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.

An easy to use, cost-effective collaboration tool with all the functionality that we need

Pros and Cons

  • "Slack makes it easy for employees to contact each other and exchange documents or information."
  • "I would like to see a special feature for multiple people to collaborate on a document, working on it at the same time."

What is our primary use case?

We are using Slack to collaborate between employees, as many of them are working from home. While I personally started using it a couple of years ago, it has been about a month since all of our employees began using it.

How has it helped my organization?

Slack allows our employees to share information on a daily basis without overloading email.

What is most valuable?

This solution is easy to use.

Slack makes it easy for employees to contact each other and exchange documents or information. It is not like a big CRM but for internal usage, it's good enough.

What needs improvement?

I would like to see a special feature for multiple people to collaborate on a document, working on it at the same time.

For most add-ons, clients need to know the command to run the add-ons. I think it would be useful for them to design the appropriate icons so that non-IT clients can launch them in a simple and easy way. For example, starting a video conference with an already defined room.

It would be useful for an organization to be able to define a specific storage space for the storage of all documents exchanged by teams

For how long have I used the solution?

I have been using Slack for two years.

What do I think about the stability of the solution?

This is a stable solution.

What do I think about the scalability of the solution?

We are only using the free version so I do not really know about the scalability.

We have 300 users and daily, there are 60% to 70% of them using it.

How are customer service and technical support?

I have not needed to contact technical support.

How was the initial setup?

Slack is very easy to set up and there are only a few steps involved.

What about the implementation team?

We deployed this solution ourselves. It was easy to send employees invitations to join.

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

We use the free version that does not have a license.

Which other solutions did I evaluate?

We may use Microsoft teams in place of Slack in the future, although this is not a decision that I will be part of. At this time, there is not much interest in moving to Zoom or Teams.

We did not want to spend too much time investigating options before starting our remote work and because I was familiar with Slack, this is what I chose.

What other advice do I have?

My advice for anybody who is researching Slack is that it is easy to set up and quite helpful for daily common things. We use only the free license but it is enough for us. If we continue to use Slack after the current crisis ends then we may buy more features and add-ons. For now, however, we have what we need.

Overall, we are satisfied with Slack.

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.

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.

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.
