A Simple and Intuitive Communication Tool

In the end, I’m happy with Slack as the primary tool for our organization. However, I’d recommend pairing it with another communication platform, like Teams or Google Workspace, to ensure you have all the features you need. The simplicity of Slack is great, but it can also be a bit of a double-edged sword.

Pros

Slack stands out for its simplicity and ease of use, making it effortless to communicate with colleagues via channels or direct messages. The ability to organize conversations into threads adds a layer of structure, keeping things tidy. Plus, you can integrate it with other tools like GitHub, which can be a real benefit.

Cons

However, compared to Microsoft Teams or Google Workspace, Slack's integrations with third-party services are somewhat limited, which can feel restrictive. While video calls are seamlessly built into Teams or Google Chat, Slack requires an external platform for that feature, which can be a bit inconvenient if you're already using it as your main communication tool.

It's very similar to sending an email because there is no interactive engagement. So for that reason, there are other platforms I prefer (like Teams).

Pros

Slack is easy to setup and you can join a variety of group chats.

Cons

It is not possible to see if your message has been ready or if someone is typing or responding.

My remote team loves slack! So much easier to use than Gmail's chat feature! We love that it is easy to use on our phones, too!

Pros

I love that I can easily communicate with my remote team, schedule impromptu video calls, and integrate apps! I also branded our slack channel to our company's brand!

Cons

Slack will notify you with notes about your apps, tags, etc. It can get confusing if you get a lot of notifications (ex. a note that your google drive file might not be accessible to everyone in the channel). You have to close out the notification to remove it from your channel feed. It's only visible to you, but still annoying!

It’s very basic communication. It’s good for a small team 10 people or less but not good for small business. Compare to Microsoft Teams, Slack has a lot to catch up in terms of versatility.

Pros

It has a free version that everyone can use.

Cons

The search function is not good. Files uploaded or shared cannot be searched.

After using Slack for more than two years, I felt very optimistic that Slack is the most valuable tool for communication, which makes a great replacement for Microsoft Team in the case of smaller teams or smaller companies. From using Discord for my personal uses to using Slack for work, I can really say that Slack works very well in plenty of situations for those who are into messaging.

Pros

Slack has features that allow users to utilize a lot for their work or for other purposes. Highly versatile.

Cons

While Slack is easily thought to be a hard-to-be-replaced tool, I'm hoping there are some improvements, including canvas, lists and developer mode. With these features considered, Slack will be spot-on. I would have expect the creator or developer to implement more features for other criterion other than just messaging.

My company is small and started using it this year. The rollout has been smooth in some cases and bumpy in others. The biggest problem I run into is other users not knowing how to use it. However, as we train each other and our clients, it gets a bit easier everyday and is incredibly.

Pros

There are many things i like about it!
-How many apps it integrates with
-That I can manage projects both internally and externally and communicate freely
-All of the templates are helpful and good quality - many of them are perfect right out of the gate
-That you can communicate via threads so the main message board remains clean and not bogged down with a ton of back and forth
-That you can choose which parts of threads you want to post to the comment board if needed.
-The ability to create workflows

Cons

There are a couple of things I don't like:
-With workflows, you can't create conditional steps. For example, if I want to create a form where the questions change based on the answer to the prior question, you aren't able to do so. You essentially have to make additional workflows/forms for each.
-It gets a bit messy, even if you're great at setting up notifications, channels, communicating through it etc., it can get out of control quickly. Plus, you also have to rely on other people's knowledge on how to use the tool. If someone you're communicating with doesn't know Slack well, you can't be sure if they'll understand how to check for message, have proper notifications etc.

I have used Slack for almost 7 years to manage my team of over 100 contributors. We have group channels as well as team channels for certain teams (writing, editing, design, etc). It's perfect for group collab, one on one convos and group segmentation. I absolutely love it!

Pros

- Ability to have dedicated channels for certain topics
- Ability to have both public and private channels
- Option to create custom emojis (this is just fun)
- Easy to invite teammates
- Easy to @mention teammates and tag them when appropriate
- Excellent for team collaboration
- Supports video calls

Cons

Slack's free plan used to save messages for months now I believe after 90 days the old messages are deleted. This is annoying because we have group rules we have to repost often. That's the only downside.

Slack contributed to achieving more effective communication and response always by ensuring that messages and data are delivered in real time.

Pros

Slack kept communication always available between all team members, gave managers the ability to continuously direct at all times. I liked how it documents the response, achieves transparency in accountability for shortcomings. I liked the ease of creating channels, defining permissions. It is great that Slack gives us the privacy needed to discuss and update data, and separates private communication for work from personal communication applications. Slack is easy to connect with all our applications, making transferring data and sharing everything simpler.

Cons

I did not think about the negatives, the positives are many and the benefits that Slack achieves are great.

When working on a project, it is very important how to collaborate with the participating members. Slack is very good as a service that we create together, such as quick conversation and data sharing.

Pros

Create projects, create channels, and easily invite members.
You can have real-time conversations with the invited members, such as 1:1 conversations and group conversations, and discussions and discussions on various topics within the channel. Also, within the same project, a separate channel for each task can be created and proceeded, so the project can be operated in various forms. And Slack is very light, providing a pleasant service environment.

Cons

I am using only the necessary functions of the slack, so there is no disadvantage yet.
