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 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.

Which deployment model are you using for this solution?

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.

The product enables efficient communication and collaboration, but it crashes when used on the desktop
Pros and Cons
  • "Slack provides very fast communication."
  • "The product crashes when I use it on the desktop."

What is our primary use case?

We use the product in the office for communication. It's our main channel for any communication.

What is most valuable?

Slack provides very fast communication. The communication is sent directly to me, so I do not miss out on anything. The product provides various channels to communicate. A channel is like a team, where all communication regarding a team is sent. The product gives the flexibility of having many channels. Communication is isolated and sent to the right person at the right time. Slack has a voice messaging feature.

What needs improvement?

The product crashes when I use it on the desktop. The product must improve user experience. It would be quite interesting if Slack works with Microsoft Teams.

For how long have I used the solution?

I have been using the solution for six years.

What do I think about the stability of the solution?

The product crashes sometimes. I've never understood what the problem is. It happens intermittently. I don't know what really makes it crash, but it happens once in a very long time.

What do I think about the scalability of the solution?

The solution is scalable. We are a huge team. We’re about 40 people. All of us use it seamlessly. It achieves our objective as a small team.

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

In 2006, we used IP Messenger. It worked the same way but could be used only in the office. We didn't have any visibility of the communication outside the office. It did not have channels. It had many drawbacks, and Slack solved a lot of those problems.

How was the initial setup?

The solution is quite easy to set up. Anyone can easily set up the product, whether senior employees, junior employees, or professionals.

What other advice do I have?

I use Slack on my desktop. I have it on my phone too. All communications reach me as soon as they are sent, whether I’m in the office or outside. I don't look at the product for improvement. I appreciate what the product is doing. I'm not an administrator. I am a typical user. I joined the Slack channel because I was invited. I have access to Slack as a user, not as an administrator. I used IP Messenger as a software developer for a medium-sized organization in Kenya. We could share files. We could send text messages and all of it. We couldn’t use IP Messenger outside the office. It did not have channels. 

For people who need constant communication and don’t want to rely on emails, Slack is the right tool for them. We can work on the mobile phone to communicate on the go. As long as we have internet connectivity, it is secure. We can create as many channels as we like and collaborate. We can also do voice calls and send voice notes. Overall, I rate the product a seven out of ten.

  • "The solution is scalable."
  • "Its capabilities to provide security features could be better for corporations."

What is our primary use case?

We use the solution for communication within our internal teams and with external organizations.

What is most valuable?

The solution is intuitive, easy to use, and has many essential features. Also, the notifications features for its mobile version work the best. In addition, we can set it up as per our preferences, which is helpful and advanced.

The solution's capabilities to provide security features for corporations could be better. Along with it, the mobile version's calls and sharing video features could be faster.

We have been using the solution for more than four years.

What do I think about the stability of the solution?

The solution's stability for the mobile version could be better as it freezes sometimes. At the same time, it works fine for the desktop version.

What do I think about the scalability of the solution?

The solution is scalable. We have 150 users in our organization.

What other advice do I have?

It is a good collaboration tool. It makes communication within our organization easier. Our Administrators can also lock down the channels for exchanging messages and use them as an announcement tool.

I rate it an eight out of ten.

I rate the solution a ten out of ten.
