Chat (such as Slack) is far superior to other modes of communication. Only in person or video communication is more efficient, but even for that Slack is a good way to initiate since it is less interruptive. Some of the points in the article actually highlight reasons why chat is better: They promote a false sense of urgency This is very much a culture thing. You can always vary the communicated urgency by e.g. saying "when you get the chance" vs. @-mentioning people. Importantly though, when you do need a reply soon, Slack is much better at getting that. They destroy focus The article mentions paranoid checking. My experience is the exact opposite - with async tools (e.g. email, task manager, google docs) I find myself paranoidly checking / browsing to make sure I'm not missing anything. With a tool like Slack, it's easy to know when I've read everything (or read everything in channels that matter), and don't need to keep paranoidly checking because I'll get a notification for important stuff. They allow for bypassing project prioritization ... ALL WORK, including troubleshooting issues, fixing bugs, and answered questions should go through the Product Owner. That's ridiculous. You shouldn't have to go through a high overhead prioritization process just to do some quick work. Sure, put it in prioritization / whatever when you realize it's a big piece of work and / or needs to be kept track of, but don't take away the ability to get things done quickly without having to go through a burdensome product process. They strip away essential business context Feature, not a bug. You can always link to extra context, but often the concise nature of chat forces people to use tl;dr which results in far more efficient communication for the reader. They encourage poorly thought-out communication Again, feature not a bug. Lots of brief communication is far better than a few carefully drafted essays. Well written communication requires a lot of time and effort to write, and people don't need that overhead to get on the same page, which is the point of internal communication.
