What is Slack?

Slack is a group messaging or team collaboration app that aims to simplify communication for businesses. Features include open discussions, private groups, and direct messaging, as well as deep contextual search and message archiving, and file sharing. Slack integrates with a number of other tools, such as MailChimp, Dropbox, and Google Drive. Slack was acquired by Salesforce in December 2020. The product is free to use, and also has paid plans with more features and greater controls. The company has raised $340M in funding and boasts 800k users.

Use Cases and Deployment Scope

I am using Slack for my daily professional communications and integrations with my apps like Google Docs and Loom Video. I like how it can make channels for each project/task and you can discuss all the details of that specific topic there. I also like the integration of my Project Management software "Trello", because it can tell me about the updates happening in trello and I can update that cards back by staying in Slack.

Pros

Communication
Project Management
File Sharing
Integrations with various Apps

Cons

Backup of messages for low tier packages
Nicer way to show the data from integrated apps
Time zone / Notifications

Use Cases and Deployment Scope

We use Slack as our primary communication tool. Not just for internal messaging, but for work flows such as when a customer gets their first sale using our tool, or if they churn or if they install. We really love the integrations with other apps and salesforce. The ability to communicate via message, group chat, channel or huddles with live video is awesome.

Use Cases and Deployment Scope

So we use it for daily collaboration, just notifications for different things that happen. We're solely building out automation in Slack. We integrated it from Salesforce so that when something happens in Salesforce, we want to notify the users in Slack and send our automated reminders. That's what we're using it for.

Pros

I think it's the whole collaborative feature, and now with Slack coming into Salesforce and Salesforce being able to be seen from Slack, I think it's going to be amazing.

Cons

I can't think of anything right now

Return on Investment

I think it has been great to help distributed teams collaborate and work faster and quicker. Nobody's now bound to a computer or has to log into Salesforce, so everything is going to be visible on your phone, on the track.

Use Cases and Deployment Scope

As a remote company, we primarily use Slack as our primary communication method, rather than email. We have "channels" for specific customers, our whole organization, live incidents, marketing, teams that collaborate, etc. This is a much more efficient and organized way to communicate compared to email. It is faster, more precise, and you can easily track the conversation's history.

Pros

Great simple interface. The use of emojis is high to express gratitude or confirm receipt of a message, without requiring every person to add additional messages.
You can start a side conversation in a group message to silo some conversation and not have those messages clutter up the main page.
It's reliable and easy to use. simple interface. You can also live chat with someone and share your screen, which is heavily used by our team.

Cons

I would love it if Slack had some AI to help summarize and document information spoken from live chat meetings or within messages.
There is an option to pin messages, allowing you to reference them later within a chat easily. I would like to see this implemented for all channels and messages, allowing each user to use it as a to-do list.
I would like it if, on Slack live chats, you could turn on our screen to see the other person; currently, it is just voice communication.

Return on Investment

We work faster and more accurately, everyone is able to follow along, and if you are added to a conversation, you have the option to see all the previous messages or not.
Helps us work more effectively with team members from different time zones, as Slack notifies us of this.
Our collaboration is streamlined.
