We primarily use it for sharing official documents and compositions instead of using platforms like WhatsApp. Although we haven't utilized it for meetings, the main purpose behind creating and using it is to streamline the sharing of official information within our team.

It is difficult to navigate the tool when I log in to two devices and start a video call. If I log in to two devices, I get logged out of video calls.

I have been using the solution for the last four months.

Product Development Manager at a tech services company with 11-50 employees
The product enables efficient communication and collaboration, but it crashes when used on the desktop
Pros and Cons
- "Slack provides very fast communication."
- "The product crashes when I use it on the desktop."
What is our primary use case?
We use the product in the office for communication. It's our main channel for any communication.
What is most valuable?
Slack provides very fast communication. The communication is sent directly to me, so I do not miss out on anything. The product provides various channels to communicate. A channel is like a team, where all communication regarding a team is sent. The product gives the flexibility of having many channels. Communication is isolated and sent to the right person at the right time. Slack has a voice messaging feature.
What needs improvement?
The product crashes when I use it on the desktop. The product must improve user experience. It would be quite interesting if Slack works with Microsoft Teams.
For how long have I used the solution?
I have been using the solution for six years.
What do I think about the stability of the solution?
The product crashes sometimes. I've never understood what the problem is. It happens intermittently. I don't know what really makes it crash, but it happens once in a very long time.
What do I think about the scalability of the solution?
The solution is scalable. We are a huge team. We’re about 40 people. All of us use it seamlessly. It achieves our objective as a small team.
Which solution did I use previously and why did I switch?
In 2006, we used IP Messenger. It worked the same way but could be used only in the office. We didn't have any visibility of the communication outside the office. It did not have channels. It had many drawbacks, and Slack solved a lot of those problems.
How was the initial setup?
The solution is quite easy to set up. Anyone can easily set up the product, whether senior employees, junior employees, or professionals.
What other advice do I have?
I use Slack on my desktop. I have it on my phone too. All communications reach me as soon as they are sent, whether I’m in the office or outside. I don't look at the product for improvement. I appreciate what the product is doing. I'm not an administrator. I am a typical user. I joined the Slack channel because I was invited. I have access to Slack as a user, not as an administrator. I used IP Messenger as a software developer for a medium-sized organization in Kenya. We could share files. We could send text messages and all of it. We couldn’t use IP Messenger outside the office. It did not have channels.
For people who need constant communication and don’t want to rely on emails, Slack is the right tool for them. We can work on the mobile phone to communicate on the go. As long as we have internet connectivity, it is secure. We can create as many channels as we like and collaborate. We can also do voice calls and send voice notes. Overall, I rate the product a seven out of ten.

Has a great user interface and functionalities and helps with remote communication

- "The solution needs to improve its scalability."
What is our primary use case?
I use the tool to communicate with my team because we work remotely since COVID.
What is most valuable?
The solution has a great user interface and functionalities. It has good features that we can use. We can integrate any third-party application with Slack so that it provides you with insights and updates in real-time on Slack itself.
What needs improvement?
The solution needs to improve its scalability.

What do I think about the stability of the solution?
I would rate the product's stability a ten out of ten.
What do I think about the scalability of the solution?
I would rate the solution's scalability a nine out of ten. My company has 60 users for the product.
How was the initial setup?

What was our ROI?
The product is worth its money.
What's my experience with pricing, setup cost, and licensing?
The solution is expensive.
What other advice do I have?

Dealer at a financial services firm with 11-50 employees
Great for communication, easy to implement, and can expand as needed
Pros and Cons
- "The product has the ability to scale."
- "We’d like it to have more capability for everyone to work on one doc in real time all at once."
What is our primary use case?
We're using Slack to communicate with other partners outside of our company. In most of the cases, it's for external communication.
What is most valuable?
Basically, it’s great for getting different kinds of groups with different partners - let's say one with the IT, one with the payment solution, into one place. It’s used just to communicate and nothing more than that. It's just a better solution to use instead of Skype or any other standard application.
It is easy to set up.
The solution is stable.
The product has the ability to scale.
What needs improvement?
The last time I tried to work with some other partners on the same document, we couldn't figure out a way to work on the same one. We actually have to have one person gather all the documents and then prepare one. It was actually taking way much longer than usual. We’d like it to have more capability for everyone to work on one doc in real time all at once.
For how long have I used the solution?
I’ve been using Slack for three or four years.
What do I think about the stability of the solution?
The solution is very stable. It doesn’t have bugs or glitches. It doesn’t crash or freeze. It’s reliable.
What do I think about the scalability of the solution?
I haven’t seen a lack of scalability. It seems like it would be easy to expand.
Most of our colleagues use the solution. We have around 100 people on the solution.
How are customer service and support?
I haven’t used technical support. I can’t speak to how helpful or responsive they are.
Which solution did I use previously and why did I switch?
We’ve also used Skype.
How was the initial setup?
It's easy to set up. The IT team didn’t take that long to install it. There’s nothing wrong with that.
What's my experience with pricing, setup cost, and licensing?
I don’t deal with the licensing aspect of the solution.
What other advice do I have?
I'm not sure about the version I'm using. IT is taking responsibility for that.
I’d recommend the solution. It's easy to use. You just kind of need to use it more often just to get used to it and see how it works. It's nothing hard to figure out. It's easy to start.
I’d rate the solution an eight out of ten.

Associate Vice President at a tech services company with 11-50 employees
A secure and widely-used solution that integrates easily and is helpful for internal and external communication
Pros and Cons
- "You can create channels between teams internally and externally, which is great. There is a lot of security with Slack internal, which is what I value."
- "I would like to be able to do live streaming on Slack. Slack allows Slack huddle where you can do a group call, but it is not very well-designed. I'm not sure if it is going very well, but live streaming is one thing that I would definitely love to see. When you use Zoom, I like how you can run webinars. If we could do that through Slack, it would become an all-integrated platform. I would also like to be able to schedule meetings using Slack, similar to Zoom."
What is our primary use case?
We use it for internal communication, and we also use it for external communication or customer relations.
What is most valuable?
You can create channels between teams internally and externally, which is great. There is a lot of security with Slack internal, which is what I value.
You can very easily share large files through Slack. Integration is easy.
What needs improvement?
Their notifications are generally not very prompt. There is a problem with their notification engine, and sometimes, I end up pressing on notifications. There are a few bugs there.
It also tends to lag sometimes. It gets slow.
I would like to be able to do live streaming on Slack. Slack allows Slack huddle where you can do a group call, but it is not very well-designed. I'm not sure if it is going very well, but live streaming is one thing that I would definitely love to see. When you use Zoom, I like how you can run webinars. If we could do that through Slack, it would become an all-integrated platform. I would also like to be able to schedule meetings using Slack, similar to Zoom.
I would like to see better connectivity between Slack and Gmail where Slack can prompt me for some of the things from my Gmail. For example, there can be a prompt such as "This person has been mailed, and you can contact him through Slack."
It should have an automated translator. It would be helpful for interacting with people who are multilingual. For example, I speak English, but the other person might not understand English. There should be an automated translator inbuilt into Slack for such situations. Instagram has a similar feature where for a caption, you can click the See Translation button, and it does the translation for you. This is something that Slack could add.
For how long have I used the solution?
I have been using this solution for almost 18 months.
What do I think about the stability of the solution?
It is fairly stable.
What do I think about the scalability of the solution?
It can be scaled very easily. We have about 20 people who use this solution.
How are customer service and support?
I have not used their support so far.
How was the initial setup?
It was straightforward. It took one day.
What other advice do I have?
It is good. It is one of the best ones out there. You can definitely go for it.
When you're partnering with teams outside your organization, you can't really do without Slack. It becomes a necessity. We chose this solution because Slack was the most widely used solution. A lot of companies that we partner with and a lot of our customers end up using Slack. So, for us to partner with them, we needed Slack.
I would rate it a nine out of ten. It is widely used, but they need to work on its features.
Which deployment model are you using for this solution?

Allows you to create different channels, have conference calls, and share your screen
Pros and Cons
- "We use Slack for general communication, conference calls, and sharing screens because we have people working from different countries."
- "I think Slack could add additional features without making the solution slower or more difficult to use."
What is our primary use case?
We use Slack for general communication, conference calls, and sharing screens because we have people working from different countries.

The solution is deployed on-premises.
What is most valuable?
It gives you the ability to share your screen and have conference calls. You can also create different channels. You can use it on your PC or on your phone.
We recently had to learn about another program, and somebody had to teach from abroad. They could share their screen, and we were able to have a conference call through that.
What needs improvement?
Everything has room for improvement, so I think Slack could add additional features without making the solution slower or more difficult to use.
For how long have I used the solution?
I have been using this solution for a year and a half.
