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

"Mac version built into Safari has a lot of informative space and allows for custom CSS (right click > inspect elements) if you want it more personal and/or something puts you off in the standard settings."
"It's valuable for announcements and communicating between team members."
"The interface looks better to me, it is more easy to use, and everything is working okay for our purposes."
"We use Slack for general communication, conference calls, and sharing screens because we have people working from different countries."
"The solution's most valuable feature is the search functionality, which I can use to search for full text."
"If you're looking for an asynchronous/real-time communications tool, you will not find any app that comes close to Slack."
"It has not crashed once in three years, so I would say it's pretty good."
"You can create channels between teams internally and externally, which is great. There is a lot of security with Slack internal, which is what I value."
"Integration into SharePoint is a valuable feature as it provides better exposure and access to users."
"Productivity can be increased as colleagues from across the world share their knowledge and experiences, reducing the need to create deliverables that may have been previously created."
"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."
"I have found it to be a good tool for building communities and for improving communication."
"The solution was stable."
"It's really easy to use the solution."
"It was a stable solution...It was a highly scalable solution considering it was used in a very big company."
"In its simplicity, it has given our people across our organization and around the world a voice Helped people to network, ask questions, and get answers Helped people to share activity and best practices Segments liked-minded people together Creates engagement Allows people to give feedback and improve our culture"
 

Cons

"Notifications are not as good as they could be (especially for mobile)."
"Microsoft and Google are creating competitive equivalents. Slack needs to find a "secret sauce" that can differentiate them further."
"Slack should add a feature to schedule meetings."
"Their notifications are generally not very prompt. There is a problem with their notification engine, and sometimes, I end up pressing on notifications."
"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."
"The tool has stability issues that need to be improved. We are not native English speakers and Slack needs to integrate grammar checks."
"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."
"We tried to integrate into SharePoint, but it was not really efficient."
"Sometimes, we lose access to the solution for unknown reasons."
"It has a very limited use."
"The solution's feature for sharing could be better."
"I would rate the stability of Yammer as six out of ten."
"There needs to be access to a channel, without the need to sign-in."
"There needs to be an "Edit" functionality for posts and replies because grammar and spelling mistakes do happen."
 

Pricing and Cost Advice

"The solution is cheap in my country."
"We use the free version that does not have a license."
"When it comes to pricing, it is on the expensive side."

"Slack is definitely worth the money."
"The solution’s pricing is cheap."

"Yammer is a pretty cheap solution, and it's included in multiple subscriptions."
"The pricing is not bad."
"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."
"Its cost is included in the license bundle for Microsoft."
"Compared to other products like Amazon, Yammer's pricing is fine."
