Material Requirements Planning is one of those terms that sounds like it belongs in an enterprise software brochure. In practice, it answers one simple question: do we have enough material to make what we need to make, when we need to make it?
The answer depends on how far ahead you're looking.
The 7-Day Horizon: Tactical
The 7-day horizon is your immediate operational window. What production orders are confirmed for the next week? What materials do they require? What do we have on hand? What's already on order and expected to arrive in time?
At this horizon, the answers should be precise. If there's a shortfall, you need to know today - because lead times for emergency procurement are measured in days, not weeks.
The 14-Day Horizon: Transitional
Two weeks out, you're looking at confirmed orders plus high-probability demand. This is where procurement decisions happen. If a raw material has a 10-day lead time, the 14-day horizon is where you catch the gap before it becomes an emergency.
FalOrb's MRP engine cross-references production order schedules, current stock levels, incoming purchase orders, and BOM requirements to surface shortfalls at this horizon - automatically generating purchase recommendations with suggested quantities and timing.
The 30-Day Horizon: Strategic
At 30 days, you're planning capacity. Which production lines will be busy? Which suppliers need advance notice? Are there seasonal patterns that require building safety stock?
This horizon is less about individual orders and more about aggregate demand across product families. It's where you negotiate supplier commitments and plan labor allocation.
The 60-Day Horizon: Structural
60 days out, you're looking at supply chain resilience. Are you over-dependent on a single supplier for a critical raw material? Do your lead times create structural bottlenecks that no amount of tactical management can solve?
This is the horizon where you make decisions about:
- Alternative suppliers for single-source materials
- Safety stock policies for high-variability items
- Production line configuration for upcoming demand shifts
- Supplier negotiations based on volume forecasts
The Compounding Effect
What makes MRP powerful isn't any single horizon - it's the layered view across all four. A shortfall that appears at 60 days gives you time to source alternatives. The same shortfall discovered at 7 days gives you time only to scramble.
The difference between proactive and reactive procurement is simply how far ahead your system can see.
FalOrb provides MRP planning across 7, 14, 30, and 60-day horizons with automatic purchase recommendations based on production schedules, BOM requirements, and supplier lead times.
