Automation features and user-friendly interface support seamless communication
Slack is very supportive in terms of communication between my colleagues and clients. While working with the reimbursement feature, I found the automation capabilities on Slack to be incredibly useful, allowing me to automate messages for specific dates or times and even to greet someone on their birthday. I haven't specifically used the channel organization feature of Slack, as I am added to channels, but I use it with Airtable, which automates notifications to a specific Slack channel when a user fills out a form on our website. In my experience, Slack is a stable product for communication, and I appreciate its automation features and integration of AI capabilities for enhancing specific functions.

Quotes from Members

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

Pros

"The product has the ability to scale."
"Slack offers the ability to make customizable applications and plugins."
"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."
"Slack helps us keep the conversation focused and avoid multiple threads that create more confusion. I would say that has been the biggest advantage for us."
"Its integration with different apps is a great feature."
"It's valuable for announcements and communicating between team members."
"Slack offers several valuable features. Firstly, they have a message deletion feature, which is now available in other software as well, but Slack was the one who introduced it in enterprise solutions."
"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."
"Yammer brings in the most relevant posts to the users."
"It was a stable solution...It was a highly scalable solution considering it was used in a very big company."
"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 product's initial setup phase was straightforward."
"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."
"Yammer saves our time because we can communicate with a lot of people at the same time without sending a lot of emails."
"The user interface and the way we can share and search information are the most valuable. It is very easy to use."
 

Cons

"Slack is not as strong as competitors like Teams when it comes to things like video meetings and audio meetings."
"Slack should add a feature to schedule meetings."
"Slack tends to crash once a month."
"I want a feature in the solution that will help me share documents only with the set of people that I prefer rather than all of them. I would also like the solution to have a feature similar to Microsoft SharePoint where you can group all your documents."
"Integrating Slack with calendar functions would be advantageous, allowing for the seamless scheduling of meetings within the platform."
"It could be more stable than one of its competitors."
"The mobile app needs improvement. It consistently misses notifications."
"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."
"I would like to see a fancier user interface. That is one of the weak points of Yammer."
"It has a very limited use."
"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."
"Sometimes, we lose access to the solution for unknown reasons."
"This solution would be improved if it was well integrated with other communication applications."
"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 be able to integrate with Microsoft products, such as Outlook."
"Yammer's UX and UI are areas with certain shortcomings where improvements are required"

"Slack is definitely worth the money."

"Yammer is a pretty cheap solution, and it's included in multiple 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…
