Featured Reviews

Akhil Viswam - PeerSpot reviewer
Senior Consultant at a consultancy with 10,001+ employees
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.

Creates user groups and streamlines communication
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

"The integration with third-party automation services such as IFTTT and Zapier has significantly boosted productivity."
"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."
"The feature that I have found most valuable is communication between team members."
"It is easy to set up."
"Slack is a powerpack bundle of features that help small or large organizations to handle teams and their tasks."
"The product gives the best user experience."
"We use thread-based communication. So that if a new person comes to look into a problem for a particular task, they can easily go and look into the particular thread it is discussed in."
"Communication with clients became easy."
"It's really easy to use the solution."
"Yammer's group page functionality is useful for large groups to collaborate instantaneously."
"It was reasonably good at creating online communities of interest."
"Increased collaboration between geographically distributed teams."
"Integration into SharePoint is a valuable feature as it provides better exposure and access to users."
"Yammer allows collaboration anywhere, anytime, on any device."
"From the point of view of knowledge sharing, we created a group per project, and while we had SharePoint for storing documentation, we were able to link to these and give them content in Yammer."
"I have found it to be a good tool for building communities and for improving communication."
 

Cons

"The tool is a bit slow."
"The only area of concern that I have is with the inability to preview received documents without having to download them first."
"Slack's channel and chat management could be more intuitive. Configuring chats and pinning in Teams is easier, even though Slack has these features, they are not intuitive enough to engage with."
"I believe they can improve upon ‘calling’, which was introduced recently."
"The UI could be a little bit better."
"I want a feature in the solution that will help me share documents only with the set of people that I prefer rather than all of them. I would also like the solution to have a feature similar to Microsoft SharePoint where you can group all your documents."
"The solution should have less frequent updates."
"Notifications are not as good as they could be (especially for mobile)."
"Although Microsoft is working on it, having a centralized network instead of creating multiple networks based on a domain would help businesses with multiple companies or child companies."
"However, it was mostly slow, clunky, and frustrating to use."
"I think that improvements could be seen in the delayed messaging, but other than, it's great!"
"Yammer is not as feature rich as the most mature offering in this space, Jive, however it makes up for this with strikingly intuitive ease of use and a much lower cost."
"Microsoft should work on templating and provide some built-in templates so that the changes can automatically roll out to all the configured communities."
"Technical support specifically gets a fair rating."
"There is room for improvement in the customization and administration aspects of the product."
"Navigation to different Yammer Groups could be improved."
 

Pricing and Cost Advice

"The solution is cheap in my country."
"The solution’s pricing is cheap."
"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."
"I would rate the tool's pricing a four out of ten."
"The solution is expensive."
"It is an expensive tool. We pay 15 to 20 USD monthly per user."
"We use the free version that does not have a license."
"The tool's pricing could be cheaper."
"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."
"I don't know about the pricing. Now that Microsoft has bought Yammer, it should be a part of our subscriptions for Office 365."
"Its cost is included in the license bundle for Microsoft."
"Yammer is a pretty cheap solution, and it's included in multiple subscriptions."
"I think that there is a need to make yearly payments towards the licensing costs of the solution."
"The pricing is not bad."
"Compared to other products like Amazon, Yammer's pricing is fine."
