Overall Satisfaction with Slack
Slack has become our primary source of communication within our organization. Whether it is quick communication, scheduling projects or discussing key work it is the primary surface area our remote team goes to get work done. In addition to communication, it becomes a key place to find relevant information (including documents and past decisions).
Pros
- Organizes communication at high volume (large teams)
- Makes it easy to have real time discussions
- Integrates with a large suite of tools to help connect work (like Jira/Figma) or automate work flows (forms and checkins)
Cons
- Slack with video integration - While its easy to start Zoom, I would love to see integration from chat in a call into threads in Slack
- DMs to channels are a little rigid. It would be great to have a more fluid way for DMs (private messages) turn into channels to be more inclusive.
- Notification permissions have gotten much better, but having more granular notification control by channel would help reduce noise
- The DM UX is being pushed heavily - I personally feel the homescreen organization is much easier to navigate (wish I had control to say more in this view vs the new state).
- Improved the quality of our delivery (avoiding costly issues)
- Improved team culture - empowering people to work better together and find commonalities
- Helped us win new business (live communication on pitches and new biz discussions)
Slack has much better UI and search compared to Teams. Teams is much better as an integration into the Microsoft suite (if you use Teams for meetings or Office for email, it might be a better solution for your org).
Teams feature set might be comparable but it is difficult to fully understand and intuit the features available to use (doc sharing, wiki etc appear to be integrated but are confusing to use).
