Product version discussed: 4.42.120
Threads and documentation elevate collaborative release management

Pros

"In managing releases via Slack channels, one major advantage over Teams is the ability to have threaded discussions, which helps in catching up on relevant discussions without the distraction of interleaved conversations."

Cons

"Slack's channel and chat management could be more intuitive."

Enables engaging communication with interactive features but requires improvements in reliability and meeting functionalities

Pros

"The integration with Google Calendar is easy to use and allows us to receive notifications before meetings."

Cons

"Sometimes Slack behaves unexpectedly and shuts down without notification or support communication."

A competitive solution that improves collaboration and productivity

Pros

" When we work with a platform like Slack, we can have one source without merging different document versions."

Cons

"Slack is not as strong as competitors like Teams when it comes to things like video meetings and audio meetings."

Used for internal communication within the company

Pros

"The most valuable features of Slack are basic chatting, file sharing, and screen sharing."

Cons

"Slack's screen sharing might also add the remote control feature, which is not there."

Creates customizable applications while improving accessibility features

Pros

"Slack offers the ability to make customizable applications and plugins."

Cons

"In Slack, there are areas for accessibility improvements. "

A collaborative tool that helps to manage daily activities

Pros

"Nowadays, we don't need to visit an HR portal. Our marketing and human resources teams directly share details about birthdays, upcoming events, and important dates in Slack. Whether it's a training event, a company-wide gathering, or a social event, all the information is shared there. This keeps us all updated. "

Cons

"We could see improvement in Slack by having an integrated meeting tool. Currently, we rely on third-party integration tools like Zoom to schedule meetings. It would be much more convenient to schedule meetings directly within Slack without additional integrations. It needs to have calendar and CRM integrations as well. "

Provides a more convenient and efficient alternative to email, especially for internal conversations and coordination

Pros

" Slack helps us keep the conversation focused and avoid multiple threads that create more confusion. I would say that has been the biggest advantage for us."

Cons

"For me, the only thing I can say is that every time somebody sent me an attachment, the attachment was listed somewhere, and then I had to open the conversation and go to the individual to open it. So there is no handy repository or an easy way to quickly look at attachments. For me, that was a bit difficult."
