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.

Helps to communicate with teams and share links
Pros and Cons
  • "I like Slack's notifications. It is more user-friendly and pleasing than Teams."
  • "The tool is a bit slow."

What is our primary use case?

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

What is most valuable?

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

What needs improvement?

The tool is a bit slow. 

For how long have I used the solution?

I have been using the product for six years.

The product is a bit slow but stable. 

What do I think about the scalability of the solution?

Slack is scalable. 

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

How was the initial setup?

Slack's setup is easy. The product does not require any maintenance. 

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

There are no licensing costs associated with the solution. 

What other advice do I have?

I would rate Slack a five out of ten.

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?

On-premises

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 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.

What do I think about the stability of the solution?

It is fairly stable.

What do I think about the scalability of the solution?

It can be scaled very easily. We have about 20 people who use this solution.

How are customer service and support?

I have not used their support so far.

How was the initial setup?

It was straightforward. It took one day.

What other advice do I have?

It is good. It is one of the best ones out there. You can definitely go for it. 

When you're partnering with teams outside your organization, you can't really do without Slack. It becomes a necessity. We chose this solution because Slack was the most widely used solution. 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.

Some of the valuable features are managing notifications, status updates, and reminders.

What is most valuable?

  • Managing notifications
  • Status updates
  • Reminders
  • Selective involvement in conversations with relevant threads when they are of value
  • Avoidance of email clutter
  • Bots which enable focused streams of information available in one place for the relevant, interested people
  • All kind of integrations: File sharing services, application performance management, incidents and monitoring alerts, which are flexible and easy to develop through an API
  • A powerful search through chat history to find references and pieces of information promptly
  • Recent threaded comments feature

How has it helped my organization?

  • Increased productivity avoiding email "chat" and creating space for focused conversations which are topic or action oriented
  • Increased visibility and "situational awareness" of people in the team at their own pace (asynchronous), avoiding interruptions
  • Increased serendipitous communication and shared thoughts on general channels.

What needs improvement?

Better ways to help people get up to date when away from a conversation for a long time, or after bursts of a particular discussion.

Slack has different features to follow up on updates when not directly through notifications.

You can use Show Activity to see where you have been mentioned recently.

You can mark items with Stars to follow topics in a kind-of to-do list. And even if you have a granular control on mobile push and email notifications, when you have been away for sometime, or visit the channel from time to time, and there are channels with a lot of activity, you can have some difficulties to go through the new messages since, without risking to confuse important from non-important conversations.

Recent threaded messages help people center around topics, but still where there's people that come to the channel from time to time, they can feel overwhelmed to go through everything since last time.

Some summary feature can help target most heat or important messages or conversations, or some kind of view of the recent messages by "heat" level (kind of the sorting algorithm of Facebook or LinkedIn for the news feeds).

For how long have I used the solution?

We have been using the solution for one year.

What do I think about the stability of the solution?

We have not encountered any stability issues. It is a very simple, effective, and stable solution.

What do I think about the scalability of the solution?

We have not encountered any scalability issues.

How are customer service and technical support?

We never required the technical support.

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

  • Email
  • Mailing lists
  • Forums
  • Internet relay chat
  • Wikis

In the cases where it fits best with the team, Slack can be a replacement and enhancement to collaboration, increased productivity, and reduced clutter in email.

How was the initial setup?

The setup is very easy. I was responsible for implementing it. It required a low level of expertise to deploy and administer. It required a medium level to manage integrations and to develop integration over other software towards Slack through its API.

Which other solutions did I evaluate?

We evaluated HipChat and Yammer.

Microsoft Teams was not out yet, which may suit companies with a Microsoft toolset.

Facebook Workplace wasn't yet available.

Interestingly enough, Slack is even more friendly in all platforms including a native Linux client, and has an excellent browser based version.

What other advice do I have?

Consider the resistance to text based communication of people not used to it and those with a fear of transparent communication who are worried about the saturation of technologies.

Some gamified training can help and advocate in order to guide, moderate, and curate the channels, set some "netiquette", and encourage use and constructive behaviors.

People are getting used more and more used to text based communication through Whatsapp and other apps.

Consider that it has a strong community across the world and that is a powerful source to leverage.

This product is so flexible and powerful that it can be used as:

  • Virtual space for teams
  • Topic or action based rooms
  • A bot answered service channel
  • A back channel for events
  • A lot other use cases depending on team appetite and creativity

Certainly within the right culture, it will enhance and reduce friction in communication.

Integration with third-party automation services has significantly boosted productivity.

What is most valuable?

The integration with third-party automation services such as IFTTT and Zapier has significantly boosted productivity.

We receive automatic notifications of certain business activities and planned events, instead of having to send out manual emails to disseminate that information.

How has it helped my organization?

It has encouraged more transparent communication, getting more staff members exposed to and involved in different areas of the business.

What needs improvement?

Many of the advanced features and integrations are built with developers in mind. More functionality and integration for other use cases would be welcome.

Slack integrates with bots that automate tasks and add functionality. A large portion of these bots do things specifically to help developers do their jobs, such as accessing code repositories and sharing code with colleagues.

It would be great if there were more bots and third-party integrations that targeted other groups of potential Slack users.

For how long have I used the solution?

We have been using the solution for 18 months.

What do I think about the stability of the solution?

We have had no major issues with downtime or with the apps crashing.

What do I think about the scalability of the solution?

We are using the free version, which only keeps a limited number of messages archived. As our team has grown, we go through this archive allotment fairly quickly.

How are customer service and technical support?

We have not had to use technical support.

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

We did not previously use a different solution.

How was the initial setup?

The solution was very easy to set up. I created the team through the Slack web site, which automatically invited everyone else via email and instructed them to download the client apps.

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

The free version can do pretty much everything you need it to. You'll have to pay if you have a large team or if you have specific security and compliance requirements.

Which other solutions did I evaluate?

We did not evaluate any other products.

What other advice do I have?

Make a significant effort to get user buy-in right from the start.

If people see it as just another system, not a powerful email reducer and productivity booster, adoption will lag.

You really need everyone on the team to be on board for it to succeed. If even one person sticks to email-first communication, it makes everyone else rely more on email, which defeats the purpose of having Slack.

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.
