Positive: The virtual workspace created for a work team within the same company, for the resemblance of information and communications in one place.Negative: The access for members of a non-profit organization who have external emails from the host but need the same access as an internal person since their volunteer work is part of the very core of the federation.

I would definitely recommend Slack to everyone who needs a messaging platform for work. The thing that I most appreciate on Slack is the possibility of talking to my coworkers without using my personal number or personal apps. This way, I can separate what is work and what is not. Slack even has the option to mute notifications after work hours. I'm able to keep track of every project and discuss them in an easy and fast way. Another great thing is that you can keep and check the history of channels and groups, this way the discussions are never lost when someone joins the project in the middle of it or someone leaves, the history is always there. The only thing that bothers me in the platform is the system of threads, where you can easily lose the messages cause they look kind of hidden. If you have multiple subjects with someone and the person only responds in threads, it's very common to lose their messages.

Pros
Microsoft
  • Virtual meetings - ease of set up and execution
  • File sharing! We build channels for projects, and being able to invite only project members is huge!
  • Peer-to-peer communications - being able to "ping" one of my colleagues, either text, video or call-only, on-demand, is what runs our business.

  • Automated Notifications: Integrated tools like Jira, Trello, and Google Drive to receive automated notifications and updates directly in Slack, improving visibility and efficiency within the team
  • Message Encryption: Slack encrypts the messages in transit and at rest, ensuring the security and privacy of sensitive information and making our IT team's life much easier.
  • Reminder Bots: We used Slackbot to set reminders, automate follow-up actions, and provided information based on user queries.
  • SurveyMonkey Integration: Integrated our Slack with SurveyMonkey to distribute surveys and collect feedback from team members, streamlining the feedback-gathering process which was a huge support to our HR and Admin team.

Cons
Microsoft
  • The feature of notifications in the mobile application could be improved. Sometimes notifications of different teams are not visible and are only visible when the application is opened.
  • It uses lots of computational resources while running and thus, slows down the system sometimes.
  • It allows a few channels per team. The number of channels could be increased for better productivity.

  • I do wish Slack made it easier to see your DM's. They added a feature that moves them around based on who is active, but if you're trying to find a thread with a teammate who isn't active on Slack at that moment, it's a lot harder to find.
  • I also think they could integrate with AI more and have apps for AI.
  • Lastly, it would be awesome if it would tell you when a coworker was last active. It would be nice to keep track of when people are logging off.

Usability

User experience has been much better than the previous Skype for Business app. It has an easy-to-use interface with persistent chats. The search feature is very fast and useful. MS Teams has mostly focused on Collaboration and team building features which are very useful for organizational communications. Since Teams is accessible from multiple platforms like Laptop, Desktop, Mobile phones, etc it has been very convenient from a Mobility perspective.

As long as you use the basic chat features and nothing more, it really is super easy to understand and use. Once you want to take advantage of some of the more advanced features and capabilities, that's when things get complicated. Anyone who has use SMS or a chat program before will be able to figure out the basics though, so rolling this out should be relatively straightforward and not required exhaustive training. Teaching chat etiquette is something else though.

Using Microsoft Teams has resulted in much faster business communications with both co-workers and consultants. There has been little need for support with this software as the interface is very intuitive and the product is overall very well designed. We did encounter an issue with the built-in phone service, however, this was quickly resolved by the support team.

I've never had to contact support for Slack which is a great testament to its ease and use. Adding people outside of the organization takes a little getting used to, but ultimately allows for greater collaboration between FTE and contractors. There is no clear alternative to this software, so it's the best we can do for now.

Our company and IT department previously used Skype for our communication needs. Skype was not dependable in my opinion, because it seems each time I used it during a call and/or a meeting, I and several other team members would get disconnected more than once. This caused a great interruption of our meeting, caused team members to have to ask others to repeat themselves and caused a general lack of interest in employee attendance during meetings.
