Does that couple also work at the same company as product managers?

I find in this situation that new member onboarding can unfortunately take years

I worked with a sysadmin that did this for his kids, and even moved chore assignments around automatically based on grades (which he scraped from some school portal). Get a D and you'll have to do your sister's chores!

My wife and I use Trello for stuff like this. Though the main use case is as the world's most reliable checklist-syncing program for grocery shopping. The task tracking is also nice

Digital list with checkbox is not inherently evil
