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

"Its integration with different apps is a great feature."
"Slack is very supportive in terms of communication between my colleagues and clients."
"Slack is a powerpack bundle of features that help small or large organizations to handle teams and their tasks."
"The solution makes it easy to create groups, share documents, and communicate."
"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 Business - Enterprise has had a positive impact on our organization with better communication, provides faster response times, fewer emails, and has helped create a more agile company."
"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."
"I use Slack for communication with my colleagues."
"People share their files and ideas and attend meetings in a collaborative manner."
"The most valuable feature of Yammer is its integration with all the services of Office 365."
"The product's initial setup phase was straightforward."
"Yammer allows collaboration anywhere, anytime, on any device."
"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."
"The most valuable feature of Yammer is that it provides integration with Teams."
"The most valuable feature of this solution is the communication events."
 

Cons

"The notifications on the phone are delayed."
"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."
"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."
"Slack could add additional and better integrations."
"The product should provide integration with other solutions like Gmail or Outlook."
"I haven't experienced any noticeable return on investment since starting with Slack."
"Customization is something that Slack is lacking."
"Slack feels clustered and hence it should improve its design and UI."
"Users need to be in the Acting Directory to exploit the features."
"Although Microsoft is working on it, having a centralized network instead of creating multiple networks based on a domain would help businesses with multiple companies or child companies."
"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."
"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."
"It has a very limited use."
"I would like to see a fancier user interface. That is one of the weak points of Yammer."
"The permissions are a little bit over-complicated."

"Slack is definitely worth the money."
"It is an expensive tool. We pay 15 to 20 USD monthly per user."

"I think that there is a need to make yearly payments towards the licensing costs of the solution."
"The pricing is not bad."
"Compared to other products like Amazon, Yammer's pricing is fine."
"Yammer is a pretty cheap solution, and it's included in multiple subscriptions."

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