Some good answers here already, it’s great to have a community like this.
Something that’s extremely helpful that I don’t see mentioned yet is using screencasts — this has been crucial in my own business and in consulting clients on collaboration it’s often overlooked.
The best intentions for communicating via text can go sideways if you and the other people on the Task aren’t fully on the same page. Sure, you could setup time for a meeting to go over those things together with screensharing or in-person but many times a quick screencast (or a good screenshot with annotations) can do wonders for communication.
There are some great tools out there to make this easy, a popular one recently is Loom if you’ve never tried screencasting to add valuable info to a task — I highly recommend trying this out. What’s different about Loom is that it uploads the video while you are recording so as soon as you are done it’s ready to send, that makes it very convenient. (No I don’t work for Loom, I actually use other tools personally because I’ve been using them for a while but for new users I almost always recommend Loom now because it’s so quick and easy to get up and running).
Other tools I use are https://screencast-o-matic.com/ (great for longer training videos because there’s some advanced editing features), Screenpresso.com (I like this one because I can upload to my own custom domain for sharing) but it’s only available for Windows.
