Slack is great for use on teams, where quick and casual communication is appropriate. It's easy and enjoyable to communicate with this venue. I could see it working amazingly for startups and smaller teams throughout all levels of the organization but I think for larger organizations with a more formal hierarchy, this tool might not get used across levels as much.

Zoom

Zoom is well suited anywhere you have people in various locations - whether they are employees, contractors, customers, or prospective customers. Zoom is not well suited where internet connectivity issues exist. If there is questionable service, call quality degrades and it's advisable to disable the video portion of the call. It would be nice to have something in the UI suggest that a user disable video if their connection is unstable - perhaps?

Pros

Slack

  • Keeps project conversations localized and easy to find. The channels are able to be search so you can find older things that were said before you joined the channel or something you need to refresh yourself on.
  • Has some voice calling too so that if you're not able to explain your message well enough through the text, you can call the person directly from Slack on your computer or mobile app. Great for remote workers to feel like they are still connected.
  • Has some fun features like bots for birthday reminders, emoji's and gif images to share.
  • The app works great, allowing you to jump between different Slack teams very easily and notice when there are notifications that you haven't seen access teams and channels.

  • Zoom is extremely easy to set up. It only took about 3s from downloading to installing.
  • Zoom is extremely small. The download was tiny, less than 10MB in size!
  • The call quality with a reasonable internet connection is extremely good. I've rarely had issues with call quality.

Cons

Slack

  • Desktop app uses a lot of system memory.
  • Cost per user is a quite a bit higher than competitors.

Zoom

  • Zoom could do a better job with moving some of the calls to action buttons in easier to see areas. Every now and then folks can't initially find where to click to share their screen.
  • I'd like to the ability to paste images into the chat.
  • It would be nice if the chat transcript could be downloaded for the host. I haven't seen this offered.

Slack sitll lacks in functionality. It's better than Skype for Business in many ways, but it is still another chat/message board app. It has limits in free version and paid versions. Also Windows app has errors that bother me, for example, I see number on one of my team's icons. It suggests that one of channels has unread messages; I check all channels - no unread messages, but that "1" still appears

Some apps offer a great desktop experience but have more limited mobile functionality. Others are the reverse. I find that Slack does both tasks equally well and presents a perfect UI for either format. I have experienced downtime with Slack before but outages are rare and they get things back up quickly.

Everything is easy to understand and use, new users need no training. On the flipside there are minor annoyances such as calendar export being cumbersome (need re-auth every time) and also not having recordings shared within a team or forcing people to name them.

There have been less than a handful of outages during our two years with Zoom, and whenever there was one, an email informing us of the outage went out immediately, and they had the issue resolved shortly thereafter.

Zoom has among the best performance of any video conference platform, as I've mentioned several times. Besides that, their Chat platform works great, and their back end always runs smooth. It's unfortunate that reporting can now only be done by one month at a time, but nonetheless, it only takes a second to run any kind of Zoom report, whether it's an attendee report, Poll results, a user report, a list of meetings from the past month, etc.

Have never had the pleasure of using Slack support so wouldn't know, but I've heard good things. It's really an achievement when a SaaS product is so good, you rarely need to contact support (if ever). What I find useful is that Slack always make the customers aware if they are down through their status page and Twitter.

Zoom's support is truly world class. And I'm not sure if that's because my company was an early adopter, but nonetheless, they're very helpful. If we encounter some kind of bug (a rare event), it's not long before the engineering team gets back to me with a fix. If I want to submit a feature request, a rep gets back to me instantly saying that it's now on their scope (and then it gets added to the product shortly after). If I have a question about some feature, Zoom support always has a speedy answer.They're very good at giving detailed release notes any time there's an update, and their documentation is always great.

If you receive any pushback from higher ups, point to any of the various positive reviews like this one. Or show Zoom's excellent Gartner report, or articles describing Zoom's partnership with Sequoia capital. It's not difficult to show how Zoom is a trustworthy industry leader with best-in-class technology.

Alternatives Considered

Slack

Group collaboration and communication with Slack is a far superior solution to any business organization. It is extremely easy to use and adoption of the service is simple. With the alternatives, when we trialed them we found it harder to gain traction amongst our technical teams.

Zoom

Zoom blew all the others (GoToMeeting, Skype, Google Hangouts, UberConference) out of the water. Free consumer solutions didn't have the reliability, scheduling, privacy, recording, or headcount capabilities that Zoom boasts. GoToMeeting and Webex are old and clunky to use, though everyone already has the software installed it seems. UberConference was SUPER flaky. It had terrible connections whenever we did calls outside of NA, especially to Israel. Buffering, audio cut outs, etc. Zoom was everything we wanted at a great price point.

Because the Basic licenses are completely free, and because it's very easy to configure and install Zoom, and because anyone can join Zoom from a link without needing an account, scaling is a Breeze. There are absolutely no roadblocks. My company keeps adding more Zoom Pro license every week since it's so in demand. We were able to convert users from several different platforms onto Zoom with no trouble at all.

Return on Investment

Slack

  • Positive: The ability to maintain a constant point of contact to anyone in the organization.
  • Positive: The ability to maintain an archive of company communications.
  • Positive: The ability to have "guest" users that don't actually use a paid license.

  • Zoom has revolutionized my business. I am now able to have live contact with students, and this has helped me to improve my classes.
