Considered Both Products
Microsoft Viva Engage
Chose Microsoft Viva Engage
Yammer seemed like a lite powered Slack that was just coming into its prime. Still a ways to go, but integration with Office365 was great.
Chose Microsoft Viva Engage
Each app serves a different purpose even though there may be some overlap. Yammer is a little like Facebook and one can create, join, or find communities, and many people are familiar with Facebook. Slack works with channels and there are some people who are not as familiar …
Chose Microsoft Viva Engage
Yammer is very rudimentary as a broadcast tool and team notification. I has been surpassed in functionality and usefulness by all the other apps listed.
Chose Microsoft Viva Engage
Yammer created very important and reliable social network across the whole company. We used to have MS SharePoint, but since Yammer became available via Office 365 we moved to Yammer.

IBM Connections is difficult to maintain + costs are higher.
Chose Microsoft Viva Engage
Basically, all these applications have the same functions, to share jobs and projects in real time and have functioned very similar to social networks that are used daily such as Facebook, Instagram, and others. Yammer was chosen because it is very easy to use, fast and safe.
Chose Microsoft Viva Engage
Yammer, although not as strong for project management, has been a great tool to help our teams collaborate and build camaraderie across the organization.
Slack
Chose Slack
In comparison to Teams, I think Slack is a much nicer platform to use. If your technology department allows you to integrate third party applications, it can work really well paired with zoom, sharepoint etc. I think for many mid sized businesses it can be a good fit to enhance …
Chose Slack
Slack is the best office communications platform by far. It's lacking in the full integration of voice and video but the simplicity and ease of use for chat it is second to none.
Chose Slack
None of the competition coming from the Microsoft or Cisco provide the user experience of today's consumerized social media. Slack, on the other hand, is fully on par with the best and most known social media applications that consumers use. Consumerization of IT shows here as …
Chose Slack
Well we get Yammer with the Office 365 pack. So, Yammer is paid for and integrates well with Office. MS Office 365 does not have the type of ridiculous service interruptions that Slack seems to experience. Yammer does all the same stuff but without the bad user interface. I did …
Chose Slack
Overall I think it has the best collection of features in an easy to use interface that feels familiar to most people. I believe it is the only one that allows you to be a part of multiple teams and toggle between that with a simple click, which is great for our organization.

Microsoft
Yammer is great when you have a company culture that encourages friendly collaboration and communication. It can be a great supplement (but certainly not a substitute) for bonding and sharing ideas and thoughts. Certain channels can be really successful, too, like a channel where people can post dog pictures or something fun like that!

Slack is great for tracking commits to new coding projects. You can take parts of code that still need to be implemented later and easily search through the history of comments if there is something that goes wrong with a code commitment. It can be difficult for people that only like Teams to adjust to a new platform if you are using both to communicate.

Microsoft
  • Providing a platform for social news in the company where "bottom up" topics can percolate freely across department

  • Basic collaboration within a group including document sharing with ability to pin documents to a team

Cons
Microsoft
  • Although the social enterprise network works very well, there is room for some slight improvement - such as the ability to attract users. By being part of the Microsoft Office Suite, it is offered as an "add-on" and many overlook it and see it as unnecessary at first. It would be smart for Microsoft to sell it as its own product so it could gather more popularity as a "social network".
  • Giving an option to filter results could be better as well as giving an option to turn off the "recent activity" bar on the home page.

  • Would love a better integration with GitHub. For example, notifications when your PR is updated, when review is requested, @-mention in comments, etc.
  • Improved "Later" tab, for example the ability to create to-do lists or making the "Later" tab into a more powerful to-do list (annotate items with notes)
  • More powerful integrations, e.g. Google Calendar could render a calendar view within Slack, rather than sending the daily schedule

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.

To be more transparent, I give 10 because Slack serves our collaboration needs. It provide us a good platform for team communication relaying important update within the company, it has even mobile app where you can install in your phone to monitor any updates within that team that needs your immediate attention and intervention.

Usability
Microsoft
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.

My rating was 7. Its intuitive interface and user-friendly features like channels, threads, and integrations make it excellent for team communication and onboarding. However, its usability is held back by the resource-intensive desktop app and cluttered feeling in large workspaces. The mobile app's performance and unreliable notifications have also been noted as weaknesses.

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.

Support Rating
Microsoft
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.

Our team briefly used Salesforce.com's Chatter product before switching over to Yammer in 2012. While Chatter is essentially the same product as Yammer, it left much to be desired. Chatter's design was (and remains) clunky and difficult to navigate. Yammer is a simple, easy-to-use product that offers similar functionality as Salesforce's Chatter.

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.

Return on Investment
Microsoft
  • My company is pleased with the positive impact Yammer has created departmentally and on an individual basis with work flow efficiency.
  • Adversely, most old and new employees are more familiar with SharePoint, causing the company to pay for training for all current and incoming employees.
  • As Yammer becomes more widely used, the need for training may diminish, which is where we will see our return on investment, as the product clearly provides a more effective form of file sharing and communication between employees and their department.

  • 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.
