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 is a really easy collaboration tool to use and many companies are adopting this popular tool."
"Its intuitive design makes it easy to use and understand, hence we do not have a need to spend much on educating our teams."
"I use Slack for communication with my colleagues."
"The most valuable feature is that we can easily integrate different workloads and the alerts are reliable. Also because it allows us to use it as a monitoring tool sometimes."
"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."
"Tasks and team huddles are the most valuable features of Slack."
"Slack offers several valuable features. Firstly, they have a message deletion feature, which is now available in other software as well, but Slack was the one who introduced it in enterprise solutions."
"The huddle feature is valuable to me."
 

Cons

"The audio calling service needs to improve its quality."
"There were some additional features coming up, as they informed us through email. But we didn't get any update on them."
"I would like to see a special feature for multiple people to collaborate on a document, working on it at the same time."
"It is difficult to navigate the tool when I log in to two devices and start a video call."
"The mobile app needs improvement. It consistently misses notifications."
"The integration with SharePoint doesn’t work properly."
"The solution needs to improve its scalability."
"It would be better if Slack had a 'select all' option to delete all the files."
"It would be highly advantageous if it could incorporate calendar information from sources like Outlook or Gmail, providing users not only with meeting schedules but also a comprehensive daily agenda view."
"Slack's screen sharing might also add the remote control feature, which is not there."
 

Pricing and Cost Advice

"The license grants you a subscription and costs about $120. I am not aware of additional costs."
"Slack is not the cheapest solution, but that's okay."
"The pricing can range up to about twenty bucks a user. You can spend a lot of money, especially if you're talking about thousands of users. Generally speaking, Slack is less expensive than Teams. Slack doesn't include all the bells and whistles that Teams does. So you can go from a $6 license in Microsoft 365 to a $50 license per user per month, and there's a lot more you can do in the $50 license."
"Slack is definitely worth the money."
"The solution’s pricing is cheap."
"I would rate the tool's pricing a four out of ten."
"We use the free version that does not have a license."
"It's on the more expensive side."
"It is an affordable solution."
