Product Details

What is Slack?

Slack is a Digital HQ
As the command center of the workday, Slack provides a flexible way to work with people, apps and partners in one space.

The new space for success
Slack connects people with each other and with their tools and data, equipping teams to be productive and open up opportunities.

Transform Teamwork
Working together in channels—dedicated spaces built around specific projects and initiatives—keeps the right people and information in one place.

Embrace Flexibility
Huddles let teams chat over audio instantly, with the option for video and screen sharing with the tap of a button.

Work Faster
With clips, teams can create audio, video and screen recordings to share updates, walk through demos or talk out an idea with more clarity (and personality).

Extend Collaboration
Slack Connect lets users work alongside external partners and customers in Slack channels, to speed up projects and strengthen relationships.

Integrate Tools
From project management tools to a daily calendar, Slack integrates with more than 2,400 applications.

Automate Tasks
In Slack, users can turn routine meetings and tasks like standups, approvals and requests into automated workflows.

Well suited: For communication across every / any function of a company and collaborating within teams and outside of immediate team also

Area of opportunity: Maybe having an "offline" version that is still functional without all features enabled during outages

1. Integration with google calendar is very useful. Its notification is very efficient as we only use google calendar in the browser so a notification can be late. With this, we are very aware of the upcoming meetings.

2. Slack workflow and its integration with any google sheet solves the problem for monitoring of all requests within our company. It helps both the requestor and the PIC to maintain a tracker.

I like the plugins and gifs in Slack. It makes the conversations more fun. However, sometimes I also feel it is kind of difficult to follow the key points of the discussions with some gifs. I think Slack can improve that part, for example, limiting the display size of gifs. Meanwhile, I really feel struggling with many channels. It is difficult to navigate between channels if you have too many. Some of them are hidden because they are inactive. In addition, I hope Slack probably can have a more clean version without so many fancy features (just like Skype business).

I would recommend Slack for product teams for quick communication of questions, rapid feedback etc and generally working in a more asynchronous fashion which in turn refines the need for some meetings. Channels are useful for segregating conversations into project-specific initiatives or task forces. It's less suited to housing more comprehensive documentation and conversation; files, links and threads are easily lost in the abyss of channels.

Slack is a useful tool in instances where you need to get your entire company or team utilizing one method of communication outside of email. It's similar to other chat platforms but has a number of additional benefits like the ability for developers to share code back and forth. It might not be useful in instances where employees use it as a distraction.

Last week, we had a bad power interruption that caused me to be late at work. At that moment I'm so very nervous because I'm really certain that my boss will be mad at me! But, I realized I have a Slack on my phone! I contacted my boss right away and report the incident without him being mad because I messaged him quickly via Slack.

This is a great tool for remote working and staying in constant contact with your staff/co-workers. It's like still sitting in the same room without physically being together. You have the opportunity to chat as a group or chat privately with someone. You can create channels to chat about specific topics and organize how it suits you. The new Automation and Canvas features are a plus and gives more options. I honestly I am not sure how it could be less appropriate.. maybe if someone doesn't realize that depending how you setup a channel or conversation, that it may not be entirely private to the Admins.

Love to use Slack for ad hoc huddle sessions with my co-workers. If we need to have a spontaneous call as a group or 1:1, Slack has a seamless experience compared to opening a third party product like zoom to send an individual link. When you are on Slack anyways for text communications, having video and audio at the tip of your fingers is very helpful.

It is certainly well suited for sharing company information quickly and efficiently, in a far more effective way compared to email. As an instant communication channel, it is very effective. It is less effective for detailed document sharing / editing, as the usability does suffer when going into more detailed project work (editing docs etc.). Project management software is more suited for this.

We use it for all internal communications between the departments, especially sending notes and attachments, it is also great for calls between 2 to 4 people. For bigger call meetings I'd still rather use Google Meets because it is better suited compared to Slack. Overall a great tool to use for companies

Slack works perfectly when you want to chime in the conversation very quickly with peers & external entity stakeholders. We can pin the self messages as the save records. Provides great flexibility to the audio, video calls with screen sharing features. At times it lags a bit with slight delays in communications, resulting in poor customer experience. It also lags in saving the self pinned messages.

It's great for keeping groups of people in touch and in sync, no matter the reason: a group of friends, a family, a small business, or a large business. My family even uses it to plan events, share funny pictures, or broadcast important family news. However, it's less appropriate for keeping contact between just two or three people, unless they're working on a complex project that could benefit from sectioning various conversations into specific channels.

Well Suited for: Team Collaboration DM and huddles File and content sharing Less Appropriate: In my opinion, latest UX changes are really bad. I believe the threads are not easy to find and read New messages updates and notifications are not always clear and visible and easily missed in my opinion - which is the whole point of such app

Slack is best suited for project management, team communication, files sharing, audio & video calling, integrating 3rd party tools. Slack is less appropriate for high data security industries where the data is strongly secured and the slack does not provide high data security.

I haven't come across a professional instant messaging service that works as well as Slack. It plugs in to a lot of other work based applications seamlessly like Google Calendars and Zoom. It is a great place to collaborate across the globe as it is sensitive to peoples work/life balance with things like a "do not disturb" mode, the ability to set working hours and schedule message sending.

Slack is so easy to use within companies to communicate across the company, within groups and/or channels, or just communicate with one or a small group of peers. However, when chatting with another peer regarding a patient, it's not a good idea to release any personal information due to HIPAA violations.

Slack is a very useful tool regardless of the size of your teams. To be honest, I don't see a scenario where Slack doesn't fit. From small sized teams for casual projects, to large companies, the tools at hand make it a great way to communicate, consult historical data through chats, and documents. The only reason I would not recommend using it is if your current tool covers your needs and your processes are already oiled up.

Slack is well suited for instant communication, also for calls, sharing screen is a great feature, managing channels, mentions, cards are great improvements we have on that tool I would definitely recommend. The less appropriate is for sharing camera, the quality is not so good and we don't have much personalization on that part.

  • For simple scrum's ceremonies as dailys, Slack is an easy way to do it, since the project already has a channel.
  • Quick calls to colleagues when working from home.
  • Using my own conversation to send drafts
  • Setting personal status
  • Switch between devices is easy
  • Creating groups and channels for different projects and teams

Slack is a phenomenal app. The app is extremely powerful yet very easy to use on a daily basis. Slack excels in keeping conversations organized but that's just the tip of the iceberg. Our entire team uses the built-in reminders to stay on top of tasks and we also utilize channels as how-to knowledge-bases for our customer support reps and other staff members. We use various automations in our business and they all connect to Slack. For example, we use Shopify Flow to automatically send Slack messages in various scenarios:

- When a certain product goes out of stock
- When an order is disputed or is put on hold or has an address change or some other detail we want communicated to the warehouse or a team member
- When the time has come to take on a repeatable task (such as scheduled email list cleaning)
- When an email campaign goes out (so that the warehouse and our customer support reps know to expect a spike in orders/tickets)

We also forward emails to dedicated Slack channels which helps us keep certain information logged and easily searchable/referenced when needed. And finally, we use Slack as a command prompt to trigger automations in Zapier.

Well suited for asynchronous comms to teams who all have varying schedules.
I love the new functionality where you can add a new person to an existing chat and share/forward a chat with other.

Not appropriate for information that needs to be saved or recorded.
Not appropriate for formal communication to teams.
Not appropriate for collaboration with external users.
