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 solution makes it easy to create groups, share documents, and communicate."
"I am impressed with the product's calls and screen share features which are very useful."
"Overall, this is a good product and I can recommend it."
"I like Slack's notifications. It is more user-friendly and pleasing than Teams."
"The custom integration or bespoke integration through Slack APIs is the primary reason that we are still on Slack Business - Enterprise and we have never thought of migrating to any other vendors or exploring any other vendor."
"Slack Business - Enterprise has impacted my organization positively by making communication easier between different departments."
"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 most valuable features are video conferencing and sharing content during meetings."
"Yammer has allowed the entire company to be able to communicate with each other when the company has internal employees from all over the world."
"There are so many features, everything you could ever want, which is great for team collaboration."
"The most valuable feature of this solution is the communication events."
"Yammer provides a simple to use, intuitive platform for enterprise collaboration within the social networking information model."
"Groups is the most valuable feature in Yammer."
"The user interface and the way we can share and search information are the most valuable, and it is very easy to use."
"This product is very easy to use, and has been widely and easily adopted."
"We have set Yammer up inside IFrames that appear on our intranet home page, most content pages, and in all-team sites."
 

Cons

"Slack is not as strong as competitors like Teams when it comes to things like video meetings and audio meetings."
"Microsoft and Google are creating competitive equivalents. Slack needs to find a "secret sauce" that can differentiate them further."
"I would like the in-meeting content sharing facility to be improved."
"Slack could add additional and better integrations."
"It would be better if Slack had a 'select all' option to delete all the files."
"The solution needs to improve its scalability."
"Some features and plugins can be pretty obscure or difficult to deploy."
"It is difficult to navigate the tool when I log in to two devices and start a video call."
"The only con was that it did not share the same transition speed between apps as SAP StreamWork, another platform that I reviewed in the CODIE Awards collaborative category."
"Customer Service: Good through YCN, but sometimes I got frustrated by translation issue."
"Cannot import or invite bulk users from an Active Directory security group."
"Yammer's UX and UI are areas with certain shortcomings where improvements are required"
"We tried to integrate into SharePoint, but it was not really efficient."
"Perhaps keep working on the integration of other Office products."
"There is room for improvement in the customization and administration aspects of the product."
"The solution must be able to stream by itself, without integration, the same way that you are able to do it on Facebook Live, Instagram, etc. Streaming must be embedded into it."
 

Pricing and Cost Advice

"Slack is definitely worth the money."
"The solution is expensive."
"We use the free version that does not have a license."
"The tool's pricing could be cheaper."
"It is less expensive than one of its competitors."
"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."
"When it comes to pricing, it is on the expensive side."
"It is an affordable solution."
"I think that there is a need to make yearly payments towards the licensing costs of the solution."
"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."
"The pricing is not bad."
"Compared to other products like Amazon, Yammer's pricing is fine."
"Yammer is a pretty cheap solution, and it's included in multiple subscriptions."
"Its cost is included in the license bundle for Microsoft."
"I don't know about the pricing. Now that Microsoft has bought Yammer, it should be a part of our subscriptions for Office 365."
