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

"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."
"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."
"It has become easier to use than Teams, which is the main benefit of Slack Business - Enterprise; it is simple and connected."
"I like Slack's notifications. It is more user-friendly and pleasing than Teams."
"The integration with third-party automation services such as IFTTT and Zapier has significantly boosted productivity."
"Its intuitive design makes it easy to use and understand, hence we do not have a need to spend much on educating our teams."
"With respect to being a clean and efficient communications platform, I think that it does the job quite well."
"Our internal team primarily used Slack for communication with each other, and if two or three people were working on the same modules then they were able to share code and work together."
"It has improved information sharing across the company which allows for problems to be solved much faster."
"Yammer provides a simple to use, intuitive platform for enterprise collaboration within the social networking information model."
"The product has allowed cross-functional discussions across every business group throughout the company."
"There are so many features, everything you could ever want, which is great for team collaboration."
"Yammer saves our time because we can communicate with a lot of people at the same time without sending a lot of emails."
"The most valuable aspect of the solution is that anyone can post anything, it's free and people can do it on their own without having to translate to publish, and it's really easy to use."
"It was reasonably good at creating online communities of interest."
"The user interface and the way we can share and search information are the most valuable, and it is very easy to use."
 

Cons

"According to my observation, a large size file sharing feature is what can be expected, which will centralize all activities within Slack and that can save a lot of time."
"Customization is something that Slack is lacking."
"Slack's channel and chat management could be more intuitive."
"The tool has stability issues that need to be improved. We are not native English speakers and Slack needs to integrate grammar checks."
"When scaled on a large scale, the solution's cost becomes a matter of concern for organizations."
"We’d like it to have more capability for everyone to work on one doc in real time all at once."
"The tool should be able to fetch a conversation when we search for it even if it is in the thread."
"Microsoft and Google are creating competitive equivalents. Slack needs to find a "secret sauce" that can differentiate them further."
"Yammer should be able to integrate with Microsoft products, such as Outlook."
"Yammer should offer flexibility to allow branding without writing any code."
"MS made us plenty of promises for Yammer and have not delivered."
"Yammer is not as feature rich as the most mature offering in this space, Jive, however it makes up for this with strikingly intuitive ease of use and a much lower cost."
"It needs more support for third-party apps."
"Cannot import or invite bulk users from an Active Directory security group."
"Perhaps keep working on the integration of other Office products."
"This solution would be improved if it was well integrated with other communication applications."
