaboration tool where you can create specific topic-related channels and manage different threads on different talks so people can interact and maintain a chat."
"The product has the ability to scale."
"You can create channels between teams internally and externally, which is great. There is a lot of security with Slack internal, which is what I value."
 

Cons

"There were some additional features coming up, as they informed us through email. But we didn't get any update on them."
"The audio calling service needs to improve its quality."
"Slack tends to crash once a month."
"Slack feels clustered and hence it should improve its design and UI."
"The solution's user interface is not very good and changes very often."
"We could see improvement in Slack by having an integrated meeting tool. Currently, we rely on third-party integration tools like Zoom to schedule meetings. It would be much more convenient to schedule meetings directly within Slack without additional integrations. It needs to have calendar and CRM integrations as well."
"I have found it cumbersome to create and set up groups, or channels."
"Slack does not have videoconferencing capabilities, which would have been nice."
"It would be better if Slack had a 'select all' option to delete all the files."
"When someone responds to my message in Slack, a new window opens. There should be an option to roll down the answers."

"The tool's pricing could be cheaper."
"The solution’s pricing is cheap."
