    Everything I've said previously. It takes me entirely out of the loop of coordinating people's schedules, sending invites, booking time, ensuring they get a Zoom invite, etc. It does everything while I do next to nothing, which is as it should be. As a team of one, my time …

    I was using Google Calendar before this to track my meetings but this one has several advantages over that. It syncs better with Outlook. It is easier to use. And you can automate a large part of your meeting set up. I don't know if any other software can do all of that.

    Calendly
    It's well suited for music students' lessons. It's well suited for online coaching, primarily through places like Zoom and more. It helps simplify things for your clients, lets you program your schedule, and allows it all to go automatically! If you are working with a senior population, it may be a little tricky for them to sign up and then really hard for them to cancel lessons. There isn't a way to go to the site and cancel. You have to pull up the confirmed email and cancel from there, but people can lose emails.

    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
    Calendly
    • Sync with multiple calendar types so my schedule is always current.
    • Integration with Zoom to schedule meetings, send invites, and populate my Zoom app accordingly.
    • Automatic email communication to all parties with all relevant details in a clear format.
    • Allowing team members to do the same in a way that I'm also notified of what meetings are taking place saves a lot of time in terms of coordinating to find out what other people are doing.
    • Well-designed interface that simplifies everything down to its clearest expression. Language instruction and interaction are wonderfully simple and clear.

    • 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
    Calendly
    • After a meeting is booked, having the ability to change the location without canceling the entire booking.
    • Being able to offer 2 different locked in locations for certain time periods of the day within the same event. So you're not having to create 2 events for the same thing, only different locations.
    • Giving users permission to create their own routing forms. We run an independent business model where our users like to have control over their subscriptions.

    • 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

    For all reasons like workflows, UI, and the way Calendly keeps all of us engaged through the Collective forum. It's indeed undeniable that no other product covers all business needs like Calendly does. On the other side, this has also reduced the workload by enabling us to focus more on other tasks for the day

    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.

    Calendly is extremely easy to use for selecting times and days for meetings. From my end, it's very easy to indicate the days and times that I am available for meetings. I have used other scheduling products, but Calendly has the smoothest way of operating. I highly recommend it for scheduling meetings

    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.

    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 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.

    • Positive: When people want to meet, I can simply send my Calendly link and it takes less than 5 seconds to do.
