Defining chores
Include all shared responsibilties
Include everything that you want to be recognized for. Even small tasks can be meaningful.
Exclude all personal tasks. Cleaning your room might be a duty, but it's not a shared responsibility.
Group chores
Try to include chores that your team can do together. For example, shopping for groceries and putting groceries away are two great tasks for the whole team.
Give full points to everyone that participates. It might slightly dilute points, but the overall effect is very positive.
Make chores discrete
Avoid lumping several related chores into one chore. For example, "yard work" might be better expressed as "mowing the lawn", "raking the leaves", "weeding" and "trimming".
This allows multiple people to contribute. Even if one person does all the work, it's more satisfying to check off several chores.
Embrace variations
The same type of chore can have different values.
For example, making dinner. There is a big difference between heating frozen lasagna and making something from scratch.
It's fine to have one chore for "basic dinner" and another for "very fancy dinner".
Specialist chores
Some chores can only be done by certain team members.
It's fine to have an understanding that "only dad is crazy enough to get on a ladder and clean the gutters", but try to maintain agency.
These treat these chores as any others. Debate and tweak the points as a team.
Consider allowing others to assist, and let them earn bonus points.
