MB-330 Implement Master Planning Practice Question
A company uses a 'Period' coverage group. How does the planning engine determine the quantities for replenishment?
⚠ Common exam trap
Many candidates mistakenly believe a period coverage group creates daily separate orders, confusing it with requirement coverage instead of recognizing its demand aggregation mechanism.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
It aggregates all requirements within the period into a single planned order.
Period coverage groups consolidate demand occurring within a defined period into a single planned order. This strategy is essential for reducing the number of orders and optimizing shipping costs. By grouping requirements, planners can align procurement with logistical efficiencies, such as full truckloads, which is a common requirement in supply chain optimization where minimizing the frequency of orders is as important as the items themselves.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
It aggregates all requirements within the period into a single planned order.
Why this is correct
The period coverage group consolidates multiple individual demand requirements that fall within the same defined period, such as a week or month, into one cumulative planned order. This approach simplifies procurement by reducing the administrative burden of managing multiple small orders and helps in optimizing logistics and shipping costs.
- ✗
It creates an order for every single demand requirement regardless of timing.
Why it's wrong here
Creating an order for every individual demand requirement is the behavior of the 'Requirement' coverage code, not 'Period'. This would lead to a high volume of small, inefficient orders, which is the specific scenario that the period coverage group is designed to prevent by consolidating requirements.
- ✗
It uses the minimum inventory level to trigger replenishment only.
Why it's wrong here
Using minimum inventory levels as the sole trigger is indicative of the 'Min/Max' coverage code. While period coverage considers requirements, it does not prioritize inventory thresholds in the same way, focusing instead on the temporal aggregation of demand requirements into consolidated supply orders over a specific timeframe.
- ✗
It ignores all demand outside the immediate planning time fence.
Why it's wrong here
The planning time fence dictates how far into the future the system calculates requirements, but it does not determine the method of replenishment aggregation. The period coverage logic remains valid as long as the demand falls within the planning horizon, regardless of the specific time fence settings.
