What Is Supply Chain Planning?
Supply chain planning is the process of coordinating all activities required to source, produce, and deliver products to customers — from raw material procurement through manufacturing, warehousing, and last-mile delivery. It bridges demand planning (what customers will buy) with supply management (what can be produced and when).
Core Components of Supply Chain Planning
Demand Planning
Forecasting what customers will buy, when, and in what quantities — the starting point of all supply chain planning.
Supply Planning
Determining how to satisfy demand: which suppliers, what quantities, and what lead times. Includes purchase order management.
Production Planning
Scheduling manufacturing capacity to produce the right products at the right time. Includes capacity constraints and production calendars.
Inventory Planning
Deciding where to position inventory across the supply chain (supplier, 3PL, distribution center, store) and at what quantities.
Transportation Planning
Optimizing inbound logistics (freight, lead times, port routing) and outbound fulfillment (carrier selection, zones, routing).
S&OP (Sales & Operations Planning)
Monthly executive process that reconciles demand plans with supply capacity and financial targets across the organization.
Lead Time Management for Importing Brands
For brands sourcing from Asia (China, Vietnam, Bangladesh), total lead time from PO placement to warehouse receipt typically ranges from 60 to 180 days, including:
- Supplier lead time (Cut-to-Ship) — 30–90 days from PO to ex-factory
- Transit time (Ocean Freight) — 20–45 days depending on origin port and destination
- Port clearance & domestic freight — 5–15 days after arrival
This means demand planning must be accurate 3–6 months in advance. Integer Demand's Inventory Projection table gives you a week-by-week view of projected stock levels, committed purchase orders, and lead time-adjusted arrival schedules.
Supply Chain Risk & Resilience
- Single-supplier risk — Diversify across suppliers or countries for critical SKUs.
- Lead time variability — Buffer with safety stock calculated for lead time uncertainty, not just demand variability.
- Port disruptions — Maintain 8–12 weeks of safety stock for A-class items imported by ocean.
- Demand spikes — Pre-build inventory before peak periods using demand forecasts with promotional lift.
