Every company you have ever worked for has an operating system. Your home almost certainly doesn't.
Most homes run on a combination of habit, improvisation, and whoever happens to remember. The grocery run happens when the fridge empties. The AC gets serviced when it stops working.
What a Home OS looks like
A functioning Home Operating System has four components: a single source of truth, scheduled recurring tasks, a clear owner for every task, and a weekly review.
The most sustainable shortcut is a person who owns the system on your behalf. Your Lifestyle Manager is, in effect, your Home OS made human.
