We're using Slack to communicate with other partners outside of our company. In most of the cases, it's for external communication.
Dealer at Invaxa
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?
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.

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.

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.

I don’t deal with the licensing aspect of the solution.

I'm not sure about the version I'm using. IT is taking responsibility for that.

Pros and Cons
- "The portal is at its best version now."

The portal is at its best version now. There shouldn't be any changes. The solution provides two-factor authentication. The integrations are good.

Solution Consultant at Apptio
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.

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?

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

Pros and Cons

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?

How has it helped my organization?
The product makes communication seamless. There are around 200 employees in my organization. If the HR personnel want to reach us, they use the channels to put up messages, posters, and banners for workplace events or blood donation drives. They use the channels whenever they want to spread information about anything.
What is most valuable?
Slack is a really good solution. We can see whether our colleagues are available or away. If we need to share any information within our team, we can create a channel and share the information. We can share technical and non-technical information like, HR information using the product. Information sharing is the feature I like the most. The product allows us to update our status to communicate whether we are away or out for lunch. We can also make notes to ourselves using the solution. It functions quite well.

The UI could be a little bit better.

Senior Director - Data Management at a tech services company with 1,001-5,000 employees
A collaborative tool that helps teams across different locations to have a common workspace
Pros and Cons
- "I am impressed with the product's calls and screen share features which are very useful."
- "I want a feature in the solution that will help me share documents only with the set of people that I prefer rather than all of them. I would also like the solution to have a feature similar to Microsoft SharePoint where you can group all your documents."
What is our primary use case?
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.
What is most valuable?
I am impressed with the product's calls and screen share features which are very useful.
What needs improvement?
I want a feature in the solution that will help me share documents only with the set of people that I prefer rather than all of them. I would also like the solution to have a feature similar to Microsoft SharePoint where you can group all your documents.
For how long have I used the solution?
I have been working with the product for one year.
What do I think about the stability of the solution?
I haven't encountered any issues with stability.

We use the solution's cloud version.
What other advice do I have?
I would rate the product a nine out of ten. The tool is a great collaborative tool that works well with teams spread across different locations. It helps them to come together and have a common workspace to work efficiently. Slack is a productivity improvement tool as well. My company has migrated to Teams since we subscribed to the Office 365 suite and switched to a standard communication channel.
