Resource Systems

Distinguish resource categories while locating their connections.

Separate owning a product from the function it delivers.

Follow a resource beyond the place where it is purchased.

Compare who obtains services and who experiences extraction or waste effects.

Convert quantities only with the required density or energy information.

Distinguish material present from material entering per day or year.

Record method, timing and precision along with the result.

Separate missing observations from measured zero.

State which places, activities and period the record covers.

Use input minus output equals stock change for a conserved material.

Track an element when products change chemical form.

Investigate unexplained differences instead of labelling them disappearance.

Use paper sheets for a shared printing task or another accessible known material.

Count entering sheets, useful output, rejects and remaining stock over one period.

Find missing transfers and compare resources per completed task.

Test a justified setting or process change and repeat the same service comparison.

Label what each node, connection and stored quantity means.

Reconcile numerical records before drawing widths.

Compare widths only when the same unit and scale are used.

Separate internal transfers from inputs crossing the outer boundary.
