What is our primary use case?
Slack is our main source of collaboration and we use it for all internal messages.
What needs improvement?
The way groups are created on slack could be improved. Once you create a group of people, you can't add additional people unless you convert it to a channel.
For how long have I used the solution?
I have used Slack for one year.
What do I think about the stability of the solution?
This is a stable solution.
What do I think about the scalability of the solution?
This is a scalable solution.
How was the initial setup?

Analyst at a government with 5,001-10,000 employees
Easy to use and supports multiple chat channels
Pros and Cons
- "The most valuable feature for me was the different channels."
- "Slack does not have videoconferencing capabilities, which would have been nice."
What is our primary use case?
We used Slack for all of our internal communications during the COVID pandemic.
What is most valuable?
The most valuable feature for me was the different channels. You can make categories and then jump between different channels and groups.
It is really easy to use.
What needs improvement?
Slack does not have videoconferencing capabilities, which would have been nice. It would be helpful if they added this feature in the future.
The addition of more chat features such as sending GIFs and emoticons would be an improvement.
For how long have I used the solution?
We were using Slack for about three months.
What do I think about the stability of the solution?
The stability is good. It had never failed us.
What do I think about the scalability of the solution?
It is widely used in our organization, although I cannot say how many users in total. In our department, there are 14,000 employees.
Which solution did I use previously and why did I switch?
We were using Slack and then during the COVID pandemic, we switched to Zoom. Now, we have installed Microsoft Teams and are working with it.
I think it would be excellent if they combined Slack and Zoom.
How was the initial setup?
The initial setup is easy. I had set something up wrong because I didn't make it private versus public, although I had not read anything about configuring it beforehand.
What's my experience with pricing, setup cost, and licensing?
My understanding is that we were using the free version.
What other advice do I have?
My advice for anybody who is considering Slack is that it is a great tool. For us, it's difficult to talk with other departments, so this was the ideal solution. Overall, we really liked it, although it would have been nice to have videoconferencing support.
I would rate this solution a ten out of ten.

Project Manager - Business Consultant at Comtrade System Integration
An easy to use, cost-effective collaboration tool with all the functionality that we need
Pros and Cons
- "Slack makes it easy for employees to contact each other and exchange documents or information."
- "I would like to see a special feature for multiple people to collaborate on a document, working on it at the same time."
What is our primary use case?
We are using Slack to collaborate between employees, as many of them are working from home. While I personally started using it a couple of years ago, it has been about a month since all of our employees began using it.
How has it helped my organization?
Slack allows our employees to share information on a daily basis without overloading email.
What is most valuable?
This solution is easy to use.
Slack makes it easy for employees to contact each other and exchange documents or information. It is not like a big CRM but for internal usage, it's good enough.
What needs improvement?
I would like to see a special feature for multiple people to collaborate on a document, working on it at the same time.
For most add-ons, clients need to know the command to run the add-ons. I think it would be useful for them to design the appropriate icons so that non-IT clients can launch them in a simple and easy way. For example, starting a video conference with an already defined room.
It would be useful for an organization to be able to define a specific storage space for the storage of all documents exchanged by teams
For how long have I used the solution?
I have been using Slack for two years.
What do I think about the stability of the solution?
This is a stable solution.
What do I think about the scalability of the solution?
We are only using the free version so I do not really know about the scalability.
We have 300 users and daily, there are 60% to 70% of them using it.
How are customer service and technical support?
I have not needed to contact technical support.
How was the initial setup?
Slack is very easy to set up and there are only a few steps involved.
What about the implementation team?
We deployed this solution ourselves. It was easy to send employees invitations to join.
What's my experience with pricing, setup cost, and licensing?
We use the free version that does not have a license.
Which other solutions did I evaluate?
We may use Microsoft teams in place of Slack in the future, although this is not a decision that I will be part of. At this time, there is not much interest in moving to Zoom or Teams.
We did not want to spend too much time investigating options before starting our remote work and because I was familiar with Slack, this is what I chose.
What other advice do I have?
My advice for anybody who is researching Slack is that it is easy to set up and quite helpful for daily common things. We use only the free license but it is enough for us. If we continue to use Slack after the current crisis ends then we may buy more features and add-ons. For now, however, we have what we need.
Overall, we are satisfied with Slack.
I would rate this solution an eight out of ten.
Which deployment model are you using for this solution?
Public Cloud

A stable platform for video conferencing, but in-meeting content sharing need to be improved

- "I would like the in-meeting content sharing facility to be improved."
What is our primary use case?
We use Slack for having meetings with one of our vendors.
What is most valuable?
The most valuable features are video conferencing and sharing content during meetings.

Slack is stable and we haven't had any problems.
What do I think about the scalability of the solution?
We have not had issues with scalability but our audiences in the meetings have not been large.
How are customer service and technical support?
The technical support is fine.
Which solution did I use previously and why did I switch?
In addition to Slack, we use Microsoft Teams as well as Skype. I think that all of these products are comparable, with nothing, in particular, that is an advantage or disadvantage.
What other advice do I have?
Overall, Slack meets the needs that we have.
I would rate this solution as average, at five out of ten.

Tech blogger at Blogospedia
Good content management with named channel capability to focus projects
Pros and Cons
- "Slack is a powerpack bundle of features that help small or large organizations to handle teams and their tasks."
- "I would like to see the social sharing of blogs, announcements, or other news directly from the message corner."
What is our primary use case?
I use Slack to communicate mainly for content related tasks with clients as they find it easy and quick to keep track of all of the on-going projects. Most importantly, it helped me to communicate with other content writers whenever I have to work in a team for a particular content project.
How has it helped my organization?
Earlier, while we used to communicate through email, it was good but it became difficult to keep track of all the projects and keep ourselves updated with the latest changes. Since we started using Slack, we have been able to solve each other's problems and identify all of the loopholes within a reasonable timeline.
What is most valuable?
Slack is a powerpack bundle of features that help small or large organizations to handle teams and their tasks. Personally, I love the feature that gives you the ability to name a channel as per task and include/exclude members within that channel to eradicate all other disturbances.
What needs improvement?
According to my observation, a large size file sharing feature is what can be expected, which will centralize all activities within Slack and that can save a lot of time.
I would like to see the social sharing of blogs, announcements, or other news directly from the message corner.
For how long have I used the solution?
I have been using this solution for three years.

It's our organization's chatroom where workflows and information are passed. We use Slack for communication within teams.
How has it helped my organization?
Slack has been very useful in our organization for doing communications and passing on pieces of information.
What is most valuable?
I really liked the Slack bot and its integration with partners to make the work easy and with proper flow. We can create a group also.
What needs improvement?
- I think it's the best till now and the Slack team is doing well.
- It will be great if they can start using the offline mode chat. Once we are back online, it will float the messages again.
For how long have I used the solution?
One to three years.
What do I think about the stability of the solution?
The product is stable, but you need an online connection.
What do I think about the scalability of the solution?
This product has been doing well until now.

You can have a free trial also for Slack, and its pricing depends on the features and team size you want to go with. The pricing is good, and it's worth it.
Which other solutions did I evaluate?
We were planning for Skype, Discord and Microsoft Teams.
