About Slack

Slack is a cloud-based project collaboration and team interaction tool designed to facilitate communication across organizations. The solution caters to various industries, including media, research, technology, education, financial services, retail, transport, and logistics. Slack provides public channels for members across organizations to start conversations. Private channels enable interaction within smaller teams, and direct channels help send messages directly to colleagues. Slack incorporates feeds from social media into the application and blends them with ongoing conversations in various channels. Files such as PDFs, images, documents, and spreadsheets can be shared via drag and drop. Slack archives messages, notifications, files (as well as the contents of files) and projects, all of which can be searched for later. Slack allows users to customize their notifications and reduce their scope. All changes are reflected in the native applications available for iOS and Android.

PERFECT BRIDGE BETWEEN AGENCY AND WORKERS

Slack qualifies to be the best collaboration tool of our generation with users navigating the app with quite a lot of ease. The experience at large is very positive and with such competitive prices, indeed there lies infinite potential with slack. It offers several intergrations iclusive of outlook and zoom among other essential plugins.

Pros

As a messenger app, the basic functions enabling communications are on a perfect edge with a simple, precise interface very easy to navigate. The search option comes in as a plus as you are able to trace your target messaage on a long thread with simple typing of words on the search bar. With slack, we are able to share files with quite a lot of ease and now with the IRC style, we can separate the conversation threads in the presence of multiple members in a team to set up off-topic discussions.

Cons

When sharing your screen with another team or individual, you have to go back to the initial chat to send a message, I would prefer this being done from the same UI of the screen-share. Also the limitation to the number of users attending a video conference does not confer with large organisations such as ours.

Not bad for small groups, horrible for large groups, free plan is now crippled

Only using Slack with external teams that use them. We no longer use it with our internal teams. Their confusing threaded views is really their downfall. There are other alternatives out there that do a much better job.

Pros

Slack has a very nice, slick interface. When the workspace is not busy, it's very easy to see all the messages and figure out what's relevant for you. Very easy to setup new workspaces and channels. And basically, the key reason why we use Slack is because almost everyone is using it.

Cons

Their free plan is now crippled. Only 90 days of retention. On a number of free workspaces, I wanted to refer back to some info which I no longer can find. Very frustrating. Slack also implements threaded conversations as a "tack-on" feature. Not everyone uses this feature and it just causes more and more user confusion, especially in large workspaces where many messages are mixed into the main channel as well as in threads. Their threads/mentions&reactions views which are supposed to help you filter out things not relevant for you are huge messes. Their pricing plans are also very expensive.

Alternatives Considered

Mattermost, Zulip and Microsoft Teams

Reasons for Switching to Slack

We're no longer using Slack internally. Only for external communication with teams that insist on using it. MS Teams offers better integration with their Office suite. Zulip offers superior threaded conversations and formatting at a much more reasonable cost.

What I like most about Slack is the ease of use and how simple/straight forward it is. I'm able open the application and connect to and talk with my teammates in real-time.

Cons

Honestly, there is not much that I can say negatively about Slack because it just works. I'm able to accomplish my task with no problems

Cons

Ever since I started using Slack, it has never disappointed.
