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

"Slack is a very stable product."
"I like the tool's ability to send voice mail. We can also search for conversations easily in Slack."
"Overall, it is a good idea as it works better than most solutions out there."
"It has improved my company by letting our team work efficiently together and quickly."
"It has become easier to use than Teams, which is the main benefit of Slack Business - Enterprise; it is simple and connected."
"One thing I like about Slack is the ability to change the color of Slack. It depends on my mood. When I'm having a bright day, I just change the background color of my Slack, which is nice."
"The integration with third-party automation services such as IFTTT and Zapier has significantly boosted productivity."
"We use Slack for general communication, conference calls, and sharing screens because we have people working from different countries."
"The most valuable feature of Yammer is that it provides integration with Teams."
"The initial setup was simple and straightforward."
"Yammer is suitable for an organization that has many branches or offices."
"I have found it to be a good tool for building communities and for improving communication."
"Valuable features include the integration with Microsoft Office and the fact that it is in the cloud. Also, it's quite easy to use."
"The most valuable feature of Yammer is its interface."
"The design of the solution is its most valuable feature."
"Communication. We are able to communicate and keep in touch with a global audience."
 

Cons

"Slack is not as strong as competitors like Teams when it comes to things like video meetings and audio meetings."
"The solution needs to improve its scalability."
"For me, the only thing I can say is that every time somebody sent me an attachment, the attachment was listed somewhere, and then I had to open the conversation and go to the individual to open it. So there is no handy repository or an easy way to quickly look at attachments. For me, that was a bit difficult."
"The integration with SharePoint doesn’t work properly."
"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."
"Slack does not have videoconferencing capabilities, which would have been nice."
"The tool has stability issues that need to be improved. We are not native English speakers and Slack needs to integrate grammar checks."
"Better ways to help people get up to date when away from a conversation for a long time, or after bursts of a particular discussion."
"Integration with other Office 365 products is still weak, because Yammer initially wasn't a Microsoft product."
"There needs to be access to a channel, without the need to sign-in."
"The way you want to control the communication could be an issue. It depends on what kind of company you are. We are a public company, and there are some regulations that we need to comply with. Its ease of use can be an issue for a company because anybody can subscribe and use it. There are many competitors that are overlapping. Since Microsoft bought Yammer, it tends to be in the shadow. It is not put in the front from the service perspective."
"The product seems to just add to the complexity of using existing tools."
"MS made us plenty of promises for Yammer and have not delivered."
"There's always going to be room for improvement, because it's not the answer for everything."
"Technical support specifically gets a fair rating."
"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."
 

Pricing and Cost Advice

"The solution’s pricing is cheap."
"When it comes to pricing, it is on the expensive side."
"I would rate the tool's pricing a four out of ten."
"Slack is definitely worth the money."
"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."
"The solution is cheap in my country."
"The tool's pricing could be cheaper."
"We use the free version that does not have a license."
"I don't know about the pricing. Now that Microsoft has bought Yammer, it should be a part of our subscriptions for Office 365."
"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."
"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."
"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."

Yammer vs. SP Social in 2013
There are several discussions on SharePoint’s social strategy going on at the moment. I had some great discussions with my MVP mate Adis during Summit last week. Since #SPC12 almost every SharePoint addicted developer, it-pro, power user has reviewed Yammer. If you don’t know what Yammer is, here a…
