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.

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.

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.

There are 53 people using Slack in our organization.

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.

What do I think about the stability of the solution?

The stability is good. It doesn't matter how many people use it.

How was the initial setup?

Setup is pretty easy.

What other advice do I have?

I would rate this solution 8 out of 10. 

You can use it on your phone, not just on your PC or laptop. It pretty much works the same, and you can do almost everything on your phone.

Which deployment model are you using for this solution?

Valuable for announcements and communicating between team members
Pros and Cons
  • "It's valuable for announcements and communicating between team members."
  • "There could be a read function so that when you send a message, instead of the other person having to add a reaction, you know that the message went through."

What is our primary use case?

We use Slack for communication and announcements.

The solution is deployed on-premises. We have around 65 people using this solution in our company.

What is most valuable?

It's valuable for announcements and communicating between team members.

It also gives you the ability to have video calls and share your screen. 

What needs improvement?

There could be a read function so that when you send a message, instead of the other person having to add a reaction, you know that the message went through.

For how long have I used the solution?

I have been using Slack for roughly three and a half years.

What do I think about the stability of the solution?

It has not crashed once in three years, so I would say it's pretty good.

What do I think about the scalability of the solution?

The scalability is okay.

How are customer service and support?

We haven't had any issues, so we haven't needed to contact technical support.

How was the initial setup?

It's very simple. You just use your work email, sign in, and that's about it.

What other advice do I have?

I would rate this solution 8 out of 10.

My advice is to use both the mobile and desktop versions.

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 technical 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.

A clean and efficient communications platform that is good for large teams
Pros and Cons
  • "With respect to being a clean and efficient communications platform, I think that it does the job quite well."
  • "I have found it cumbersome to create and set up groups, or channels."

What is our primary use case?

I use Slack primarily for communications. This includes communicating with individuals as well as grouping people into cells to work on specific parts of a project. We don't use the features beyond just the basic communicative side of it.

What is most valuable?

With respect to being a clean and efficient communications platform, I think that it does the job quite well.

It's very good for when you have a large number of people working within the team. It can be a challenge to ensure that people are working within the bounds of the project that they are assigned to, and Slack is effective for ensuring that happens.

What needs improvement?

I have found it cumbersome to create and set up groups, or channels. I recall having to go through the application, then back to the web site, and then back to the application. I didn't really like that and this is something in the interface that should be improved. If it were possible or easier to create those working groups within the application, without being taken into a browser and working entirely within the software itself, that would be ideal.

I would like to see integration with collaborative tools, such as word processing software or programming environments and coding software, made clear, easy, and as broad as possible. It should handle simple products, all the way to complex ones. It should be easily embeddable inside a channel so that anyone can use it.

I think that changing the privileges to remove restrictions would help the users to adapt to the platform more easily, removing bottlenecks. Having to request access for particular users is time-consuming and it would be better if more people can do these things themselves.

For how long have I used the solution?

I have been using slack since the beginning of 2019.

What do I think about the stability of the solution?

I have not noticed any bugs, glitches, or other issues with stability.

What do I think about the scalability of the solution?

We have between 30 and 50 users.

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

A lot of the work that we're doing now ends up on Microsoft Teams. Whether I like it or not, it tends to marginalize and eventually push Slack out of the picture.

How was the initial setup?

I found the initial setup to be straightforward. You can also bombard people with reminder messages that they should be joining a channel or discussion. In fact, I've had less trouble with slack than I've had with Teams.

What other advice do I have?

From my perspective, this is a good product and I definitely recommend it. My advice for anybody who is implementing this type of product is to first consider what it is that they want to achieve, and then make the decision about which product to implement based on that. If you're trying to pick between platforms, like Teams versus Slack, I would recommend Slack for a variety of reasons. Even if you are using Teams already, I would suggest using Slack in addition because you can't go wrong.

I would rate this solution an eight out of ten.

Easy to use with an intuitive interface and the screen sharing works well
Pros and Cons
  • "The most valuable feature is the screen sharing, which works well."
  • "I would like the text in chat to be more customizable."

What is our primary use case?

We are using Slack for web conferencing. It is primarily for external communication with one of our suppliers.

What is most valuable?

The most valuable feature is the screen sharing, which works well.

This solution is freely available to almost everyone.

The tracking, integration tool, and voice calls are all good.

The user interface is intuitive for me.

What needs improvement?

There should be better integration between Slack and Office 365.

It should be easier to work collaboratively on files.

I would like the text in chat to be more customizable.

For how long have I used the solution?

I have been using Slack for a couple of months.

What do I think about the stability of the solution?

We have not experienced any problems with stability. We use it maybe once a week to contact one of our suppliers.

What do I think about the scalability of the solution?

As a user, I have not had problems with scalability. I am part of a small group that makes use of slack but that doesn't mean that it isn't widely used in the company.

How are customer service and technical support?

I have not been in contact with technical support.

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

We are using multiple web conferencing tools including Mircosoft Teams, Skype, and Slack.

I would say that the user interface in Slack is more intuitive than in Teams. One advantage to teams is that it is fully integrated into Office 365. I would say that collaborative working on files is better in teams. In our situation, the focus of Teams is internal, rather than with external partners.

What other advice do I have?

Overall, this is a good product and I can recommend it. It's easy to use and so far, it has been reliable.

I would rate this solution an eight out of ten.

Helps with basic communication but needs to improve stability
Pros and Cons
  • "Slack helps me to read bulk messages."
  • "The tool has stability issues that need to be improved. We are not native English speakers and Slack needs to integrate grammar checks."

What is our primary use case?

We use the solution for basic communication such as chatting. 

What is most valuable?

Slack helps me to read bulk messages. 

What needs improvement?

The tool has stability issues that need to be improved. We are not native English speakers and Slack needs to integrate grammar checks. 

For how long have I used the solution?

I have been working with the product for five to six years. 

What do I think about the scalability of the solution?

I would rate the product's scalability an eight out of ten. My company has 5000 users on Slack. 

How are customer service and support?

I haven't encountered any outages and hence never contacted the support. 

How was the initial setup?

Slack's setup is simple. 

What other advice do I have?

I would 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.
