Good communication features help to promote collaboration between team members
Pros and Cons
  • "The feature that I have found most valuable is communication between team members."
  • "Customization is something that Slack is lacking."

What is our primary use case?

Our internal team primarily used Slack for communication with each other. If two or three people were working on the same modules then they were able to share code and work together.

What is most valuable?

The feature that I have found most valuable is communication between team members.

What needs improvement?

Customization is something that Slack is lacking. Otherwise, however, the user interface is very good.

For how long have I used the solution?

We have been using slack for the past one and a half years.

What do I think about the stability of the solution?

Recalled that there were some bugs about a year ago. However, I don't recall the details or what they did to rectify the problem.

How are customer service and support?

I have not personally been in contact with technical support. When we experienced the bugs about a year ago, my team may have been in contact with them. Ultimately, the problem was resolved.

Which solution did I use previously and why did I switch?

We primarily use Slack and Microsoft Teams. We know of Confluence but do not use it much.

Slack is a better product than Teams. Teams is more like a chat window, rather than a development window. We were also having issues with Teams, initially, with the user interface when we were trying to create groups. We found that it was not that easy, or perhaps not convenient.

What other advice do I have?

My company has been acquired so we are going to align our systems with our parent company. At this point, I am not sure if we will continue with Slack or instead move to another solution. I have suggested that we continue using the same tools, but at this point, I am not sure.

In my opinion, this is a good product and I recommend it. Slack is much better than Microsoft Teams.

I would rate this solution an eight out of ten.

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.

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.

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.

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

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.

A scalable and easy-to-deploy solution that enables seamless communication within the organization
Pros and Cons
  • "The product makes communication seamless."
  • "The UI could be a little bit better."

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.

What needs improvement?

The UI could be a little bit better.

For how long have I used the solution?

I have been using the solution consistently for the last year.

What do I think about the stability of the solution?

The tool is stable. Many employees in the organization are happy to use the product.

What do I think about the scalability of the solution?

The solution is scalable. As more and more people join the organization, they are able to use the tool.

How was the initial setup?

The initial setup was easy. The solution is deployed on the cloud.

What other advice do I have?

I work from home. I do not use the on-premises product. If people use it consistently, they will understand how to use it and communicate with their teams properly. Overall, I rate the solution an eight out of ten.

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. 

What do I think about the scalability of the solution?

The solution is scalable and can accommodate thousands of users. I didn't see any problem with scaling. My company has 1500 users for the product. 

How was the initial setup?

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.

A good solution for communication and file sharing, but it should add a feature to schedule meetings
Pros and Cons
  • "The huddle feature that allows you to get on a call with a colleague is one of the best features of Slack."
  • "Slack should add a feature to schedule meetings."

What is our primary use case?

We use Slack for communication, file sharing, meetings, text messages, etc. Slack has been so helpful for us.

How has it helped my organization?

Slack has made communication much easier in our company. I can text someone in the company or send a message. I can also have an audio call with a couple of team members on the go without needing to start setting up calls on Zoom or Google Meet, or Microsoft Teams. I can have that voice or video call right away on Slack.

What is most valuable?

The huddle feature that allows you to get on a call with a colleague is one of the best features of Slack. You can call someone on the go with the huddle feature and save the time of having to set up Zoom calls or Google Meet.

What needs improvement?

Slack should add a feature to schedule meetings. Users should get notifications or prompts regarding the meeting time so they can attend that meeting.

Sometimes, when Slack is down, there is a delay in messages being delivered. Such delays also need to be improved in Slack.

For how long have I used the solution?

I have been using Slack for the past five years.

What do I think about the stability of the solution?

I rate Slack a six out of ten for stability.

What do I think about the scalability of the solution?

I rate Slack a seven out of ten for scalability.

How was the initial setup?

Slack’s initial setup was not difficult.

What other advice do I have?

I use the latest version of Slack. Slack is deployed on-cloud in our organization.

I highly recommend Slack for teams that want to communicate and collaborate. Slack can integrate with other apps like Google Calendar and Loom for voice and video recording. I recommend Slack for teams that want to scale and collaborate.

Overall, I rate Slack a seven out of ten.
