OPS.8:4.3 - State what each buffer protects
Select only the protection needed for the operating question.
| Arrangement | What its policy controls or protects | Useful quantity |
|---|---|---|
| ready-work buffer before a selected service | service continuity during replenishment delay | eligible service load, related to the resource’s operating calendar |
| inventory reserve | availability of specified material under replenishment and consumption uncertainty | usable quantity by material, location and condition |
| capacity reserve | response or recovery when load or availability changes | usable resource time with the necessary capability and access |
| limit on started items | congestion and exposure from concurrent unfinished matters | items under an explicit start/finish boundary, with load differences retained |
For the selected arrangement, state the shortage or disturbance, the consequence of failure, who replenishes it, what consumes it, and what signal changes action. A customer’s commitment has its own parties and conditions; it does not automatically put the item in a protective buffer.
