    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.

    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.

    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.

    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 ideal for Scrum and agile teams that need continuous communication during sprint planning, daily stand-ups, backlog refinement, testing, and retrospectives. Slack is well-suited for maintaining team knowledge through searchable conversations and dedicated channels, where experienced team members help onboard new QA analysts.

    Pros
    Microsoft
    • Providing a platform for social news in the company where "bottom up" topics can percolate freely across department
    • Social networking across the company where folks can divide their work into topics instead of teams
    • Basic collaboration within a group including document sharing with ability to pin documents to a team

    • Customer issues: Threads feature allows us to group a particular issue in a single thread and discuss within that thread. I can use the thread link to embed in JIRA ticket for tracking progress in JIRA (which is our details engineering tracking system).
    • Ability to add folder to Slack channel helps keep important information, documents easily accessible. e.g., we use this to keep a "ramp up" folder that can be used by any new joiner.
    • Global search is effective when I forget which group a particular message was in.

    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.

    Slack has good usability. Devs that are not familiar with the platform are able to jump into conversations and start sharing code and links within just minutes. Non developers are also able to understand the layout such as the Project Managers that are keeping the projects on track. We have not seen any tickets where employees are having trouble understanding Slack.

    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.

    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.
