Overall Satisfaction with Slack

Colleague communication.

Pros

  • Direct communication with teams, group chats and channel to bring people and subjects together.

Cons

  • Limitations on group chats where it's only limited to nine people and then you have to make it into a channel, which is pretty frustrating because you can't remove people out of a group, which is boggling. Drives me nuts.
  • Positive because it keeps us connected.
Because 10s shouldn’t be given out easily. It’s not quite there — there are some flaws, like connection issues or doesn't send something. I wouldn’t call it a standout feature, so 10s shouldn’t be handed out so easily.
From a corporate standpoint, I don’t really have another example. On a personal level, the closest comparisons would be WhatsApp, Messenger, or KakaoTalk. To me, it feels like — as I said — the corporate WhatsApp. Not that Salesforce wants it to be compared that way or used standalone, but personally, I don’t associate Slack with personal use.

Do you think Slack delivers good value for the price?

Not sure

Yes

Did Slack live up to sales and marketing promises?

I wasn't involved with the selection/purchase process

Did implementation of Slack go as expected?

I wasn't involved with the implementation phase

Would you buy Slack again?

Yes

Colleague communication — that’s what we use it for the most. I think other teams might use it in other ways, but for me, it’s like the WhatsApp of the Salesforce world when it comes to corporate communication. As for where it’s less appropriate, I honestly don’t have an example off the top of my head. It doesn’t replace in-person connectivity, but for remote workers, it’s a necessity.
