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 huddle feature is valuable to me."
"Initially I thought it cannot be better than Skype, but after working with it for a while I can definitely confirm it is a great tool for collaboration."
"The quick line of communication, most certainly improves the functionality of our organization."
"I am impressed with the product's calls and screen share features which are very useful."
"Slack is a powerpack bundle of features that help small or large organizations to handle teams and their tasks."
"Slack provides very fast communication."
"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."
"It is easy to set up."
"The solution was stable."
"Yammer is useful since it is a product you can easily integrate into our system since Microsoft supports it."
"People share their files and ideas and attend meetings in a collaborative manner."
"We can send out notifications and ask questions using Yammer."
"Its most valuable features are the storyline and communities."
"The user interface and the way we can share and search information are the most valuable, and it is very easy to use."
"The posting features are valuable."
"It was a stable solution...It was a highly scalable solution considering it was used in a very big company."
 

Cons

"I believe they can improve upon ‘calling’, which was introduced recently."
"Sometimes Slack behaves unexpectedly and shuts down without notification or support communication."
"There is some lag at times."
"The product is stable, but you need an online connection."
"The tool has stability issues that need to be improved. We are not native English speakers and Slack needs to integrate grammar checks."
"We could see improvement in Slack by having an integrated meeting tool. Currently, we rely on third-party integration tools like Zoom to schedule meetings. It would be much more convenient to schedule meetings directly within Slack without additional integrations. It needs to have calendar and CRM integrations as well."
"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."
"There are a lot of features in Slack that I don't use, because I don't know about them."
"The solution's feature for sharing could be better."
"I think that improvements could be seen in the delayed messaging, but other than, it's great!"
"Yammer can improve the effectiveness of its usage by addressing the metrics that measure user trust and perception."
"You can only search by words or person, you cannot filter by person plus terms, date, etc."
"We had some scalability issues."
"Ability to edit posts and also rich text would be good. Currently, unlike other social tools like Facebook at Work and Chatter, Yammer does not have the ability to edit posts."
"Perhaps keep working on the integration of other Office products."
"If you are using other applications that are tough to integrate into the environment, that can cause limitations."
 

Pricing and Cost Advice

"The solution’s pricing is cheap."
"I would rate the tool's pricing a four out of ten."
"It's on the more expensive side."
"It is an expensive tool. We pay 15 to 20 USD monthly per user."
"When it comes to pricing, it is on the expensive side."
"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."
"Slack is definitely worth the money."
"The solution is expensive."
"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."
"The pricing is not bad."
"Yammer is a pretty cheap solution, and it's included in multiple 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."
"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."
