How do you prioritize when everything seems urgent?

Discuss risk-based prioritization using customer criticality, revenue, and lead-time impact.

What motivates you in a planning role?

Link motivation to solving complex problems, enabling on-time delivery, and improving systems.

Share a failure and what you learned.

Focus on root cause, corrective actions, and how you updated standard work or parameters.

Why should Cummins choose you for this role?

Summarize role-aligned strengths: PFEP, master scheduling, KPI governance, and collaboration.

Use the STAR method and quantify outcomes to make your examples memorable.

Technical and Industry-Specific Questions
Explain the difference between MPS and MRP.

MPS sets the build plan for finished goods; MRP explodes requirements to components and raw materials.

What is PFEP and why is it critical?

PFEP defines part-level parameters (lead time, MOQ, safety stock, packaging) that drive accurate planning signals.

Which KPIs would you track in planning at Cummins?

Forecast accuracy/bias, OTIF, plan adherence, inventory turns/DOH, lead time, past-due, expedite rate.

How do you set safety stock levels?

Use demand and supply variability, service targets, replenishment frequency, and lead-time uncertainty.

Describe time fences in master scheduling.

Frozen, slushy, and liquid zones govern changes to protect stability while allowing controlled flexibility.

How do engineering changes (ECNs) affect planning?

They trigger effectivity dates, phase-in/phase-out strategies, and risk of obsolescence requiring control.

What is capacity-constrained planning?

Aligns plans to finite capacity, sequencing to avoid overloads, using RCCP/CRP and constraint buffers.

Explain S&OP’s link to MPS.

S&OP sets aggregate demand–supply balance and inventory strategy; MPS operationalizes it at SKU level.

How do you manage long-lead items?

Early visibility via forecast, strategic buffers, supplier collaboration, and milestone monitoring.

When would you use pull vs. push systems?

Pull (Kanban) for stable, repeatable demand; push for variable demand or long, complex BOM structures.

Ground your answers in first principles, then add examples and metrics from your experience.

Problem-Solving and Situation-Based Questions
Demand spikes 30% for a key product what is your response?

Assess capacity, critical components, supplier flex, and propose phased commits with risk buffers.

A supplier indicates a two-week delay on a long-lead part. Next steps?

Run impact analysis, re-sequence builds, explore expedites/alternates, and align customers on recovery.

Inventory is rising but service is falling. How do you diagnose?

Check demand mix shifts, parameter drift, forecast bias, and constraints causing misallocation.

How would you execute an ECN without disrupting production?

Define effectivity, deplete old stock, dual-run if needed, and lock schedules within time fences.

Two plants compete for a scarce component. How do you allocate?

Use customer priority, revenue/penalty risk, and plan adherence; communicate decisions transparently.

What if forecast accuracy drops below target?

Segment SKUs, identify bias, tighten collaboration with Sales/Marketing, and recalibrate safety stocks.

Logistics lead times increase unexpectedly. Mitigation?

Adjust PFEP lead times, re-plan buffers, consider mode shifts, and update promise dates.

Plan adherence is low on a key line. What’s your action plan?

Root-cause via downtime, changeovers, material availability, and stabilize with finite scheduling.

New product ramp coincides with peak demand. How do you plan?

Scenario plan capacity, staged ramp, pilot builds, and protect legacy demand with time fences.

How do you decide between expediting and backordering?

Compare customer impact, cost-to-serve, SLA/penalties, and long-term precedent; escalate per policy.

State assumptions, outline options, pick a recommendation with quantified trade-offs.
