The Business Communication Tool of it's Time

Honestly, this software just doesn't have competition at it's level and they have a stranglehold on this market, as they deserve. Between Spark, Skype, and Hangouts, they're really the Nickelodeon to Disney. Although they'll stick around, with the ability for them to add so many integration possibilities by not only their own development but other companies wanting to allow their own software's workflow to somehow run through Slacks platform. It's just a simple platform with so many functionalities and possibilities.

Pros

Availability. Simplicity. Instant transferability between devices. Customizability (yes, it's a word). One of my favorite pieces though is the ability to integrate so many other applications into and out of it. Get to that more in a moment...

Cons

This is petty but one of the largest issues I run into is when in the office and have Slack running on both my iPhone and my MacBook, sometimes I miss important, timely messages due to device priority. If the laptop screen is still open and I'm only a room or two over in another meeting, my phone will not receive the messages from the laptop until my screen times out and the rests.

Reasons for Choosing Slack

The overall span of functionality just trumps all other. As a software company, with the ability to run so many planning, tracking, and actual development applications through Slack, it allows for so much coordination and management directly from your office seat.

A good product with potential

Overall, my experience has been positive. As mentioned, there are many aspects that are very easy to use. Slack works well for our management team who is always active on it and focused on certain projects. However, for our general customer service team, it is less effective.

Pros

I like how easy the software is to use. It's very intuitive for anyone who has used a messaging app before. Another feature that is valuable for us is the ability to add employees to only certain channels. We have a diverse team that doesn't need to be involved in every conversation.

Cons

I wish that some of the pro level features were available for the free version. It is cost prohibitive for us to pay for the pro version. For example, we often run into an issue when trying to search for things that are far back in a channel. Slack only allows us to go back so far. Therefore, we lose important communication. Also, the nature of the Slack channels allows things to get easily lost. As team members, comment and change the subject important pieces of information get buried before everyone sees it.

Reasons for Choosing Slack

Asana was too feature-rich for us and seemed hyper focused on project management. We wanted a program that is easy to use and also serves as a simple communication tool.

Slack is the backbone of what we do

Slack is used by everyone in the business on a daily basis, it allows us to work efficiently and makes working remotely a breeze.

Pros

There are other products out there that provide a similar service, but for me nothing compares to slack's flexibility to integrate with the other online services we use and automate workflows and reporting.

Cons

The video call feature could do with some slight improvements, a grid view would be great for group calls for instance.

Reasons for Choosing Slack

Integrations were high on our priority, but also ease of use and the ability to easily add external companies into shared channels.

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.

The best chat and communication tool for teams

Its great when everyone is in a single location and you can just walk up and ask your questions face-to-face. This isn't the case for most of us anymore as we are working with remote teams and different schedules. Slack has made communication almost as efficient as face to face. You can even reach people on their mobile devices after hours if needed. The ability to connect all of this communication with many of our other products and services just makes it even better.

Pros

The interface is the best we have used and is easy to navigate and understand. Channels make a lot of sense and everyone using Slack seems to understand how they work. Tagging others in a conversation is a great way of calling attention to the specific people who need to see a message. Integrations work well and there are already a lot of them but making custom integrations is also easy.

Cons

I wish there was some better way of organizing tons of channels. This is probably not a big deal in most places and you can hide everything but the channels that you want to see but some better hierarchy like folders or something like this would be great.

Reasons for Choosing Slack

We like Slack's more independent brand and the overall design feels powerful and light at the same time.
