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.

The communication tool you can't do without

Slack has improved our communication workflow with our team and improved the way we interact with clients. It allows for multiple language to be spoken by using some translation tools, thus including more staff and especially non-english speaking staff.

Pros

Slack is a great collaborative software that helps users to collaborate across cities, countries, and timezones. It is a crucial part of our project workflow and helps to let developers, project managers, and clients speak to each other in a collaborative enviroment.

It has numerous integrations that allow for third-party apps to interact, create, and receive messages and alerts. These integrations allow us to have one place in which all communications can flow and makes it easier for a worldwide team to be up on the latest updates and critical alerts that may happen.

Cons

The slack tool can be a little battery intensive, especially as you add more slack channels. It also gets quite expensive as you add additional paid members to the group. If you are not aware of all your paid members, or you add guests as paid it can get very expensive quickly.

Because this is a discussion, it is also possible that critical conversations can get lost in the stream of texts coming through.

Slack is the solution for internal communication and collaboration

Slack helps our team stay coordinated, interact in a timely manner, and track information in channels that provide context.

Pros

Slack's ease of use and understanding it paramount. While I find Teams to be over-extending itself into the Office world, Slack is just about making sure you can keep communication clear, timely and open. The ability to shift between private DMs, open channels, and private channels nicely delineates the way you can manage communication across a team. We use Slack for all internal communication, relegating email to external comms, which works really well.

Cons

The channels can overwhelm casual users at times. While the system tries to clean things up with suggestions, I think Slack should do more intentional hiding of under-used channels to keep it clean.

Slack – Managing projects optimally

Slack is a tool which can be used as a project management tool for managing projects and also it can be used for internal communication inside a project group or a company. Each project group can have its own channels inside the company workspace. Communication through private and public channels has made Slack more popular among the users.

Pros

Slack can be considered as a project management tool. Slack provides both mobile version and desktop version applications where the mobile version is installed in the mobile phone so that whatever may be the situation user may not miss any important information about the project instantly. While the desktop version helps to transfer files of the working project easily while working on the project. Slack provides the facility to share the files, folders, audio and video clips, links. there are private and public channels in slack. Users can be added to these channels and if the users prefer they can have their own personal chats through slack. The emojis, stickers, GIF are also added In Slack to provide better user experience and attract the users with its familiar look to most of the social media or texting apps.

Cons

In order to use Slack users need to have a proper network connection. Without proper network coverage, Slack won’t work. Sometimes messages won’t be delivered to the other side after a selected time(10 PM). Unless the user sets his or her state into active user won’t receive notifications after 10 pm. If the state is away then the messages sent after 10 pm won’t be delivered till the next morning. Because of this sometimes users may miss some important messages. It is both an advantage and a disadvantage too. There is no mechanism to know whether the receiver read the message or not once a message is sent. The sender has to wait until other messages come from the receiver acknowledging that the receiver read the message.

Mostly perfect

Slack has been fantastic for keeping our remote workforce connected, fostering a sense of community within our organization, and freeing up our inbox for more important items. There have been a few quirks over the years, but the UI changes have been mostly positive. It seems like the platform is constantly improving with features that are actually useful instead of features for the sake of adding new features.

Pros

Slack Connect is great for facilitating efficient communication with partner businesses, vendors, and clients. Slack was already a vital part of our business and the ability to connect with other organizations on Slack cuts down on email significantly.

Cons

My only complaint with Slack at the moment is that Slack Connect conversations are placed at the top of the conversation list, even above starred conversations. Internal communication is more important to me and not having an option to place conversations with outside organizations below the ones I've determined are most important is an annoyance.

The Best Instant/Group Messaging Platform on the Market

Slack is great at keeping people connected across companies and geographies. I use it both personally and professionally, and I it would be difficult to imagine not using it.

Pros

At least from my perspective, Slack pioneered the modern chat/channel communication platform and it offers the best and fastest experience. I love the seamlessness of switching from chats to channels and finding the thread I need at the moment I need it.

Cons

Unfortunately for me, I work in a Microsoft dominated company that will only pay for MS Teams. If Slack were a clear bargain, I might have a case to get them to switch. However, the paid versions of Slack are a decent chunk of change. That has meant that those of us who like to use Slack must do so on a free account.
