The work you build is only as good as the utility people get from it.
Utility is another word for value.
Think of music. How much of the same artist can you listen to before you need to change to something new? That time frame could be a representation of utility.
Think of coffee. How much coffee would you drink before you say "okay, that’s enough coffee”? That number could be your max utility.
Now imagine - if you had the choice to between listening to the same artist for a length of time or having coffee, which might you choose? And which would you gladly have more of? That’s another way to talk about utility.
In terms of our work - what utility do people interacting with our work get? What do they want more of? What do they get enough of? Which aspect of our work do they prefer?
If living is a work, that work ought to create value for those we seek to serve.
