Enables engaging communication with interactive features but requires improvements in reliability and meeting functionalities
I use Slack for internal communication between my colleagues and me at my company The integration with Google Calendar is easy to use and allows us to receive notifications before meetings. Slack is also very interactive, as it includes options for communicating with GIFs and a variety of emojis,…

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The solution has a great user interface and functionalities. It has good features that we can use. We can integrate any third-party application with Slack so that it provides you with insights and updates in real-time on Slack itself."
"The solution's most valuable feature is the search functionality, which I can use to search for full text."
"The product makes communication seamless."
"The solution is scalable."
"The portal is at its best version now."
"Slack is a very stable product."
"The most valuable feature is the screen sharing, which works well."
"I am impressed with the product's calls and screen share features which are very useful."
"The integration with Teams is the biggest value for us. In fact, it has only become more valuable now that it has integration with Teams. Teams allows you to stream, so that's good."
"It was a stable solution...It was a highly scalable solution considering it was used in a very big company."
"The most valuable feature of Yammer is its interface."
"Groups is the most valuable feature in Yammer."
"We can send out notifications and ask questions using Yammer."
"The tool allows us to post and keep track of company buzz and events without relying on email."
"People share their files and ideas and attend meetings in a collaborative manner."
"The design of the solution is its most valuable feature."
 

Cons

"When someone responds to my message in Slack, a new window opens. There should be an option to roll down the answers."
"The video calling experience on Slack needs improvement."
"We’d like it to have more capability for everyone to work on one doc in real time all at once."
"I would like to be able to do live streaming on Slack. Slack allows Slack huddle where you can do a group call, but it is not very well-designed. I'm not sure if it is going very well, but live streaming is one thing that I would definitely love to see. When you use Zoom, I like how you can run webinars. If we could do that through Slack, it would become an all-integrated platform. I would also like to be able to schedule meetings using Slack, similar to Zoom."
"It could be more stable than one of its competitors."
"I would like the in-meeting content sharing facility to be improved."
"Slack's screen sharing might also add the remote control feature, which is not there."
"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."
"We tried to integrate into SharePoint, but it was not really efficient."
"If you are using other applications that are tough to integrate into the environment, that can cause limitations."
"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 has a very limited use."
"It should have integration with multiple third-party platforms."
"I faced some issues with Yammer's mobile app when I shifted from Android to iPhone, and it got a little bit tricky to use it on an iPhone, which took away some of my time."
"Yammer should offer flexibility to allow branding without writing any code."
"I would rate the stability of Yammer as six out of ten."
 

Pricing and Cost Advice

"When it comes to pricing, it is on the expensive side."
"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."
"It is an affordable solution."
"The solution is expensive."
"I would rate the tool's pricing a four out of ten."
"It is less expensive than one of its competitors."
"We use the free version that does not have a license."
"Its cost is included in the license bundle for Microsoft."
"Yammer is a pretty cheap solution, and it's included in multiple 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."
"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."
"The pricing is not bad."

Since #SPC12 almost every SharePoint addicted developer, it-pro, power user has reviewed Yammer. If you don’t know what Yammer is, here a…
