The tool helped us with collaboration. Another use case for us was ticketing, where people who needed to take action could be informed immediately on Slack rather than over the conventional mechanism of emails. You need to look over hundreds of emails and then realize that there is a ticket. You can also collaborate to get document reviews done and avail feedback immediately rather than exchanging and putting it in our systems.

Solution Consultant at a tech vendor with 501-1,000 employees
A perfectly scalable tool that is easy to use and enables organizations to stay in contact with partners and create workspaces
Pros and Cons
- "The product is easy to use."
- "The integration with SharePoint doesn’t work properly."
What is our primary use case?
I use the solution mainly for chat. I go on spontaneous calls with colleagues. We also have channels for specific topics or customers and share workspaces with partners. Some of our partners also use Slack. So, we use shared workspaces and channels, which is a very good way to stay in contact with them.
What is most valuable?
The product is easy to use. It provides an easy way to stay in contact with partners and create workspaces. We can exchange information, have discussions, and search for information. We create channels for technical topics. It is quite useful to find answers because others in the team might have the answers to our questions.
What needs improvement?
The integration with SharePoint doesn’t work properly. It might be due to an access issue in the company. It is quite annoying. Sometimes, we cannot copy a shared document, but it might be because of the settings.
For how long have I used the solution?
I have been using the solution for four years.
What do I think about the stability of the solution?
The tool is super stable.
What do I think about the scalability of the solution?
The tool is perfectly scalable. The whole company uses it. We have around 1000 users. My colleagues at IBM have an even larger installation that works quite well.
Which solution did I use previously and why did I switch?
Our organization has multiple tools, like Microsoft Teams, Zoom, and Webex. I can choose the one I like. I chose Slack because it is easy to use, and the spontaneous communications and channels are very useful. I prefer Slack for chats, channels, and exchanges with partners, but I prefer Teams or Zoom for web meetings, training, and webinars.
How was the initial setup?
The product is easy to set up. The solution is deployed on the cloud.
What other advice do I have?
I recommend people to start using the solution. And make sure you use the status feature and synchronize it with Outlook, so that people can see when you are busy. Overall, I rate the tool a ten out of ten.

Enhancing team communication and collaboration through organized channels, real-time messaging, seamless file sharing, and versatile third-party integrations
Pros and Cons
- "It allows to facilitate communication, allowing us to create channels for updates, file sharing, and photo sharing within our team profiles."
- "Integrating Slack with calendar functions would be advantageous, allowing for the seamless scheduling of meetings within the platform."
What is our primary use case?
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.
What is most valuable?
It allows to facilitate communication, allowing us to create channels for updates, file sharing, and photo sharing within our team profiles.
What needs improvement?
Integrating Slack with calendar functions would be advantageous, allowing for the seamless scheduling of meetings within the platform.
For how long have I used the solution?
I have been using it for two months now.
What do I think about the stability of the solution?
I would rate the stability eight out of ten.
What do I think about the scalability of the solution?
Its scalability is evident in its ability to handle a varying number of users, channels, and integrations, making it suitable for businesses of different sizes and complexities. I would rate it eight out of ten.
Which solution did I use previously and why did I switch?
We previously employed Google Workspace. Slack provides visibility into the online status of team members when the application is active, it doesn't track users outside of the platform. Unlike some other tools, such as Gmail, where your online status isn't visible to others when you're using it, Slack primarily serves as a communication and collaboration platform.
What other advice do I have?
Overall, I would rate it eight out of ten.

What is our primary use case?
I use the solution for communicating with all the teams. We can communicate with people from other countries.

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

The product is stable.
What do I think about the scalability of the solution?

Disclosure: My company does not have a business relationship with this vendor other than being a customer.
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.

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.
