Slack Overview
What is Slack?

Slack is the top choice for teams to communicate. It provides a virtual workspace that helps teams maintain open communication in a business environment. With Slack, users can host voice and video calls with up to 15 participants and even screen share with a desktop app, empowering better user interaction. Slack also supports options for private and group sessions, and one of its best features is Slack Huddles–an informal meeting space that lets you directly talk to your channel where you can share screen side by side with your team. The platform integrates well with Dropbox, Google Drive, and Trello as well.

"Easy and fast to communicate with colleagues to discuss different tasks and projects."
What do you like best about Slack?

Huddle, it's fast and easy to just call the colleagues, no need to add personal social media or create Teams/Zoom meeting links.

What do you dislike about Slack?

Pictures in the conversation can not be replied on threads, so sometimes will be hard to select certain images. Will be very nice to add .gif function, to create more reaction within the company.

What problems is Slack solving and how is that benefiting you?

Communicate with colleagues who's out of the country or working remotely, it's easy to text or call.

"Slack @mentions and #channels change the way we manage our teams"
What do you like best about Slack?

Why do we love Slack's @mentions and #channels? Their ability to streamline the daily or real-time information flow. By using #channels as dedicated spaces for different topics, projects, or departments, we were able to centralize and ORGANIZE a framework where team members can collaborate, share updates, and discuss ideas. #channels facilitate real-time discussions, eliminating the need for lengthy email chains or scattered conversations across various platforms. This increment in transparency, knowledge sharing, and cross-functional collaboration in our company.

What do you dislike about Slack?

Huddle, slack built-in stand-up meeting tool is great to have audio meetings; but it's kind of glitchy when you use video or share your screen. If they improve that feature I think I probably get rid of Zoom!

What problems is Slack solving and how is that benefiting you?

By using Slack we improved communication and gain a stronger sense of cohesion within our teams. Slack has genuinely revolutionized the way we work, making it an invaluable tool for our agile teams by boosting team dynamics.

"Slack Review"
What do you like best about Slack?

Communication made easy. People from the organization can leave comments and status that helps us to determine what tasks were they on or their schedule. Created channels helps with faster communication via large size of receipients and pinned notes can be done too, topics and description can also be placed which is helpful to the users since they can differentiate on where they should be sending their message.

What do you dislike about Slack?

None. Slack helps us with daily tasks and easy communication. Highly recommended.

What problems is Slack solving and how is that benefiting you?

Communication can be challenging. Slack helps us determine the correct channels to reach out to and can easily check the status of the person we are trying to communicate from. Mentions between conversation can be easily seen that helps us respond timely

"Centralized and effective communication"
What do you like best about Slack?

What I like the most is the fact that it allows me to have both private and individual conversations, while at the same time, we have various channels where we can communicate as a team effectively and clearly.

What do you dislike about Slack?

The point that leaves something to be desired, in my opinion, is that sometimes the user experience gets a bit overwhelmed with the amount of messages, notifications, and events that happen in the Slack environment.

What problems is Slack solving and how is that benefiting you?

Being the primary point of contact for my company currently, within our environment, we have channels for the entire company, channels for inter-team communication, channels to receive notifications and stay updated on our product's status, we receive customer feedback, and in addition to that, we get daily notifications from our agenda.

"Primary Communication Platform"
What do you like best about Slack?

Very easy tool to use, and the functionality and ease of integration with other platforms is amazing.

What do you dislike about Slack?

I think like all communication platforms, it can become a bit messy with numerous channels, and lots of information being shared. This may be counterproductive.

What problems is Slack solving and how is that benefiting you?

Easy communication, quick messaging option, use it for internal phone calls or huddles and so much more.
