At my office, we use Slack and Teams, but honestly no one actually checks a digital status before they walk over to your desk.
I keep a QR code on my desk with a note that says "What I’m up to." Anyone can scan it to see if I’m in a deep-focus session or free to chat. I can update it from anywhere just by sending a quick email to a custom address. (There is a 'Download QR Code' icon on the page to make this easy).
I’ve also started putting the link in my email auto-replies. Standard OOO messages are usually static and boring, but this makes them a bit more dynamic/useful.
You can use it for all sorts of things, like notice boards etc. You can create up to 2 pages per email address.
I’m curious to know if you find this useful or how you’d use a simple status page like this. Thanks!
