ECO.1:5 - Archetypal Grounding

ECO.1:5.1 - A cheap plan priced in internal credits

In a constructed repair-depot case, purchasing a compatible part costs €90 delivered this week. A spreadsheet values making it internally at 40 machine credits plus €30 of material. It silently treats a credit as a euro, although credits allocate booked machine time and cannot purchase extra time. The machine has no available slot this week.

The practitioner removes the unsupported €70 comparison. A nearby provider offers the required machining this week for €65, using the depot’s €30 material. The usable comparison is therefore €95 for that route against €90 for the delivered part, subject to equivalent fit and warranty. If no matching offer exists, the internal-credit plan remains unavailable this week; solving its allocation model again cannot make it available.

The repair does not reject credits as a scheduling aid. It stops a claim about monetary cost and availability that the credits did not support.

ECO.1:5.2 - A choice without a market quotation

A community can repair one of two paths with the same already available volunteer time. It has no defensible monetary value for each improvement. The group can still choose by access needs and the repair each alternative permits. Reporting that choice as a financial return would add an unsupported claim; postponing it until every benefit has a price would add unnecessary work.

ECO.1:5.3 - A useful marginal value inside a model

A workshop has ten usable machine-hours and demand for up to twelve identical one-hour jobs. Each completed job contributes €30 after the other relevant variable costs; the remaining inputs and commitments permit any of these jobs. The model’s best contribution rises from €300 at ten hours to €330 at eleven and €360 at twelve. A thirteenth hour adds nothing under that demand limit.

Thus €30 is the modeled value of each of the next two usable hours. It helps set the terms worth considering: an available matching offer at €20 per hour would leave €10 more per added job. The modeled value itself does not supply that offer or make another operator available. A changed demand limit, job mix or needed complement requires a new calculation of the affected margin. The workshop can keep the conditional comparison without investigating every possible capacity supplier.
