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

"It is easy to set up."
"The solution's initial setup process is easy."
"I like the tool's ability to send voice mail. We can also search for conversations easily in Slack."
"In managing releases via Slack channels, one major advantage over Teams is the ability to have threaded discussions, which helps in catching up on relevant discussions without the distraction of interleaved conversations."
"Overall, it is a good idea as it works better than most solutions out there."
"Slack makes it easy for employees to contact each other and exchange documents or information."
"Slack Business - Enterprise is beneficial for us primarily because the API was very beneficial, and that is the main one; the second benefit would probably be the upgrades they do, including integrating some AI and allowing customization of chats in categories."
"With respect to being a clean and efficient communications platform, I think that it does the job quite well."
"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."
"It has improved information sharing across the company which allows for problems to be solved much faster."
"The user interface and the way we can share and search information are the most valuable, and it is very easy to use."
"The solution was stable."
"I consider Yammer to be the best business collaborative tool."
"Its most valuable features are the storyline and communities."
"The product's initial setup phase was straightforward."
"We have been able to have multi-country project teams where members can interact in their own language."
 

Cons

"They could improve the calling quality."
"Sometimes, the servers are not available."
"We do experience issues when trying to log in on Slack."
"The reason is we are moving towards a new CRM, so we have a suitable solution to integrate with the new CRM."
"Honestly, I feel like I am nitpicking when I say the UX can be improved."
"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."
"There could be a read function so that when you send a message, instead of the other person having to add a reaction, you know that the message went through."
"Slack tends to crash once a month."
"The product seems to just add to the complexity of using existing tools."
"With the release of teams and groups, Yammer is losing its purpose slightly."
"The solution's feature for sharing could be better."
"Cannot import or invite bulk users from an Active Directory security group."
"Integration with other Office 365 products is still weak, because Yammer initially wasn't a Microsoft product."
"It has a very limited use."
"I would say the whole experience was negative, so that is why we stopped using it."
"There is room for improvement in the customization and administration aspects of the product."
 

Pricing and Cost Advice

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