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.

Use Cases and Deployment Scope
Slack has been our main communication platform for a few years now. We are so deep in it that, Slack has even replaced "email" as the main or formal form of written communication. We use it across the whole organization, for all departments, for absolutely all employees. And we didn't force this change. It actually happened on its own pace organically, due to the great value the platform gave to everyone on their day to day way of work. We have even brought in customers and suppliers into the system. Heck! We have designed a huge part of our delivery model to happen within Slack. The history of this company is divided in two: before and after Slack!
Pros and Cons
  • Slack is amazingly easy to use. People have been using chat applications for decades now, so Slack feels just like a chat app. There's practically no friction, or at least I didn't see one among all type of users.
  • The great amount of possible integrations with other systems makes Slack even a more seamless experience. When you start integrating Slack with your other systems, Slack starts to become the main hub for everything that it is going on, on your day to day. It becomes the main tool for work.
  • The pricing model is very fair. You only pay for the users who actually use it. This is especially helpful if you are bringing people in from outside the organization.
  • The mobile apps, both phone and tablet, are super stable. Same experience than with the desktop one.
  • None.
Likelihood to Recommend
I don't see how a company wouldn't need something like Slack. In its most basic form, it is a real-time communication platform, which is something all organizations need. Slack performs especially GREAT on remote team-based types of work. Since all communications happen through the platform, everyone is aware of what's going on with each other's work.

Return on Investment
  • All the positive impact! We have integrated slack to our delivery model, literally. We operate on top of it and the results have been all positive. The most obvious being having everyone on the same page. Good communication.
  • People is working smarter. By making communication easier and efficient, errors in operation have been reduced greatly.
Alternatives Considered
Slack was designed specifically to a work/business environment, so it stacks up pretty well against most competitors. I think they actually created a new industry standard. Nobody was controlling the "team/company communications tool" space before. And they are updating the system constantly so they stay on top of the market, feature-wise. I haven't seen anything better out there.

All business functions. Is the main and official communications tool
Support Headcount Required
You only need to know how to read. They have very good documentation in case you can figure out stuff, which I'm sure anyone can. I've never seen anyone needing help with slack. It is so easy to sue that everyone figures it out by themselves.
Business Processes Supported
  • day to day real time communication
  • communication organized by departments, areas, teams, projects, etc.
  • People on the go can stay connect through the mobile apps
Innovative Uses
  • We built our delivery model on top of it. We stay connected on a daily basis with clients by inviting them into the platform
  • We have invited also suppliers. Communication with them is quick than ever.
Future Planned Uses
  • The coolest thing is that you can actually get creative with Slack. There are so many 3rd party integration with so many different systems that you can build crazy scenarios or workflows using slack as core.

Use Cases and Deployment Scope
We use slack for our IT department so we can keep in constant contact with everyone. We also have it where anytime our ticketing system or alert system gets activated it will alert the proper channel in slack so the entire team knows what is going on.
Pros and Cons
  • channels. This is great for our team so we can separate the chat depending on what it is about.
  • private message. It's great so you can message just one team member or pull several people into one chat.
  • history. it is great so you can search on items discussed months ago to recall what was said.
  • search. I would like to be able to search just one channel not everything
  • separate logins. would be nice to have everything on once screen so you don't have to switch back and forth.
Likelihood to Recommend
Just to private message its overkill. For a team environment where you need to talk to many people in groups or alone it is great tool to have.

  • We have moved from Skype/lync chat to slack for our IT team. It has been a better service for our team over what Skype/lync pchat could do.

There is not a lot needed to support slack. It just works the only hard part is creating channels if you need that and really anyone can do that its not hard at all.
Business Processes Supported
  • Private messaging between IT staff
  • Group chat for our different locations and as a whole team
  • Project chat so we can add the team members that are working on the project so we don't flood the main channel with project chat.
Innovative Uses
  • We started working with an outside source for a project and was able to add him to our project chat.
  • We use slack over Skype business for our team chat
Future Planned Uses
  • Not sure of what else we can do that slack is able to do.

Because it is a important product for our team and we use it everyday.
Products Replaced
Yes
We replaced Skype for Business with slack for our IT department.
Key Differentiators

  • Product Usability
The ease of use and the fact we can use it on our iphones when we are out of the office was a great factor. The other was that we can setup different groups to chat on projects.
