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 quick line of communication, most certainly improves the functionality of our organization."
"In the cases where it fits best with the team, Slack can be a replacement and enhancement to collaboration, increased productivity, and reduced clutter in email."
"Slack provides very fast communication."
"The huddle feature is valuable to me."
"Slack makes it easy for employees to contact each other and exchange documents or information."
"The most valuable feature for me was the different channels."
"The integration with third-party automation services such as IFTTT and Zapier has significantly boosted productivity."
"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 most valuable feature of Yammer is its integration with all the services of Office 365."
"Enables internal communication between different countries and locations."
"There are so many features, everything you could ever want, which is great for team collaboration."
"The tool allows us to post and keep track of company buzz and events without relying on email."
"The technical support is outstanding, and the Yammer team is open and responsive on issues, feedback, and suggestions."
"The initial setup was simple and straightforward."
"The product has allowed cross-functional discussions across every business group throughout the company."
"Yammer is suitable for an organization that has many branches or offices."
 

Cons

"Its capabilities to provide security features could be better for corporations."
"Slack's interface is not simple for me. It's not a user-friendly interface"
"The notifications on the phone are delayed."
"The product should provide integration with other solutions like Gmail or Outlook."
"The excessive notifications and distracting nature keeps it from being a perfect solution for me."
"There are a lot of features in Slack that I don't use, because I don't know about them."
"We are using the free version and some people from our team wish that the message history had not been removed, so if you sometimes need to go back a few months in a conversation, the paid version would be something to consider."
"There seems to be several minutes of delay between getting notifications on the Mac OS app and then receiving them on the iPhone app."
"Sometimes, we lose access to the solution for unknown reasons."
"We tried to integrate into SharePoint, but it was not really efficient."
"It looks slightly less clean on Chrome compared to Microsoft Edge, but it's a minor difference. There is room for improvement in user experience, like positions of elements."
"It just needs a more defined roadmap."
"There needs to be an "Edit" functionality for posts and replies because grammar and spelling mistakes do happen."
"Yammer can improve the effectiveness of its usage by addressing the metrics that measure user trust and perception."
"Yammer has very limited features."
"We had some scalability issues."
 

Pricing and Cost Advice

"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."
"It is less expensive than one of its competitors."
"The solution is cheap in my country."
"Slack is definitely worth the money."
"It's on the more expensive side."
"We use the free version that does not have a license."
"It is an expensive tool. We pay 15 to 20 USD monthly per user."
"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."
"Compared to other products like Amazon, Yammer's pricing is fine."
"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."
"Yammer is a pretty cheap solution, and it's included in multiple subscriptions."
"The pricing is not bad."
