Microsoft Yammer

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

Slack is best suited for scenarios when you need to start a conversation with any person you know or don't know. Because notification are quite fast and possibility of getting replies on DM is more than any email.Also Slack it's less appropriate for cases when you need to share large files/codes, because you can't view all the data without downloading it in your system.

Pros

Microsoft Yammer

  • Employees from around the globe get to follow, share and discuss a myriad of business topics on Yammer, our business social network. They get to start conversations, collaborate on files and organize projects so one can go further, faster. Plus the ease of asking questions, finding expertise and offer feedback on a topic without leaving the application you’re in saves time and keeps employees engaged.
  • When one works with teammates in Yammer groups, ideas fly! Do you have an important message to share with the rest of the community? We utilize Yammer to reach who you want within the company when you want, so no one misses a thing. Yammer brings the global conversation straight to you.
Marcos Sola | TrustRadius Reviewer

Slack

  • Communication with members of a project ( via channels features where you can create specific dedicated groups for project members only)
  • Third-party app integration ( Integration with Asana, Gmail, JIRA, GIFy, etc.)
  • Daily Huddles - This has been one of the latest addition to the features, and this has been liked by all of our team members. It makes running daily huddles super easy, considering the WFH environment that we are in.

Cons

Microsoft Yammer

  • Editing functionality would be warmly welcomed by my team. There's currently no way to edit posts in Yammer once they've been posted. If a typo is bothering you, you'll have to delete your post and re-post with the edited text.
  • Yammer's design leaves something to be desired. Document editing is not great.
  • No obvious way to sort/organize files uploaded to Yammer. If files from a certain user are needed, you'll have to go to their profile and sift through their uploaded files.
Kyle Legg | TrustRadius Reviewer

Slack

  • You can have a voice call with you team. But, it's better to have a video call function.
  • Sometimes it's hard to find the direct message in threads.
  • When opening the software and app. The refresh rate after logging in is slow.
  • If you manage 2 businesses. You can't manage them in one platform because you need to create a separate Slack link for it.

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.

As useful as Slack has become within our company, I feel fairly confident we will continue to use Slack as a communication tool. They continue to improve their software and add value to its use within our office. Customer service delivers, which is an absolute must. Looking forward to how they improve.

Usability

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.

As long as you use the basic chat features and nothing more, it really is super easy to understand and use. Once you want to take advantage of some of the more advanced features and capabilities, that's when things get complicated. Anyone who has use SMS or a chat program before will be able to figure out the basics though, so rolling this out should be relatively straightforward and not required exhaustive training. Teaching chat etiquette is something else though.

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.

I've never had to contact support for Slack which is a great testament to its ease and use. Adding people outside of the organization takes a little getting used to, but ultimately allows for greater collaboration between FTE and contractors. There is no clear alternative to this software, so it's the best we can do for now.

It always helps if you communicate to everyone in the organization how important it is to drop whatever other chat tools they are using and jump quickly to Slack. They will all fall in love with it.

Alternatives Considered

Microsoft Yammer

Microsoft Yammer far exceeded expectations when the company I work for switched from SharePoint. There was a limited learning curve, and a bit of training need, but generally the transition was smooth. SharePoint, while it proved to be useful company-wide, we have found that Microsoft Yammer creates more of a social network within departments. Microsoft Yammer provides a personal employee communication and information sharing

Slack

Slack has expanded functions and much better connection. Slack is heavily customizable whereas 3CX and Google Chat are standard across the board. To my knowledge 3CX and Google Chat do not have the thread function, expanded reactions function, group channels vs group messages, profile photos/titles for users, or customized viewing preferences

Return on Investment

Microsoft Yammer

  • Adoption. When an ESN is implemented the wrong way, e.g. you force it on the organization without explaining the benefits for the user and not providing enough instructions and training to get started, it may well backfire on you and build a wall of resistance from the organization. Thus, to create ROI you need to think before you launch Yammer, and take help from people who know how to do it, e.g. a CSM or a CM.
  • Belonging. Yammer makes people feel more involved and up to date on what's happening. This increase employee engagement and helps management to steer the organization in the right direction.
  • Find blind spots. Yammer enables people to share ideas and prototypes with many people both within the company and invited customers (via an external network). This is a great way to discover blind spots and other flaws, to give you time to adjust them before going to market with a new product or service.
  • Find expertise. Yammer makes it much faster for anyone to find answers. Thus, time spent on finding an answer to a customers questions is not only reduced enormously, but Yammer enables you to get answers to questions that earlier was left unanswered because you couldn't find information at all.
  • Collaboration. To work together to create a presentation, social media content, a newsletter, a report, is much easier and faster when using Yammer. And you can get valuable input from people you never thought of asking.

Slack

  • Positive -> Easier collaboration as and when required with the ease of use of the tool.
  • Negative -> Too much communication (partly because of the ease of use) which might result in introducing a lack of structure and makeing it overly informal.
