Threaded collaboration has transformed how our team tracks tickets and monitors automation updates
One suggestion I would make for improving Slack Business - Enterprise is the support of multimedia such as images and videos that we can easily share through Slack. That would be great. Additionally, another thing is AI integration; if Slack has some AI capabilities to get insights about conversations or summarization, that would be a great feature. If Slack has an AI feature that can summarize a particular Slack thread and provide a summary of that, that would be a great feature for us. I would rate it a ten if it comes with some AI features, particularly using generative AI to produce summarization and other kinds of insights from communication in a more secure, data-secure way.

I think we should have some improvements in Yammer, similar to what we have in Facebook and others, where we can have targeted communications, so that we can filter some communications to go to a specific subset of that group, not to everybody. We would love to have some AI technologies included in Yammer, but I do not have a specific use case in mind right now.

Quotes from Members

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

Pros

"One thing I like about Slack is the ability to change the color of Slack. It depends on my mood. When I'm having a bright day, I just change the background color of my Slack, which is nice."
"Communication with clients became easy."
"If you're looking for an asynchronous/real-time communications tool, you will not find any app that comes close to Slack."
"Slack is a very robust, flexible platform, which allows for a lot more, not just chat."
"Slack has been very useful in our organization for doing communications and passing on pieces of information."
"The product is easy to use."
"Slack makes it easy for employees to contact each other and exchange documents or information."
"Process made easy Collaboration between teams increased Productivity is now largely increased: top."
"The most valuable aspect of the solution is that anyone can post anything, it's free and people can do it on their own without having to translate to publish, and it's really easy to use."
"The most valuable feature of Yammer is its interface."
"The integration with Teams is the biggest value for us. In fact, it has only become more valuable now that it has integration with Teams. Teams allows you to stream, so that's good."
"It is good, it works, it is reasonably easy to use."
"Yammer is useful since it is a product you can easily integrate into our system since Microsoft supports it."
"Messaging and groups are the most valuable features."
"People share their files and ideas and attend meetings in a collaborative manner."
"My organization invested a significant amount of money in the Office 365 package, and Yammer is a must if you plan to work on improving the internal communication and collaboration among your staff."
 

Cons

"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."
"Slack feels clustered and hence it should improve its design and UI."
"The only area of concern that I have is with the inability to preview received documents without having to download them first."
"Sometimes there are login issues."
"I would like the text in chat to be more customizable."
"Slack is not as strong as competitors like Teams when it comes to things like video meetings and audio meetings."
"The tool has stability issues that need to be improved. We are not native English speakers and Slack needs to integrate grammar checks."
"Slack does not have videoconferencing capabilities, which would have been nice."
"We tried to integrate into SharePoint, but it was not really efficient."
"I think that improvements could be seen in the delayed messaging, but other than, it's great!"
"If you are not an Office 365 shop, then there are probably better options (i.e., Slack, Facebook for Work)."
"The ability to edit posts can be frustrating for some."
"If you are using other applications that are tough to integrate into the environment, that can cause limitations."
"I'll give it a six out of ten because I'm comparing it to what's out there."
"I would give the technical support a rating of 3/10."
"There needs to be access to a channel, without the need to sign-in."
 

Pricing and Cost Advice

"It is less expensive than one of its competitors."
"I would rate the tool's pricing a four out of ten."
"The solution’s pricing is cheap."
"We use the free version that does not have a license."
"The solution is expensive."
"It is an affordable solution."
"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."
"The tool's pricing could be cheaper."
"Yammer is a pretty cheap solution, and it's included in multiple subscriptions."
"The pricing is not bad."
"I don't know about the pricing. Now that Microsoft has bought Yammer, it should be a part of our subscriptions for Office 365."
"I think that there is a need to make yearly payments towards the licensing costs of the solution."
"Its cost is included in the license bundle for Microsoft."
"Compared to other products like Amazon, Yammer's pricing is fine."
"We get it as part of our Office 365 subscriptions, so I don't think we pay any additional cost for Yammer. It's included in the Office 365 subscriptions."
