YNAB: where money is kept and what it is for are different questions
YNAB helps people give the money they already have a purpose. Accounts show where it is kept; categories show what is reserved for rent, food or later needs. Both views describe the same funds.
Form your own approach first, then explore the reasoning to check trade-offs and validation you may have missed. There is no single right answer.

DESIGN QUESTION
Forty workshop hours are available. Why is the plan still in conflict?
A community workshop has two rooms, each available for 20 hours next week. The organizer has promised 16 hours for newcomers and 24 for experienced members preparing an exhibition, without assigning rooms yet. Only Room A has ventilation. Experienced members need 18 of their hours there; newcomers would like 12 hours there to try spray painting.
- Design a process that takes the organizer and participants from “reserving time for a purpose” to “booking a specific room.” Decide when a reservation is an intention and when it becomes a commitment, who can adjust it after a conflict, and how people learn what they gain or lose. Deliver a usable process and a sample weekly schedule.
- Work through the figures: why is there a conflict when the total 40 hours appears sufficient? Produce a feasible final schedule using your process and explain who bears the cost. Propose an observation metric to detect whether users mistake a purpose reservation for a confirmed room booking.
Explore the reasoning
- Draw room capacity and purpose commitments separately. First calculate the actual demand on Room A.
- Compare changing the introductory activity, reducing hours or changing when commitments become firm. Preserve the consequences each participant needs to know in advance.
- Check the final schedule against both room capacities and purpose commitments. Ask participants to describe their arrangement to test whether they understand its current stage.
