Use Cases and Deployment Scope

1. Automated workflows and audit trails 2. Convenient way to collaborate and keep a simplified runbook through canvas for the team's access 3. Keeping in touch with teammates located in different timezones. 4. Community channels allows for a more informal way to communicate with everyone in the firm - as a chatline about upcoming internal company events, early bird sales to external events, lost & found, etc.

Pros

Automated workflows
Collaboration
Private and public channels
Application linkage

Cons

Ctrl + K being allowed to be the "link" or URL function would be great and very in line with other softwares/web browsers
Customized ordering of starred conversations

Likelihood to Recommend

Slack is well suited with it's ability to connect with external applications. Our team uses this to link / preview external documents (such as Google Docs) on our canvas. This is especially useful for us collating ideas or building up the runbook which requires us to link to the documents of other teams' due to linked processes.

Use Cases and Deployment Scope

We use it to communicate amongst ourselves and other team members. We also use it to communicate with our customers that also use it! It is easy for everyone to use and effectively gets the job done. I would highly recommend this product to anyone who needs a reliable communication channel.

Pros

Notifies quickly
Easy to have different threads
Easy to use for all people

Cons

Logs me out occasionally
could be easier to upload pictures
could be easier to upload documents

Likelihood to Recommend

Slack is great for everyone to sue all around. My only issue is that it can be challenging to to upload and send any form of photos or documents. This could be made easier. My team enjoys the easy use of channels and different threads with specific names to help keep track.

Use Cases and Deployment Scope

Slack is primarily used for quick alignment on topics of concern Groups and channels help us quickly huddle as a group and get to the root of the issue we are solving in short time We also use the bookmarks for Slack access to imp docs and any files that need bookmarking

Pros

Communicating ideas
Collaboration
Access to information from channels

Cons

Messages get lost
Too many nested messages in some cases
I cant copy paste with Slack on phones

Likelihood to Recommend

Its great as a collab / alignment. / quick huddling tool

Its still not that great with its integrations to bots and AI Apps - whoch will really unlock a lot

Its integration to JIRA can be better and its ability to integrate into meetings like Teams is non existent today and needs work

Versatile communications hub

December 3, 2025

Use Cases and Deployment Scope

It is the primary means of communication for all of our company's operations. We DM, huddle, and organize our teams by channels. We also use Asana, Figma, and Outlook, but generally there are communication breakdowns that tend to occur, and Slack is the main touchpoint that we update each other on, even when we've tagged co-workers in other platforms. Slack always gets seen. Its mobile app is also very capable for remote work.

Pros

SubChannels
Emoji reacts
Huddles
Screensharing
Easy links in text

Cons

Messages tend to get buried quick on fast moving projects.
There should be an organization suggestion for when people have messy DM threads
Should be able to refine notification settings to only hear from one person, or a few people, rather than types of notifications

Likelihood to Recommend

It works great for quick, informal collaboration—things like real-time problem solving, fast project check-ins, brainstorming, sharing files or references, and keeping a distributed team connected. It shines when communication needs to be fast, flexible, and visible across a group. However, it’s less appropriate for anything requiring long-term documentation, careful nuance, or formal record-keeping—such as scope changes, contracts, detailed feedback, sensitive HR matters, or client negotiations—where email, meetings, or shared documents provide clearer structure, permanence, and accountability.

Make work communication and productivity fun

Use Cases and Deployment Scope

In a world of corporate all in one solutions, where businesses are insisting that all employees use Microsoft Teams, Slack is a sleek, fun, modern take on communication which when implemented right in a business, can bring a lot of engagement and life to communication which can otherwise become bland and sterile.

Pros

Engaging communications
Modern design
Enabling features for your work

Cons

Lack of integration with other platforms
Huddles are so bad, you'll have to use Zoom
Steeper learning curve for Microsoft users

Likelihood to Recommend

Slack is a great communications platform, it's 'Channels' feature is a much better approach to social communications than Team's 'Teams' function, and it pairs really nicely with it's management features and custom emote support. Slack also has some great features such as Canvas which can be used in a variety of ways such as for onboarding employees.

The go-to tool for software teams communication

Rating: 9 out of 10

November 6, 2025

Use Cases and Deployment Scope

We use Slack to communicate within our team, share updates, and plan meetings. We also use it to connect with the teams of our customers or our partners. Sometimes we also use it to communicate with vendors.

We use 1to1 messages for day-to-day communications, and the channels for company updates and as a central knowledge base history.

Pros

Messaging
Threads
Channels
Connecting with other teams (clients, partners, vendors)

Cons

Desktop app performance
AI automation and workflow improvements
Memory consumption

Likelihood to Recommend

It's amazing for small team communication. As well as having a dedicated channel with company updates (automated and manual) where everyone can pin in the thread.

This helps keep everyone on the same page while maintaining the async company culture.

It's also really great to keep in touch with customers, and provide direct support without the need to have tickets or another form of format communication.

Colleague communication.

Pros

Direct communication with teams, group chats and channel to bring people and subjects together.

Cons

Limitations on group chats where it's only limited to nine people and then you have to make it into a channel, which is pretty frustrating because you can't remove people out of a group, which is boggling. Drives me nuts.

Likelihood to Recommend

Colleague communication — that’s what we use it for the most. I think other teams might use it in other ways, but for me, it’s like the WhatsApp of the Salesforce world when it comes to corporate communication. As for where it’s less appropriate, I honestly don’t have an example off the top of my head. It doesn’t replace in-person connectivity, but for remote workers, it’s a necessity.

Use Cases and Deployment Scope

Slack is something which made, honestly made our life really easy. Right before Slack we used to have a lot of different tools, maybe Google Meets or Microsoft Teams and all the whole idea of using the Slack where we have all the documents, all the information handy. We can create the different groups channel, we can add external people as well. And especially when you're coordinating with the Salesforce team, they are on Slack and without, if you're not on Slack, then you can't communicate with them. That's how it's helping us and our team very well. I think it's a great tool in terms of the communication, in terms of restoring the data, in terms of seeing what kind of the history, in terms of creating the different channels, in terms of sizing, something which is you want to hide from the others, but you want to do collaborative environment. So Slack can come and play a very important, that's what I love.

Pros

You can share the documents link
Create the channels
Invite the unit, the people from the external organization. They don't have to have the paid version of Slack. So teams, if they don't have a paid version, they cannot go for it. But Slack, they can try it, they can use it, and if they love it then they can go for it.

Cons

I mean Salesforce is really the innovative organization. They always come up with a different thought process all. So to be honest, I feel it very good. But yeah, they might want to come up with something different and maybe add down the line in future. So no, not at this moment.

Likelihood to Recommend

See, in every scenario, Slack is good, right? Because it's all about communicating how you coordinate with your team and all. I mean, if there is no communication within the team, then to be honest, you don't need any tools, whether it's Slack or any other platform. So it's better all the different scenario, wherever it comes. Communication, internal, external, sharing the information, creating a group Slack payer. So yeah, it's good.

The best product of its kind on the market

Rating: 10 out of 10

November 5, 2025

Use Cases and Deployment Scope

Each and every member of the company gets a Slack account on their first day, and we use it for all internal messaging and ad-hoc calls. It means that in this working from home age, everyone is simply a message or call away and everything is logged, which is crucial to our businesses day to day operations. It allows for cross-collaboration between departments which would otherwise be made difficult without Slack.

Pros

Ease of use
Simple to implement
Great messaging service

Cons

Ease of use - it is very much a 'pick up and play' software that does not take any time at all to get used to for new starters
Simple to implement - to create new users and just set up and integrate the system into our company could not have been easier
Great messaging service - it is a seamless way of messaging colleagues

Likelihood to Recommend

Slack is suited to larger businesses that have many employees, as I feel it's main strength is in the way it easily allows you to find anyone to direct message instantly, and how easy it is to setup endless channels to cover all the different departments and projects that may be ongoing at any one time.

Teams Vs Slack Mortal Kombat

Rating: 9 out of 10

November 5, 2025

Use Cases and Deployment Scope

Slack has been instrumental in helping us with interdepartmental communications across the globe as well as opening a clear line of communications with our clients. We have offices all over the world and real time communication had been a challenge. With all of Slack's integrations and the ability to send messages as well as files in real time has helped us tremendously. Additionally, whenever we onboard new clients we typically ask that we start a Slack channel for our communications.

Pros

Integrations
file sharing
group chats
notifications

Cons

More options for customizations
Color coded channels
The ability to be see all workspaces in one view

Likelihood to Recommend

Slack has been instrumental in the way we run projects. Because different teams sit in different offices, when we collaborate we always keep logs of our progress in a dedicated Slack channel which can be assigned a different name. Also, we prefer to communicate with clients via Slack if they already have a dedicated Slack workspace and simply ask they create a channel.
