Skype is useful for collaborations across distances, including work from home, as well as a more convenient way to communicate with a large group of people. Skype is also useful to communicate with specific parties quickly, rather than relying on cellular service in areas where not as available. Skype is less useful if the team does not use computers , tablets, smartphones, etc in daily workflow as it would rarely be used.

I think Slack works really well in office settings, or even for any group of people who need an easy way to communicate with each other through organized channels. It may not be the best for those who intend to use it as a social media type app, it is more geared towards business use.

Pros
Microsoft
  • Instant messaging to anyone who we know only by name/email. Even if they're offline, they get the message in missed convos and a notification automatically goes to them via Outlook mail. All conversations are saved and accessible via Outlook.
  • Video and voice calls are a norm in the WFH scenario, and an average employee has around 4-5 calls a day. Skype gives notifications for upcoming meetings, allows easy scheduling via outlook calendar, and its audio/video quality [is] reasonably good compared to the amount of data it consumes.
  • Status availabilities - in the WFH scenario, you could be off for lunch, out of office, busy, sharing screens - and might not want to be disturbed. Skype allows you to do that, and in case you're off, ensures that you know that you have missed messages.
  • Screen sharing - we have to share screens at least once or twice a day with a coworker when working on some issues/features, and Skype easily lets us do that. One of the best things about Skype is that the screen can be shared without being on a video/voice call - which is of immense advantage because oftentimes, you could prefer sharing the screen, while it [is] too noisy to talk.

  • 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
  • Probably the biggest area is the video element as it has historically struggled in this area.
  • The need to be forced to federate with another organisation by providing yours and enabling the other organisation settings is a bit tedious but once done, allows for simple collaboration between third-parties.
  • Functionality wise, as it's an older product and being superseded by MS Teams, it feels as if it's run its course but was very good for what it does/did at the time.

  • The only thing I can think of is that it is easy to create too many channels. This has more to do with the team using Slack and less to do with Slack itself. maybe some direction on Slack's part on how best to utilize channels would be helpful.

The software is simple to install and configure. It is rather simple to explain for correct use. It is possible to profile users for the different functions offered. It is integrated quite completely with Outlook and with Active Directory security. It performs all communication functions well with one or more interlocutors and the possibility of granting control of your computer is convenient.

As useful as Slack has become within our company, I feel fairly confident we will continue to use Slack as a communication tool.

Very easy to use. Even though Microsoft Teams has a lot of features and integrations, as a user I feel completely comfortable on finding what I need, getting information about the app extensions and using them. It's a very comprehensive tool, intuitive design and does not make me feel tired to be using it. I am glad with the current experience.

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.

I have only had to reach out to the Support team at Skype for Business once with an issue, and I was pleasantly surprised and encouraged by the quickness and thoroughness of their response.

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.

Skpe for business is utilized company wide in regards to my company. Everyone not only uses it, but uses it often. It is an effective way of communicating. It also integrates very nicely with outlook and all conversation history is pushed to a folder within the outlook system. We also have it so that if someone misses a message, they are sent an email reminder saying that there is a message that went unread.
