Streamlining and simplifying team communication
(359 Ratings) Write Review

Slack is a communications and workflow solution designed for teams. Using Slack, you can set up channels, which can be around any theme, project, client or department. You can invite people to join these channels, or make them private, and people can leave whenever they want. With Slack’s search functionality, you can quickly skip to past communications. You can also star conversations to add them to your favorites, and allow you to quickly access them again in the future. Slack threads allow people to carry on the conversation in a separate place, rather than cluttering up the channel with their responses. With Slack, you can share PDFs, images, videos, and gifs, and you can mention one individual or multiple people within channels to get their attention. You can also direct message people when you want to have 1-2-1 conversations, and quickly add more people to that conversation if you need more opinions.

Slack has been super useful for my team's collaboration, and it's not slow and laggy like Skype.My only complaint is when adding workspaces to the Slack app, and switching between a web browser and a native app, it's a confusing process.

"The communicational application that has been able to unite my staff"

What do you like best?

I like to use this system a lot because it is lightweight and can be used on any device. Allowing a greater integration in my work team. This system is much more versatile than any other on the market, in which I can easily send any type of files privately or in groups without increasing the storage capacity of the system.

With Slack one can perform any type of work not only by chatting but also by means of a video conference, it must be taken into account that all documents shared as conversations have an expiration period that in a certain time the most complete algorithm that has Slack is responsible for cleaning the system.

What do you dislike?

Something I do not like at all about slack is that when I chat with my team of managers who in themselves are more than 15 the system tends to fall and in turn to use many resources of my servers, slowing down all the process of my business. This is definitely a headache.

Recommendations to others considering the product:

I can definitely recommend this system because it is very flexible and is capable of giving it that integrating drive that every business needs.

What problems are you solving with the product? What benefits have you realized?

To be able to count on a system like slack is without a doubt the best thing that has happened to my business, since one enters you feel the sense of belonging of each member of my work team, thus granting a positive increase in the organizational climate. I have also noticed that the processes have been completed before the delivery times, allowing to give productivity bonuses to my staff that really deserve that and more. Also my business has experienced an increase in productivity thanks to this program.
