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's categorization of content and the availability of channels are highly valuable, as they keep communications organized."
"Its integration with different apps is a great feature."
"The product makes communication seamless."
"The most valuable features are video conferencing and sharing content during meetings."
"The huddle feature is valuable to me."
"When we work with a platform like Slack, we can have one source without merging different document versions."
"The most valuable features of Slack are basic chatting, file sharing, and screen sharing."
"Slack is a very collaborative tool that makes it easier for me to communicate with the onboarding and billing teams."
"The posting features are valuable."
"The product's initial setup phase was straightforward."
"I find it quite simple and intuitive. It's similar to using a more user-friendly interface for SharePoint. It integrates seamlessly with the browser, so you hardly notice you're using it."
"Groups is the most valuable feature in Yammer."
"The most valuable feature of Yammer is that it provides integration with Teams."
"It was a stable solution...It was a highly scalable solution considering it was used in a very big company."
"Yammer is useful since it is a product you can easily integrate into our system since Microsoft supports it."
"Its most valuable features are the storyline and communities."
 

Cons

"Sometimes there are login issues."
"Customization is something that Slack is lacking."
"I would like to see the social sharing of blogs, announcements, or other news directly from the message corner."
"I think Slack could add additional features without making the solution slower or more difficult to use."
"Slack does not have videoconferencing capabilities, which would have been nice."
"Slack could add additional and better integrations."
"The reason is we are moving towards a new CRM, so we have a suitable solution to integrate with the new CRM."
"It would be highly advantageous if it could incorporate calendar information from sources like Outlook or Gmail, providing users not only with meeting schedules but also a comprehensive daily agenda view."
"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."
"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."
"This solution would be improved if it was well integrated with other communication applications."
"I would like to see a fancier user interface. That is one of the weak points of Yammer."
"It has a very limited use."
"Microsoft should work on templating and provide some built-in templates so that the changes can automatically roll out to all the configured communities."
"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."
"Sometimes, we lose access to the solution for unknown reasons."
 

Pricing and Cost Advice

"The solution’s pricing is cheap."
"Slack is not the cheapest solution, but that's okay."
"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 tool's pricing could be cheaper."
"It is an affordable solution."
"The solution is expensive."
"It is an expensive tool. We pay 15 to 20 USD monthly per user."
"It is less expensive than one of its competitors."
"I don't know about the pricing. Now that Microsoft has bought Yammer, it should be a part of our subscriptions for Office 365."
"The pricing is not bad."
"Compared to other products like Amazon, Yammer's pricing is fine."
"Its cost is included in the license bundle for Microsoft."
"Yammer is a pretty cheap solution, and it's included in multiple subscriptions."
"I think that there is a need to make yearly payments towards the licensing costs of the solution."
"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…
