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.

Enables communication with the developer community and has a very good portal
Pros and Cons
  • "The portal is at its best version now."
  • "Sometimes, the servers are not available."

What is our primary use case?

I use the solution to communicate with the developer community. If I have any issues, I reach out to them for troubleshooting. I also use the product to know about upcoming tool upgrades. We use the solution as a community to reach out.

How has it helped my organization?

We use Dependency Track. I had multiple issues during the configuration. I contact the tool developer using Slack to identify the issue. The developer provided me with a resolution, and the issue was resolved.

What is most valuable?

Sometimes, someone has already faced issues similar to what we are facing. Instead of asking the question again, we can search the question and look for the remediation that is already mentioned. The portal is at its best version now. There shouldn't be any changes. The solution provides two-factor authentication. The integrations are good.

What needs improvement?

Sometimes, the servers are not available. It is rare, but it happens.

For how long have I used the solution?

I have been using the solution for two years.

What do I think about the stability of the solution?

I rate the tool’s stability a ten out of ten.

What do I think about the scalability of the solution?

The tool is scalable. We have 20 users in our organization. Only some people in the organization do R&D work.

What other advice do I have?

Overall, I rate the product a ten out of ten.

Which deployment model are you using for this solution?

On-premises

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.

  • "The product is user-friendly."
  • "It is difficult to navigate the tool when I log in to two devices and start a video call."

What is our primary use case?

I use the solution for communicating with all the teams. We can communicate with people from other countries.

What is most valuable?

The product is user-friendly. It is easy to use. The colors, the menu, and the sidebar on the interface are good. Push notifications work well on mobile devices. It is what I need. It is helpful and useful for me. I am happy with the video calls.

What needs improvement?

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.

For how long have I used the solution?

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

What do I think about the stability of the solution?

The product is stable.

What do I think about the scalability of the solution?

A highly stable and affordable solution that can be used for team collaborations
Pros and Cons
  • "Tasks and team huddles are the most valuable features of Slack."
  • "It would be better if Slack had a 'select all' option to delete all the files."

What is our primary use case?

I use Slack for team collaboration.

What is most valuable?

Tasks and team huddles are the most valuable features of Slack.

What needs improvement?

When I share any file with my colleagues, that file remains in Slack storage even after I delete the message. I need to manually delete them one by one. It would be better if Slack had a 'select all' option to delete all the files.

For how long have I used the solution?

I have been using Slack for four years.

What do I think about the stability of the solution?

Slack is a stable solution.

I rate Slack ten out of ten for stability.

What do I think about the scalability of the solution?

Around 20 users are using Slack in our organization, and we have plans to increase the usage.

I rate Slack an eight out of ten for scalability.

How was the initial setup?

On a scale from one to ten, where one is difficult, and ten is easy, I rate Slack a seven out of ten for the ease of its initial setup.

What's my experience with pricing, setup cost, and licensing?

The solution’s pricing is cheap.

What other advice do I have?

I use Slack on the cloud as a SaaS service. I recommend Slack for better conversations in a product team.

Overall, I rate Slack a nine out of ten.

A collaboration tool where you can share files and to do a one-on-one or a group conversation
Pros and Cons
  • "Slack is a collaboration tool where you can create specific topic-related channels and manage different threads on different talks so people can interact and maintain a chat."
  • "When scaled on a large scale, the solution's cost becomes a matter of concern for organizations."

What is most valuable?

Slack is a collaboration tool where you can create specific topic-related channels and manage different threads on different talks so people can interact and maintain a chat. You can use the solution to share files and to do a one-on-one or a group conversation. It's a multilateral functional collaboration platform.

What needs improvement?

Slack is difficult to scale. When scaled on a large scale, the solution's cost becomes a matter of concern for organizations. It is a large project to migrate from Slack to Microsoft Teams or any other platform.

What do I think about the stability of the solution?

Slack is a pretty stable solution. I rate Slack an eight or nine out of ten for stability.

What do I think about the scalability of the solution?

Slack is a scalable solution, but not every organization can afford to maintain it. I rate Slack an eight out of ten for scalability.

How was the initial setup?

The solution’s initial setup is complex.

What other advice do I have?

It's up to the organization whether it wants to use Slack or not. Some people like the solution, while others don't.

Overall, I rate Slack eight out of ten.
