    We have used 3rd party companies who have set up Unify for our customer sites and often it goes well. From a network perspective we often don't need to get involved too much and the set ups are often straight forward. This prevents us having to allocate engineers to new implementations.

    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
    Mitel Networks Corporation
    • Good integration with other system
    • Smart features and web applications
    • Good cloud and non-cloud options

    • 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.

    • 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

    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
    Mitel Networks Corporation
    Clients seem to understand new feature sets early on and we don't have to allocate too much time to training. This creates a low learning curve across the board which can be essential when implementing new communication methods. The call quality and application support is generally very good and we don't have many calls logged for issues.

    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.

    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.

    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.

    As we predominantly have a cisco environment we have used Cisco VOIP solutions in the past, which obviously integrate very well, however Unify does an excellent job at integrating into our networks with out problems and doesn't require too much manual configuring or changes.

    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.
