A competitive solution that improves collaboration and productivity
Slack has been around for a long time, and it's an industry leader. Of course, Salesforce owns Slack now and is starting to integrate into it. I have attended Slack conferences and met with product and support managers. They're an excellent organization. Choosing Slack depends on the organization's size, so you need to plan your deployment and make sure you put some controls and standards in place and not just turn it on. If you're a Slack shop, you will have to have something like a Zoom or Microsoft Teams platform for when you need to do video conferencing internally or externally. Many shops have both products, but they use Slack for collaboration, chat, and so on, and use Teams for video and audio conferences. At the end of the day, Slack is missing those capabilities, so either you're going to be a Slack/Zoom shop or you're going to be a Microsoft Teams shop. I rate Slack an eight out of ten.

Ease of use and a familiar user interface
We transitioned directly from Workplace by Facebook to Yammer. From a front-end user perspective, they both look very similar and are easy to use. The main advantage of Yammer is that it's included in our Office 365 licensing suite, so it's a significant cost-saving compared to Workplace Facebook, which requires an expensive license.

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 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 definitively made an improvement on our productivity. Information does not got lost in hundreds of less important messages."
"The most valuable feature for me was the different channels."
"It allows to facilitate communication, allowing us to create channels for updates, file sharing, and photo sharing within our team profiles."
"The product makes communication seamless."
"The most valuable feature is that we can easily integrate different workloads and the alerts are reliable. Also because it allows us to use it as a monitoring tool sometimes."
"The portal is at its best version now."
"When we work with a platform like Slack, we can have one source without merging different document versions."
"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 that it provides integration with Teams."
"Yammer is useful since it is a product you can easily integrate into our system since Microsoft supports it."
"The initial setup was simple and straightforward."
"We can send out notifications and ask questions using Yammer."
"The product's initial setup phase was straightforward."
"Groups is the most valuable feature in Yammer."
"Its most valuable features are the storyline and communities."
 

Cons

"Customization is something that Slack is lacking."
"Slack's Canvas feature could be improved in terms of its user experience."
"Sometimes there are login issues."
"The only area of concern that I have is with the inability to preview received documents without having to download them first."
"The product should provide integration with other solutions like Gmail or Outlook."
"Slack tends to crash once a month."
"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."
"Slack does not have videoconferencing capabilities, which would have been nice."
"The interface is clunky and could be improved."
"The solution must be able to stream by itself, without integration, the same way that you are able to do it on Facebook Live, Instagram, etc. Streaming must be embedded into it."
"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."
"Yammer has very limited features."
"It should have integration with multiple third-party platforms."
"We tried to integrate into SharePoint, but it was not really efficient."
"Sometimes, we lose access to the solution for unknown reasons."
"The product seems to just add to the complexity of using existing tools."

"The solution is cheap in my country."

"I think that there is a need to make yearly payments towards the licensing costs of the solution."
