It is best suited in all sorts of organization, small or big, it well suited in all firms. Its best use is that it can be used to form a group for communicating with our colleagues while working on a common project. It also can be used as a reminder for our important stuff.

How our remote offices use Slack to remain connected

We have a remote work environment as well as several international offices. We needed a tool that allowed us to communicate among individuals, teams and different parts of the organizations (Product, Support, etc). By using Slack, we can easily share information, create unique channels to share data and then integrate many other tools that we regularly use. The in platform phone allows us to easily call one another as well.

Slack has been built to work on your web browser, as an app on your computer, and an app on your smartphone. Slack has spent the money to make sure that their program rarely has downtime. I love how easy it is to communicate with my co-workers on Slack. It is easier than sending an email to a co-worker. Slacks improves efficiency in the company because employees are able to communicate with each other with ease especially if the company has multiple locations across the country or across the world. Slack will even let you know what time it is for the recipient you are sending the message to which is great if you have overseas employees.

Slack is very easy to use and can be very effective. I enjoy speaking through gifs, so the Giphy option is very friendly and always adds some fun to my communication. I am able to communicate with all members of my team, regardless of where they are in the US.

Slack is a very good tool for maintaining communication between departments and managers in any company.

Slack is very good at creating communities and establishing links with departments of any organization, which makes this tool a fundamental pillar in terms of communication. However, Slack cannot be relied upon to implement action plans in private conversations due to the minimalist and unconventional nature of its chat tools.

Well Suited for:
  • Creating a private Chat room, sharing confidential data, allowing modifying/ deleting or updating previous messages.
  • Securing data and important notes used in a group chat or private room
  • Managing Messaging Thread
  • Sharing important documents and images

Bringing a more social touch to everyday business

Vetted Review

Likelihood to Recommend

Slack is a great tool to facilitate communication in large and small enterprises alike. Having the ability to send quick messages to colleagues around the world without the formality of an email makes communication more efficient. The emojis and gifs also bring a bit of whimsy into the office which in turns makes for a more comfortable office atmosphere. For a remote workforce, this tool makes staying in touch and communicating much easier while providing a helpful social aspect, after all there is no water cooler to gather around. For smaller businesses and non-distributed teams, it is still a valuable tool to keep track of and share information but definitely not a necessity.

Slack... One-stop solution for business communication

Slack is really helpful when we need to discuss anything with team members. We can ping them or can Audio/Video call as well. This provides screen sharing feature as well. In channels we can tag right person for any relevant task, I personally like that feature. But still some improvements are required like we cannot schedule future calls here although we can integrate Outlook calendar plugin, the second one is, in screen sharing we cannot pass controls access to other person like Teams or GoToMeeting.

Slack is a solid group-communication platform. Clean, easy, intuitive. Offers a rich feature set and integrations.

Slack is fantastic for real-time info sharing, wide dissemination, and soliciting fast responses. It is very easy to create channels and groups, enabling a user to route info effectively or communicate in a targeted fashion; it is also seamless to create side channels. Slack is great at integrating various media forms brilliantly in a clean UX.

It is not as great as a structure, prioritization, tasks, workflow, etc. It is also not easy to categorize various topics in a channel for easy reference and retrieval.

It is an excellent communication tool. It is especially useful for a remote office. The screen sharing is very well implemented. VOIP quality is also good. In many ways it will replace long email strings and dedicated voip systems for inter office communication. The app marketplace also allows for a variety of plugins that can connect slack to tools like the g-suite and salesforce.

When there's a team that spans time zones and continents, Slack is the perfect tool for communication & collaboration. It houses a workplace directory, so any employee can be searched for by name. Sending a direct message to any individual in the company is as simple as finding their name, then typing a message & hitting send! Essentially, it's a hub for all communication -- individual, team, and company-wide announcements can be quickly & easily disseminated using Slack.

On the Slack Line: a Fun and Balanced Communications Tool

Slack is great when you have a working group that is spread out over various locations; beyond facilitating productive chat sessions -- as well as video conferencing and screen sharing (depending on your pricing tier) -- Slack's fun features can really help to build team camaraderie.

Slack may not be a great fit for working groups that prefer face-to-face communications, or those teams that are already well-acclimated to another group chat tool.

Scenarios where Slack is well suited:
  • Distributed teams and/or companies with multiple offices.
  • Startups: Helps new employees get a quick view of the "bigger picture" -- everything that's happening inside the organization.
  • Teams that need real-time communication to run their operations (eg. customer support, engineering).

Scenarios where Slack is less appropriate:
  • Large organizations with several hundred employees if not managed correctly -- it can add too much noise/distractions.

The ability to collaborate between multiple teams including customers and clients is a superb pro feature when dealing with Slack and it's a scenario where we find Slack to be useful.
However when it comes handling a video call where multiple people speak and they are sharing the video and also want to share the screen or maybe request access to control the desktop, Slack needs improvement and it's less apt.

I think Slack is a really good product for organizations of all sizes. It works for startups and big corporations alike. Since it can be expensive according to the plan you choose, it is really important to make sure you take full advantage of its functionalities and not use it only as a chat software, since there are cheaper alternatives for that.

Great for any business that needs more immediate communication than email provides. Well suited for business where workers don't work in the same room, e.g. remote workers. Slack can make it almost as good as if everyone were in the same room.

It's less well suited for serious conversations and again can hinder productivity if people start losing their focus on their project just to answer every little message.

Slack is very well suited if you have employees situated at different places or offices, especially if some employees have to go out for field work. It's very easy to update the task or work done remotely using Slack's mobile app. Slack doesn't seems to be useful in cases of full professional needs, as it lags in many ways in comparison to its competitors.

Slack would be well suited if you had a development team in Mongolia and another one in France and they did not have to talk to each other a whole lot. Slack would be a good record of fact on what might be going on between the groups. It can keep track of things, almost like a log of human interactions.

Slack maintains team communication focused on a single space. Productivity is greatly improved because integrated applications are kept in one place, which avoids distractions. It is great for digital work environments.
For occasions when you have to talk to staff who do not work in the digital areas, it is equally helpful. With the integrated Dropbox functionalities, you can share files referring to the important documentation of everyone in the company. It is not appropriate to use Slack without making the purchase of the paid license. The definitive limitation is that the free version has a limit of messages that can be saved, which includes the files that are sent.
