It's fairly simple to get used to. Also, the cross platform experience between the web version, mobile and desktop apps is impressively smooth.

Valuable Features:

Having group chats and one-on-one chats in one place makes Slack conventient. It's fairly simple to get used to. Also, the cross platform experience between mobile app, desktop app, and web version is impressively smooth. 

Improvements to My Organization:

More often than not, members of our team are on the go rather than in the office. With Slack we have increased communication between teams which has improved executions of complex interdepartmental procedures.

Room for Improvement:

There is some lag at times. Also, would prefer video chat functionality built in rather than as an add-on. 

Use of Solution:

Two years.

Deployment Issues:

Nope. Only colleague resistance on certain teams. 

Stability Issues:

A bit of lag as mentioned. 

Customer Service:

Haven't experienced a customer support representative. Site help docs are fairly strong. 

Initial Setup:

Extremely straightforward. 

Other Solutions Considered:

Yes. We tried Skype, Viber, Gchat. 

Other Advice:

There is a built-in cuteness factor with animated gif options as commentary.

Enhancing team communication and collaboration through organized channels, real-time messaging, seamless file sharing, and versatile third-party integrations
Pros and Cons
  • "It allows to facilitate communication, allowing us to create channels for updates, file sharing, and photo sharing within our team profiles."
  • "Integrating Slack with calendar functions would be advantageous, allowing for the seamless scheduling of meetings within the platform."

What is our primary use case?

We primarily use it for sharing official documents and compositions instead of using platforms like WhatsApp. Although we haven't utilized it for meetings, the main purpose behind creating and using it is to streamline the sharing of official information within our team.

What is most valuable?

It allows to facilitate communication, allowing us to create channels for updates, file sharing, and photo sharing within our team profiles.

What needs improvement?

Integrating Slack with calendar functions would be advantageous, allowing for the seamless scheduling of meetings within the platform.

For how long have I used the solution?

I have been using it for two months now.

What do I think about the stability of the solution?

I would rate the stability eight out of ten.

What do I think about the scalability of the solution?

Its scalability is evident in its ability to handle a varying number of users, channels, and integrations, making it suitable for businesses of different sizes and complexities. I would rate it eight out of ten.

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

We previously employed Google Workspace. Slack provides visibility into the online status of team members when the application is active, it doesn't track users outside of the platform. Unlike some other tools, such as Gmail, where your online status isn't visible to others when you're using it, Slack primarily serves as a communication and collaboration platform.

What other advice do I have?

Overall, I would rate it eight out of ten.

  • "I like Slack's notifications. It is more user-friendly and pleasing than Teams."

We use the tool to communicate with the design team, and exchange links, and code needs. I use it for collaborating with outside spaces.

I like Slack's notifications. It is more user-friendly and pleasing than Teams. 

What needs improvement?

The tool is a bit slow.

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

There are no licensing costs associated with the solution.

Effective integration with applications and easy communication with team members through messaging and calls
Pros and Cons
  • "One thing I like about Slack is the ability to change the color of Slack. It depends on my mood. When I'm having a bright day, I just change the background color of my Slack, which is nice."
  • "We do experience issues when trying to log in on Slack."

What is most valuable?

One thing I like about Slack is the ability to change the color of Slack. It depends on my mood. When I'm having a bright day, I just change the background color of my Slack, which is nice. Then, I need to spend on the mode.

Another thing I love is that you can create different teams on Slack, and you have to give each team a legal name and use an icon. The icons on Slack are beautiful. I especially like the variety of icons available on PeerSpot. Another aspect of Slack is the ability to edit your profile picture. It's a visual icon that you can personalize. Yes, you can bring in your own picture and set it as your profile picture. It's a nice feature.

Also, when it comes to emails, you can navigate your email through Slack. If you have an incoming email, Slack will notify you.

If you have an upcoming meeting, Slack will notify you, or it can notify you about your meetings. I like that feature. Additionally, you can connect other applications like Asana and Trello to Slack. That's how you integrate all those applications into Slack. Then there's SMAX. I've used SMAX before. 

If you want to communicate with your team without using Google or Google Meet, all you need to do is send them a message on Slack. You can hold a call with them. The network usage of Slack is super cool compared to using Google. The networking aspect of Slack is excellent. Also, my friend mentioned that if you want to organize your day-to-day activities, you can create schedules within Slack.

What needs improvement?

Occasionally, we do experience network issues when trying to log in on Slack. However, I believe it's only happened once. It's not a recurring problem.

For how long have I used the solution?

.

What do I think about the stability of the solution?

Slack is a stable solution. I have only experienced one network issue so far, but apart from that, I haven't faced any other problems.

What do I think about the scalability of the solution?

I would rate the scalability a ten out of ten.

How was the initial setup?

It is super easy to navigate on Slack. So, the initial setup is easy.

What other advice do I have?

One thing I appreciate about Slack is that when there's new information or a request from Excel, based on your settings, a notification pops up and informs you that a new update has been added to the team. It's called "Wish It," and it's really helpful for my work. I love that feature. 

Additionally, if you need to save any important information, you can easily do so. Even if you accidentally close the app, the information is still there, which is really cool. Personally, if I were to rate it, I would give Slack a solid ten out of ten. Initially, when I logged into my system, I received notifications for all the information and feedback from the team I needed to access. It automatically directs me to what I need to see.

I would suggest familiarizing yourself with the application, especially its features. Personally, I haven't explored all the features, but some of my friends have, and they highly recommend them. Slack has a lot of useful information and features that you can benefit from. Additionally, you can even create side calls or group calls for your team, like after a game or after work, which is super fun.

A chat tool that large groups can use, but with a need to improve its interface
Pros and Cons
  • "In terms of setup, approaching its menu is simple."
  • "Slack's interface is not simple for me. It's not a user-friendly interface"

What is our primary use case?

I use it if I want to search for information from Kubernetes communities, and then I chat with someone who already has knowledge or knows about Kubernetes. I use it to talk to people using other software like Kubernetes.

What is most valuable?

It is a really trendy tool for uploading information with cutting-edge technology. I can browse all the information to find what I want to really know.

What needs improvement?

In comparison to Teams or other tools, Slack's interface is not simple for me. It's not a user-friendly interface.

For how long have I used the solution?

I have been using Slack for almost three months. I am using its cloud version. I just downloaded it from the internet as a third-party solution or software. I am a user of the solution.

What do I think about the scalability of the solution?

The engineers in their department use Slack. Around 50 engineers use Slack.

How was the initial setup?

In terms of setup, approaching its menu is simple. However, when I went to click and change the account, I was confused regarding whether it was proceeding or not.

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

It is an expensive tool. We pay 15 to 20 USD monthly per user.

What other advice do I have?

I suggest those planning to use Slack to get another social network software such as Teams or Chanty, a tool used in South Korea, are very good. I think Chanty is used in South Korea, especially in the IT sector of Korea.

I rate the overall solution a six out of ten.
