Slack Overview

What is Slack?

Slack is a workplace communication tool that connects users with the people and tools they work with everyday, no matter where they are or what they do. Teams in Slack work together in channels that can be organized by project, department, office location, or anything else, really. This makes it easy for users to follow the topics that are important to them. Public channels are open to anyone on the team so marketing can see what designers are working on, sales can see what’s on the product team’s roadmap, and new hires can easily get up to speed instead of starting with an empty email inbox.

Slack connects to the tools and services that businesses already use and centralizes the notifications, files, and data from hundreds of different applications. This means no more searching through emails for that one follow-up, constantly switching between different tabs and dashboards, or juggling dozens of tools - each with their own login. Slack helps teams work smarter by providing all of the information and context needed to make effective decisions quickly.

Everything shared in Slack is automatically indexed and archived so that companies can create a comprehensive knowledge base with zero effort, simply by working in Slack. And, Slack’s search makes it easy find the information users need, whenever they need it.

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.

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.

Great for charitable organizations (because it can be free). Powerful. But expensive!

Push notifications and alerts have been helpful. We are able to get important information out to our team very quickly, and we are able to "thread" the information so that only certain groups or certain topics are discussed in certain "channels" or "threads."

Slack is essentially advanced texting for business users

I started using Slack because my client required it. I find that it cuts down on my email dependence but I'm often frustrated when attempting to compose a message without standard elements such as tables, inline images, etcetrera.

One of the Best Collab tools!

Overall the tool is used to communicate and share files amongst your own team as well as other teams which are external to yours. Its great for announcements or even details that you can pin to each individual or team chat. The channels allow you even finer controls over who can see it, participate, as well as the overall purpose. Its a superb tool for having each team create their own channels as well as special channels which can be used for announcements, heads up, changes, basically anything you need to communicate across. It is everything you would expect in a collaboration tool.

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.

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.

Pros

Slack is made free for basic functions for charitable organizations. For this reason it can be a great option for charitable organization. It has powerful features, including video conferencing, file sharing, phone and web app integration, and file sharing. It also has cross-platform integration allowing connectivity between multiple different products, including Google and Microsoft products and IFFFT.

Cons

It is not cheap at all for even a small organization (unless your organization qualifies for a free subscription). There are limits to the number of users in a video conference.

I started using Slack because my client required it. I find that it cuts down on my email dependence but I'm often frustrated when attempting to compose a message without standard elements such as tables, inline images, etcetrera.

Pros

I like the ability to stay in touch with our users via whatever device I'm currently using. For example, I can respond from my home computer, tablet, work computer or via my phone.

I especially like the ability to be notified of a new message via my phone where I can read the message on the phone but can step over to my laptop to reply.

I also appreciate the ability to add an email thread to a Slack Channel by simply adding a slack email address (each channel has a unique email address) to the CC field when I reply.

Cons

The biggest con for me is the extremely limited amount of formatting available to Slack messages. I can make a font bold and add links to files/images but I really miss the rich text features many similar apps provide.

It's also frustrating to need to keep typing adding the user name(s) when I'm responding to a message. I'm assuming that this is by design but it would really be nice to be able to "Reply All" to a conversation thread.

The desktop Slack application (running on Windows 10 Pro) has a "clunky" feel to it. It's written with a framework that allows the Slack developers to write HTML and JavaScript code that is essentially compiled into a Windows application and it definitely shows. Something as simple as selecting text is counter-intuitive (until you realize that it's essentially a web page mascaraing as a Windows application.

Pros

Ease of use and the feature list is probably why this tool does so well. It even allows you to build custom apps that you can implement with your existing apps/tools for a more streamlines experience! Its honestly made life a lot easier to collaborate amongst team members, especially during Corona times and working from home.

Cons

There really isn't much about this tool that I don't like. It runs smoothly and constantly has new updates to make the experience even better. The only thing I can think of is that it can be resource intensive at times but honestly it has not slowed me down yet. Also, when sharing your screen with another team or individual, you have to go back to the initial chat to send a message, it would be nice if it can be done from the same UI of the screen-share. Well made tool overall!
