Overall Satisfaction with Slack

We use Slack for both company-wide communications and employee-to-employee interactions. We can have small, lightweight chats without the slowdown of email or meetings on specific topics, and also share company-wide communications quickly. As a remote organization, this is vital for us.

Pros

  • Enable light weight fast real time communications.
  • Organized Slack groups (such as departments, teams, project-based, or ERGs) to consolidate messaging when needed.
  • Culture - create informal watercooler chats, partner with outside integrations to put in, for example, a different topic or question per week to bring forward more conversation.

Cons

  • Sometimes key information can get buried in busy channels, even if you pin it. I'm not sure how this could be fixed.
  • It would be beneficial to adjust settings to prevent overwhelming people with notifications across all channels. I'm unsure how to strike a balance between ensuring people don't miss important notifications and not being overwhelmed with non-essential ones. Perhaps implementing the ability to categorize messages by urgency level could help?
  • Very expensive, would be nice to have a scaling cost for smaller orgs that could benefit.
  • We are able to get information to people faster so they are able to pivot as needed on important business objectives.
  • People are able to work together/collaborate more easily since they can get in contact more easily and create project-based Slack channels.
  • Culture-wise, we are able to bring folks together and make them more company/mission-oriented.
Slack is very easy to use. You simply type a person's name in and send them a message. I have had non users and older, not as tech friendly users use slack and be able to use it without any introduction of training necessary. It's a great tool for any and everybody. (It would be nice to have an automatic language translator for non native language speakers using the app).

Do you think Slack delivers good value for the price?

Yes

Are you happy with Slack's feature set?

Yes

Did Slack live up to sales and marketing promises?

Yes

Did implementation of Slack go as expected?

Yes

Would you buy Slack again?

Yes

Slack is especially good for small to large organizations that are remote. But I think Slack is really ideal for any organization that needs to get communications across quickly and efficiently. It might not be as good for extra-large companies that would benefit from a homegrown system that is specifically suited to their needs.
