FREE CSCP Study Guide 2026: All 8 Domains

This free CSCP study guide walks through everything the ASCM Certified Supply Chain Professional exam tests, organized to ASCM’s current Exam Content Manual.^[1]

It’s interactive, not a wall of text: every domain has built-in checkpoint quizzes, flashcards, and practice questions, so you learn by doing — not just reading.

The CSCP is the end-to-end global supply chain credential from ASCM (formerly APICS). It covers the whole chain from the supplier’s supplier to the customer’s customer — distinct from the CPIM, which focuses on internal manufacturing planning and inventory.^[4]

The current exam tests eight official content domains, each carrying a published weight — Source Products & Services (17%), Internal Operations & Inventory (19%), and Customer & Supplier Relationships (17%) together are over half the exam.^[1] We teach one module per domain (after a short Foundations module), combining the two smallest domains (Risk and Evaluate/Optimize) into the final module. Read a module, test yourself at each checkpoint, then drill gaps with our free practice test and flashcards.

CSCP Exam Snapshot

Study by weight. The three biggest domains — Internal Operations & Inventory (19%), Source Products & Services (17%), and Customer & Supplier Relationships (17%) — make up 53% of the exam, so that’s where most of your time goes. The two smallest, Logistics (9%) and Evaluate & Optimize (8%), are still high-yield and quick to learn:

Foundations · The End-to-End Supply Chain

Before the eight domains, get the big picture straight — because every CSCP question assumes you understand what a supply chain is, how it creates value, and how strategy drives every design and sourcing decision. This short module is the scaffolding the rest of the guide hangs on.

What a supply chain is & how CSCP frames it

A supply chain is the global network used to deliver products and services from raw-material sources to end customers, through an engineered flow of information, physical goods, and cash.^[1] Supply chain management is the design, planning, execution, control, and monitoring of those activities to create net value and synchronize supply with demand. The CSCP’s defining feature is scope: it spans the whole chain, from the supplier’s supplier to the customer’s customer — which is exactly what separates it from the internally-focused CPIM.

Strategy, order winners & the SCOR model

The supply chain exists to support how a firm chooses to compete. order qualifiers are the minimum traits a product must have to be considered; order winners are what actually make a customer choose it. A supply chain is designed to be efficient (low cost, for stable functional products) or responsive (fast and flexible, for uncertain innovative products) — and the chosen total cost and service trade-offs flow from that strategy.^[1]

To describe and improve any supply chain, ASCM uses the SCOR model — the Supply Chain Operations Reference model — built on six core processes: Plan, Source, Make, Deliver, Return, and Enable.^[2] It is the backbone framework that runs through the whole exam, and its performance attributes (reliability, responsiveness, agility, cost, asset efficiency) define how supply chains are measured.

Domain I · Forecast & Manage Demand (10%)

10% of the exam. This domain is about understanding demand, predicting it, and aligning supply to it. It covers demand analysis and patterns, building and grading forecasts, and the cross-functional process — S&OP — that reconciles demand with supply.

1.1 Demand analysis & forecasting methods

demand management starts by recognizing all sources of demand and analyzing patterns — trend, seasonality, and the product life cycle. Firms also shape demand through the marketing mix (the Four Ps: product, price, place, promotion).^[1] Then they forecast. There are two families of method:

1.2 Forecast accuracy, S&OP & the bullwhip effect

Every forecast is wrong — the question is by how much. Measure error with Mean Absolute Deviation (MAD) and MAPE, and watch the tracking signal for bias (a consistent tendency to over- or under-forecast). Forecasts are also more accurate at an aggregate (product-family) level than at the SKU level, because individual item variations partially offset — the same risk-pooling logic that justifies postponement and centralization.^[1]

Demand and supply are reconciled through sales and operations planning (S&OP) — a cross-functional process that balances aggregate demand against capacity, inventory, and the business plan, and ends in an executive review that commits the organization to one number.^[1]

The classic demand pathology is the bullwhip effect: small swings in end-customer demand amplify into ever-larger order swings upstream, causing excess inventory and stockouts. Its causes are demand-signal processing, order batching, price fluctuation (forward buying), and rationing/shortage gaming — and sharing real demand data, often via CPFR, dampens it.^[1]

Domain II · Manage the Global Network & Information (10%)

10% of the exam. This domain is about designing the supply chain network and running the information that connects it — configuration, visibility, data, metrics, and the technology that makes it all work.

2.1 Network design, push/pull & postponement

Network design decides the number, location, and capacity of facilities and the flows between them, balancing cost against service.^[2] A central design choice is the push-pull boundary: upstream activity is push (forecast-driven, make-to-stock), and downstream activity is pull (demand-driven, make-to-order).

postponement delays final differentiation until demand is known, moving the boundary downstream and pooling risk — so a firm holds generic product and customizes late, cutting finished-goods inventory and obsolescence. Centralizing inventory does the same thing geographically (risk pooling).

2.2 SCOR, metrics, data & technology

The chain runs on information. End-to-end visibility and connectivity let partners see real demand, inventory, and shipments; master and transactional data must be created, cleansed, and governed across its lifecycle.^[2] Performance is tracked with metrics — the SCOR perfect order fulfillment (complete, on time, damage-free, correct documentation), cash-to-cash cycle time, inventory turnover, and a balanced scorecard that spans financial, customer, process, and learning views.

Domain III · Source Products & Services (17%)

One of the three biggest domains — 17% of the exam. This domain covers how an organization decides what to make versus buy, builds a sourcing strategy, selects and contracts suppliers, and manages the purchase orders that follow.

3.1 Make-or-buy, strategic sourcing & category strategy

Sourcing begins with the make-or-buy decision — produce in-house or purchase externally, judged on cost, capability, capacity, and strategic risk — and the related insource/outsource/offshore/nearshore choices.^[1] From there, strategic sourcing aligns suppliers and contracts to total value: it starts with a spend analysis, then builds a category strategy — treating each group of purchases as a managed business unit. The Kraljic matrix sets the approach by profit impact and supply risk (e.g., partner deeply with a single dominant supplier; compete hard where many suppliers exist).

3.2 Supplier selection, TCO & purchase orders

Suppliers are evaluated on weighted criteria — cost, quality, delivery, capability, financial stability, and risk — using total cost of ownership, not lowest unit price.^[1] Contracts then set price, terms, Incoterms 2020, and service levels (fixed-price shifts cost risk to the supplier; cost-plus shifts it to the buyer). Execution runs through purchase orders — standard, blanket, and contract orders — and the procure-to-pay control of the three-way match (PO, receipt, and invoice must agree before payment).

Domain IV · Internal Operations & Inventory (19%)

The single heaviest domain — 19% of the exam. This is where CSCP overlaps most with CPIM: planning operations (MRP, capacity, distribution), running them lean and around the constraint, and managing inventory. Earn the most points here.

4.1 Planning operations (MRP, DRP, capacity)

Planning cascades from the aggregate plan to the master production schedule (what end items to build and when), then to material requirements planning (MRP) — which explodes the schedule through the bill of materials to time-phase component orders.^[1] MRP II adds capacity, financial, and business planning, while distribution requirements planning (DRP) applies the same time-phased logic to the distribution network. Capacity planning then confirms the plan is executable.

4.2 Lean, JIT & the theory of constraints

Lean maximizes customer value while eliminating the seven (or eight) wastes; Just-in-time (JIT) and Kanban pull production only as needed.^[1] Tools include Takt time (the demand rhythm), Heijunka (leveling), and Poka-yoke (mistake-proofing).

The theory of constraints (TOC) holds that a system’s throughput is limited by its bottleneck, so improving a non-constraint upstream of the bottleneck only piles up work-in-process without raising throughput. Continuous improvement (PDCA, Six Sigma, kaizen) drives it all.

4.3 Inventory management (EOQ, safety stock, ABC)

Inventory decouples operations and buffers variability — at the cost of capital, space, and obsolescence. Order the right amount with the economic order quantity (EOQ — the size that minimizes ordering plus carrying cost), reorder at the reorder point (demand over lead time plus safety stock), and focus control with ABC analysis — a few high-value A items get tight control, many low-value C items get loose control.^[1] Maintain record accuracy with cycle counting and watch the core metrics: inventory turnover and fill rate.

Domain V · Supply Chain Logistics (9%)

9% of the exam — small but high-yield. This domain covers the physical movement and storage of goods: transportation and warehousing, the trade rules that govern cross-border shipments, and the reverse flow of returns.

5.1 Transportation, warehousing & 3PLs

Logistics plans and controls the flow and storage of goods. Choose a transport mode — truck (flexible), rail (low-cost bulk), water (cheapest, slowest), air (fast, costly), pipeline, or intermodal — by the cost/speed trade-off.^[2]

Warehouses receive, store, pick, pack, and ship, and cross-docking flows goods straight from inbound to outbound with minimal storage. Many firms outsource these functions to a third-party logistics (3PL) provider to scale quickly and enter new regions without owning the network.

5.2 Incoterms, trade & reverse logistics

Cross-border shipments run on Incoterms 2020 — the ICC rules that define when delivery occurs and cost and risk transfer between buyer and seller.^[1] They range from EXW (minimum seller obligation) to DDP (maximum).

Under FOB, risk transfers when goods are loaded onto the vessel at the named port of shipment. Add up the landed cost — price plus freight, insurance, duties, and handling — to compare international options fairly.

Finally, the chain runs in reverse too. reverse logistics manages goods flowing back from the customer — returns, recalls, repair, remanufacture, recycling, and disposal — and a closed-loop supply chain is designed to recover that value.

Domain VI · Customer & Supplier Relationships (17%)

One of the three biggest domains — 17% of the exam. A supply chain is a web of relationships. This domain covers managing both ends — customers (CRM) and suppliers (SRM) — to maximize the value each relationship delivers.

6.1 Customer relationship management (CRM)

customer relationship management (CRM) manages the full set of interactions and value across the customer base to win, serve, and retain customers profitably.^[1] It starts by interpreting the voice of the customer, designing service offerings to match, and segmenting customers by customer lifetime value so the highest-value relationships get differentiated service. Performance is measured with KPIs like fill rate, on-time-in-full, and the perfect order, often committed in a service level agreement.

6.2 Supplier relationship management (SRM)

supplier relationship management (SRM) mirrors CRM on the supply side: assess, segment, and develop suppliers to maximize the value each delivers.^[1] Segment suppliers (strategic partners, preferred, transactional) so relationship investment matches each supplier’s value and risk — strategic partners get joint improvement, shared roadmaps, and executive ownership. A supplier scorecard objectively measures quality, delivery, cost, and responsiveness over time, and supplier development builds capability where no qualified alternative exists.

Domains VII–VIII · Risk, Sustainability & Optimization (18%)

The final two domains — Manage Supply Chain Risk (10%) and Evaluate & Optimize the Supply Chain (8%) — together 18%. They zoom out to protecting the chain from disruption and continuously improving it for the long term.

7.1 Supply chain risk management & resilience

supply chain risk management is a structured process: identify risks (supply, demand, process, financial, geopolitical, cyber), assess each by probability and impact, respond, then evaluate.^[1] Combining probability and impact lets you prioritize the most significant exposures.

Mapping the chain often exposes concentration risk — many tier-one suppliers depending on one shared tier-two source. Responses are avoid, accept, mitigate, or transfer — and the goal is supply chain resilience, backed by a business continuity plan.

7.2 Sustainability, the triple bottom line & technology

The final domain optimizes the chain for the long term. Sustainability is evaluated with the triple bottom line — people, planet, and profit — because measuring profit alone can hide social and environmental costs.^[2]

This drives green supply chain management, sustainable sourcing, corporate social responsibility (extended to suppliers), and the circular economy. Optimization also means network redesign and adopting technology — IoT, AI/analytics, blockchain, and automation — to keep improving.
