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.
