It has a narrow set of features focused on team communication. I guess that's why it works well.

What is most valuable?

  • Channel conversations, because it's an easy way to get to a few people or a whole team at the same time.
  • Private conversations, because they're simple, convenient and they work!
  • Slackbot reminders, because it's a simple way to set a reminder for yourself or a colleague, without messing with calendars.
  • Integrations. For instance, thanks to integration of our own application Woodpecker.co with Slack through Zapier, we get notified each time one of our users starts the paying process and each time they complete it. We can actually see the new customers coming on board in real time.
  • Slack is just a communicator, no more. It has a narrow set of features focused on team communication. It's simple. I guess that's why it works so well for us.

How has it helped my organization?

Everyone's up to date with what's going on in our product development, marketing and sales. We communicate faster and no one has any troubles learning how to use the communicator.

What needs improvement?

I would like to see if someone has already read my message, but that's just a whim, not really a necessary must-have feature.

For how long have I used the solution?

We have used the solution for over two years.

What do I think about the stability of the solution?

We hardly ever had any issues with stability. I remember Slack was only down once over the whole time I've been using it so far.

What do I think about the scalability of the solution?

We haven't yet had any issues with scalability, but our team is quite small with only 17 people at the moment.

How are customer service and support?

In fact, I never felt the need to contact support, so I have no experience with that, but I guess that's great!

Which solution did I use previously and why did I switch?

We used a number of solutions which were really only a feature of a bigger product.

How was the initial setup?

The setup was simple for me, but I was joining the team someone else set up.

What's my experience with pricing, setup cost, and licensing?

We're using the free version and some people from our team wish that the message history had not been removed, so if you sometimes need to go back a few months in a conversation, the paid version would be something to consider.

What other advice do I have?

Definitely give Slack a try.

Provides integration between devices, effective organization of shared content, and syntax highlighting.

What is most valuable?

  • Seamless integration between devices
  • Effective organization of shared content (documents, images, etc.) keeps team on same page
  • Syntax highlighting
  • Nice overall UX

How has it helped my organization?

Slack kept several remote employees working cohesively and seamlessly together, allowing us to more easily synchronize our efforts and work collaboratively rather than "islands unto ourselves," so to speak. Coding, writing, editing, etc. was all done in an effective manner, as a result.

What needs improvement?

Honestly, I feel like I am nitpicking when I say the UX can be improved. But it is true, incrementally, the UX could see an improvement through extensive tweaking and testing.

For how long have I used the solution?

I have used it for three years.

What was my experience with deployment of the solution?

We have not encountered any deployment issues; it was very smooth.

What do I think about the stability of the solution?

Slack has proved to be the most stable communication tool I have used, to date.

What do I think about the scalability of the solution?

We have not encountered any scalability issues; large teams seem to be handled quite well.

Which solution did I use previously and why did I switch?

I previously used HipChat. The decision was not mine to switch, but I found the switch to be a very positive one. Slack was just more slick, especially with sharing content and keeping a history of it, visible to conversation participants as needed.

Some of the valuable features are managing notifications, status updates, and reminders.

What is most valuable?

  • Managing notifications
  • Status updates
  • Reminders
  • Selective involvement in conversations with relevant threads when they are of value
  • Avoidance of email clutter
  • Bots which enable focused streams of information available in one place for the relevant, interested people
  • All kind of integrations: File sharing services, application performance management, incidents and monitoring alerts, which are flexible and easy to develop through an API
  • A powerful search through chat history to find references and pieces of information promptly
  • Recent threaded comments feature

How has it helped my organization?

  • Increased productivity avoiding email "chat" and creating space for focused conversations which are topic or action oriented
  • Increased visibility and "situational awareness" of people in the team at their own pace (asynchronous), avoiding interruptions
  • Increased serendipitous communication and shared thoughts on general channels.

What needs improvement?

Better ways to help people get up to date when away from a conversation for a long time, or after bursts of a particular discussion.

Slack has different features to follow up on updates when not directly through notifications.

You can use Show Activity to see where you have been mentioned recently.

You can mark items with Stars to follow topics in a kind-of to-do list. And even if you have a granular control on mobile push and email notifications, when you have been away for sometime, or visit the channel from time to time, and there are channels with a lot of activity, you can have some difficulties to go through the new messages since, without risking to confuse important from non-important conversations.

Recent threaded messages help people center around topics, but still where there's people that come to the channel from time to time, they can feel overwhelmed to go through everything since last time.

Some summary feature can help target most heat or important messages or conversations, or some kind of view of the recent messages by "heat" level (kind of the sorting algorithm of Facebook or LinkedIn for the news feeds).

For how long have I used the solution?

We have been using the solution for one year.

What do I think about the stability of the solution?

We have not encountered any stability issues. It is a very simple, effective, and stable solution.

What do I think about the scalability of the solution?

We have not encountered any scalability issues.

How are customer service and technical support?

We never required the technical support.

Which solution did I use previously and why did I switch?

  • Email
  • Mailing lists
  • Forums
  • Internet relay chat
  • Wikis

In the cases where it fits best with the team, Slack can be a replacement and enhancement to collaboration, increased productivity, and reduced clutter in email.

How was the initial setup?

The setup is very easy. I was responsible for implementing it. It required a low level of expertise to deploy and administer. It required a medium level to manage integrations and to develop integration over other software towards Slack through its API.

Which other solutions did I evaluate?

We evaluated HipChat and Yammer.

Microsoft Teams was not out yet, which may suit companies with a Microsoft toolset.

Facebook Workplace wasn't yet available.

Interestingly enough, Slack is even more friendly in all platforms including a native Linux client, and has an excellent browser based version.

What other advice do I have?

Consider the resistance to text based communication of people not used to it and those with a fear of transparent communication who are worried about the saturation of technologies.

Some gamified training can help and advocate in order to guide, moderate, and curate the channels, set some "netiquette", and encourage use and constructive behaviors.

People are getting used more and more used to text based communication through Whatsapp and other apps.

Consider that it has a strong community across the world and that is a powerful source to leverage.

This product is so flexible and powerful that it can be used as:

  • Virtual space for teams
  • Topic or action based rooms
  • A bot answered service channel
  • A back channel for events
  • A lot other use cases depending on team appetite and creativity

Certainly within the right culture, it will enhance and reduce friction in communication.

Integration with third-party automation services has significantly boosted productivity.

What is most valuable?

The integration with third-party automation services such as IFTTT and Zapier has significantly boosted productivity.

We receive automatic notifications of certain business activities and planned events, instead of having to send out manual emails to disseminate that information.

How has it helped my organization?

It has encouraged more transparent communication, getting more staff members exposed to and involved in different areas of the business.

What needs improvement?

Many of the advanced features and integrations are built with developers in mind. More functionality and integration for other use cases would be welcome.

Slack integrates with bots that automate tasks and add functionality. A large portion of these bots do things specifically to help developers do their jobs, such as accessing code repositories and sharing code with colleagues.

It would be great if there were more bots and third-party integrations that targeted other groups of potential Slack users.

For how long have I used the solution?

We have been using the solution for 18 months.

What do I think about the stability of the solution?

We have had no major issues with downtime or with the apps crashing.

What do I think about the scalability of the solution?

We are using the free version, which only keeps a limited number of messages archived. As our team has grown, we go through this archive allotment fairly quickly.

How are customer service and technical support?

We have not had to use technical support.

Which solution did I use previously and why did I switch?

We did not previously use a different solution.

How was the initial setup?

The solution was very easy to set up. I created the team through the Slack web site, which automatically invited everyone else via email and instructed them to download the client apps.

What's my experience with pricing, setup cost, and licensing?

The free version can do pretty much everything you need it to. You'll have to pay if you have a large team or if you have specific security and compliance requirements.

Which other solutions did I evaluate?

We did not evaluate any other products.

What other advice do I have?

Make a significant effort to get user buy-in right from the start.

If people see it as just another system, not a powerful email reducer and productivity booster, adoption will lag.

You really need everyone on the team to be on board for it to succeed. If even one person sticks to email-first communication, it makes everyone else rely more on email, which defeats the purpose of having Slack.

Mac version built into Safari has a lot of informative space and allows for custom CSS.

What is most valuable?

Mac version built into Safari has a lot of informative space and allows for custom CSS (right click > inspect elements) if you want it more personal and/or something puts you off in the standard settings.

Tons of integrations and bots makes it unique.

What other advice do I have?

Use what works best for your team and what your team knows best.

It's fairly simple to get used to. Also, the cross platform experience between the web version, mobile and desktop apps is impressively smooth.

Valuable Features:

Having group chats and one-on-one chats in one place makes Slack conventient. It's fairly simple to get used to. Also, the cross platform experience between mobile app, desktop app, and web version is impressively smooth. 

Improvements to My Organization:

More often than not, members of our team are on the go rather than in the office. With Slack we have increased communication between teams which has improved executions of complex interdepartmental procedures.

Room for Improvement:

There is some lag at times. Also, would prefer video chat functionality built in rather than as an add-on. 

Use of Solution:

Two years.

Deployment Issues:

Nope. Only colleague resistance on certain teams. 

Stability Issues:

A bit of lag as mentioned. 

Customer Service:

Haven't experienced a customer support representative. Site help docs are fairly strong. 

Initial Setup:

Extremely straightforward. 

Other Solutions Considered:

Yes. We tried Skype, Viber, Gchat. 

Other Advice:

There is a built-in cuteness factor with animated gif options as commentary.

Used to communicate within the team and with other people outside the company
