Yammer provides a social network experience for the enterprise, providing a "Facebook for work". Its mobile app provides an excellent user experience, showing the full mix of communications happening across topics and teams. The web app, while it hasn't evolved much in the last few years, provides a good experience consuming news. Personally, I use Yammer every morning to see what's happening across my company and comment, like, and share to interact across silos. As long as the size of the network inside of Yammer is managed - likely partitioning a large organization into business units, etc., - then Yammer provides an excellent platform for social news and "bottom up" collaboration across teams. Its free-form posting style, including articles and polls for interactive content, helps break down silos across the organization. Contrasted with the boring world of email, Yammer is a tantalizing world of pictures, GIFs, and videos. At LiveTiles, we share company and team news via Yammer, enabling others to see the progress and milestones - from a new office to a new customer - without the heavy burden of a company newsletter or similarly curated content. Even though we have fully adopted Teams for day-to-day, intra-team communication, Yammer is still the gold standard for inter-team communication.
Slack is really effective for smaller teams to use as an internal communication platform. I think that it's still suitable even for companies of up to 500-1000 employees, but for larger teams it's less appropriate (or would require more aggressive organization, e.g. keeping channels protected and on an invite-only basis). It's really helpful for small team-to-small team communication too (like in our case where we create external channels to support POCs/business partnerships). It's not great for direct collaboration (e.g. it's hard to iterate on a project spec or a document together, directly in Slack) but it's well suited for conversational coordination, like planning meetings or asking informational questions.
No one likes getting a long thread of reply-alls. With Yammer announcements and updates can be shared — without cluttering your inbox.
Yammer's mobile apps are great for our on-the-go sales team to stay in touch with our office staff.
Yammer's social aspect makes it incredibly easy to use, even for our less tech savvy teammates. If you've used Facebook, learning Yammer will be a cinch.
While Yammer has been an easy transition from SharePoint, it's still relatively new and unknown. Some employees claim that feel like the product was just another "add on" to the entire Microsoft Office experience.
When introducing new employees to Yammer, they are not as receptive because of how widely used SharePoint is across businesses and industries.
Functionality is simple, but still vastly different from SharePoint, thus creating a learning curve.
Undoubtedly Slack’s search function is powerful but sometimes it is difficult to find specific messages or files in very active channels with high message volumes. This needs an improvement.
I have experienced notification issues on my phone. I am not receiving notifications and have missed important updates as a result. I tried uninstalling and reinstalling the app, but the problem still persists.
The Business Plus plan does not include support for data loss prevention or offline backup providers.
Microsoft is dedicated to continual improvement on Yammer. They realize the value that Yammer brings to the table with their clients. In the short time that we have had Yammer implemented, we are just now beginning to see the strong impact it has on becoming more effective and efficient around collaboration.
Slack sitll lacks in functionality. It's better than Skype for Business in many ways, but it is still another chat/message board app. It has limits in free version and paid versions. Also Windows app has errors that bother me, for example, I see number on one of my team's icons. It suggests that one of channels has unread messages; I check all channels - no unread messages, but that "1" still appears
Overall easy to use and intuitive, although limited in the possibility to personalize layout and look & feel of a site. Some functionalities are not easy to use, like document editing, but some others are quick and effective (posts and tagging above all). Performance and responsiveness of the Yammer site is typically acceptable, in my experience.
Yes, the app works 24/7. I don't even recall having any period that we could not use since the implementation. Even the maintenance periods are barely noticeable and our work is not impacted by it when it happens.
Slack is a soft app, we don't have many issues with it. I recall one or two people complaining about something during our usage period, but I didn't have a bad experience. When the app is slow, usually the problem is with my computer or my internet. The app works just fine.
We have never had to use the support for Yammer. The tool works well and we have not come across any bugs. User Interface is simple and easy to use, similar to other forum type products, thereby removing the need for any extensive training. Team members are invited in and immediately are able to start using the tool.
Whenever I've had to troubleshoot an issue with Slack (which, to be honest, has not happened very often), their online documentation has been easy to locate, easy to understand, and effective in resolving my issue. Slack's ever-growing popularity also means that there's a large community of practice out there that can be depended upon.
I like how Yammer has functions that are fun and interactive, which can give you much more to do than using Teams or even Microsoft Forms. Yammer helps people feel included and gives people a better sense of how their friends and co-workers are feeling on certain issues. Yammer is a lot more like a social media platform than a work tool even!
I like Slack better than ClickUp, because I would spend 30-60 minutes a day updating my ClickUp tasks. The way ClickUp was used was very micromanaging. I billed by the hour, so I was willing to put in the time to alert the boss what tasks I was working on.
One of my jobs used Hive - I mostly just ran it in the background in case anyone messaged me. I did not use it often.
Nothing negative. But what we tend to forget is that Yammer is just a product, not a vision for change. The true and deep implementation and adoption of an enterprise network needs work and commitment, just like everything else. The true benefits will only emerge over time.
Slack has been incredibly helpful in connecting various tech apps and ecosystems, creating a more streamlined and responsive process.
Slack has made it significantly easier to communicate with our team members across multiple time zones, creating a more engaging environment for our all-remote team.
