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

"The product makes communication seamless."
"Slack is a powerpack bundle of features that help small or large organizations to handle teams and their tasks."
"I use Slack for communication with my colleagues."
"When we work with a platform like Slack, we can have one source without merging different document versions."
"We use Slack for general communication, conference calls, and sharing screens because we have people working from different countries."
"Slack is a very collaborative tool that makes it easier for me to communicate with the onboarding and billing teams."
"Overall, it is a good idea as it works better than most solutions out there."
"The ability to create ad hoc channels for certain projects has made us more effective."
"I have found it to be a good tool for building communities and for improving communication."
"The idea crowdsourcing features are valuable because they show the business benefit of this social tool."
"From the point of view of knowledge sharing, we created a group per project, and while we had SharePoint for storing documentation, we were able to link to these and give them content in Yammer."
"Co-workers feel comfortable creating groups for collaboration, communication, and non-work related, personable groups."
"The integration with Teams is the biggest value for us."
"Productivity can be increased as colleagues from across the world share their knowledge and experiences, reducing the need to create deliverables that may have been previously created."
"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."
"We have been able to have multi-country project teams where members can interact in their own language."
 

Cons

"Archiving for direct messages made tracking back conversations very difficult once the group started to grow large."
"We do experience issues when trying to log in on Slack."
"Honestly, I feel like I am nitpicking when I say the UX can be improved."
"The product is stable, but you need an online connection."
"Their notifications are generally not very prompt. There is a problem with their notification engine, and sometimes, I end up pressing on notifications."
"Integrating Slack with calendar functions would be advantageous, allowing for the seamless scheduling of meetings within the platform."
"They could improve the calling quality."
"The reason is we are moving towards a new CRM, so we have a suitable solution to integrate with the new CRM."
"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."
"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."
"They need to somehow enable better document sharing features. They need to provide joint drafting of documents."
"Yammer's UX and UI are areas with certain shortcomings where improvements are required"
"With the release of teams and groups, Yammer is losing its purpose slightly."
"This solution would be improved if it was well integrated with other communication applications."
"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."
"Yammer should be able to integrate with Microsoft products, such as Outlook."
 

Pricing and Cost Advice

"I would rate the tool's pricing a four out of ten."
"It is an affordable solution."
"It is an expensive tool. We pay 15 to 20 USD monthly per user."
"It's on the more expensive side."
"The solution is cheap in my country."
"The solution is expensive."
"The tool's pricing could be cheaper."
"Slack is definitely worth the money."
"I think that there is a need to make yearly payments towards the licensing costs of the solution."
"The pricing is not bad."
"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."
"Its cost is included in the license bundle for Microsoft."
"Compared to other products like Amazon, Yammer's pricing is fine."
"Yammer is a pretty cheap solution, and it's included in multiple subscriptions."
"I don't know about the pricing. Now that Microsoft has bought Yammer, it should be a part of our subscriptions for Office 365."
