SC Drivers - Overview

Note

Definition: Levers a supply chain uses to balance responsiveness vs. efficiency, and maximise overall SC profit.

There are 6 SC Drivers, grouped into two categories:

• Logistical Drivers - physical entities: Facilities, Inventory, Transportation
• Cross-sectional Drivers - enable and coordinate the physical drivers: Information, Sourcing, Pricing

The six drivers are the levers that balance responsiveness against efficiency; their combined effect determines the responsiveness and profitability of the entire supply chain.

Driver 1 - Facilities

Logistical Driver

Facilities include plants, warehouses, and retail stores - any physical place where inventory is stored or converted. Their role is to receive, store, or convert raw materials, WIP, or finished goods at each node of the supply chain.

There are four facility decision dimensions, each with a Responsive and an Efficient option:

(a) Capacity

Decision	SC Impact
Large capacity	Handles higher volumes, fewer resources needed, lower unit cost → Efficient SC
Small capacity	Adaptable to demand and market changes, higher unit cost → Responsive SC

(b) Location

Decision	SC Impact
Centralised	Economies of scale → Efficient SC
Decentralised (closer to customers)	Faster availability → Responsive SC

(c) Production Facility Type

Decision	SC Impact
Flexible (multi-product, shared equipment and workers)	Higher variety → Responsive SC
Dedicated (fixed machines and manpower, limited variety)	Large quantity, low variety → Efficient SC

(d) Warehouse Type

Decision	SC Impact
Cross-docking	Inventory moves without long storage; mix-and-match per customer need → Responsive SC
Dedicated storage	Large volumes, minimal cost → Efficient SC

Capacity

• Large → higher volumes, lower unit cost · Efficient
• Small → adaptable to demand, higher unit cost · Responsive

Role

• Production: Flexible · Responsive / Dedicated · Efficient
• Warehouse: Cross-docking · Responsive / Storage · Efficient

Location

• Centralised → economies of scale · Efficient
• Decentralised → closer to customers · Responsive

Facilities driver - every facility decision (capacity, role, location) trades off between an efficient and a responsive supply chain.

Driver 2 - Inventory

Logistical Driver

Note

Primary role of inventory: Bridge the gap between supply and demand.

3 Components of Inventory

Component	Description
Cycle Inventory	The same quantity ordered repeatedly in a cyclic pattern
Safety Inventory	Minimum buffer stock maintained to prevent stockouts or process disruption
Seasonal Inventory	Extra stock carried during peak or seasonal demand periods

The Inventory Trade-off

Inventory Level	Outcome
High inventory	Fulfils demand fully → Responsive SC - but adds holding cost
Low inventory	Lowers holding cost → Efficient SC - but risks poor service levels and lost customers (severe business penalty)

Inventory Location Strategy

SC Type	Strategy
Responsive	Carry high finished goods inventory; place it closer to consumers for faster availability
Efficient	Carry finished goods at a centralised location → enables order consolidation and transportation optimisation → lower cost

Tip

Application of Concepts: A supply chain can be a mix of responsive and efficient - it does not have to be a pure strategy. For example, a company may hold centralised safety stock (efficient) while keeping a small responsive buffer near key urban markets.

Cycle inventorySafety inventorySeasonal inventory

High availability → Responsive

• Large finished-goods stock, held close to consumers
• High responsiveness - but high holding cost

Low availability → Efficient

• Centralised inventory, order consolidation
• Lower cost - but risks stockouts & lost customers

Inventory driver - three components (cycle, safety, seasonal) and one core trade-off: find the right location and quantity for an optimal level of responsiveness at the lowest cost.

Driver 3 - Transportation

Logistical Driver

Transportation moves raw materials from supplier to manufacturer, and finished goods from manufacturer to the final customer. Two key decisions govern transportation strategy:

(a) Network Design

Design	Description
Direct shipping	Manufacturer ships straight to the demand point with no intermediary
Through intermediaries	Routed via distributors or hubs depending on whether the SC needs to be responsive or efficient

(b) Mode of Transport

Mode	Speed	Cost	SC Type	Best For
Air	Fast	High	Responsive	High-value, low-demand products
Sea	Slow	Low	Efficient	Low-value, high-demand products
Rail / Road	Intermediate	Intermediate	Mixed	Balance of cost and speed

Transport Strategy Summary

SC Type	Approach
Responsive	Rapid transport modes (Air); centralised facility stores wide variety; direct delivery to consumer
Efficient	Low-cost transport modes (Sea/Rail); bring inventory closer to customers to minimise last-mile cost

High value & low demand → Responsive

• Rapid transport (Air)
• Centralised facility → direct delivery to consumer

Low value & high demand → Efficient

• Low-cost transport (Sea / Rail)
• Inventory kept close to the customer

Network: direct to demand pointNetwork: through intermediaryAirTruckRailSea

Transportation driver - two decisions (network design and mode of transport) set the balance between rapid, responsive delivery and low-cost, efficient movement.

Driver 4 - Information

Cross-Sectional Driver

Note

Information is the master driver - it enables and coordinates all five other drivers. It is critical for both push and pull production systems.

Push vs. Pull Systems

System	How it works	Role of Information
Push	Production based on forecast and historical demand; products made or services planned in advance of actual orders	Used for advance planning and scheduling
Pull	Production triggered by actual customer demand or order	Enables quick response and real-time partner collaboration

Other Roles of Information

• SC coordination: Every SC phase collaborates to maximise overall SC profitability through information sharing across partners.
• Cross-functional alignment: Sales, marketing, and production are all aligned to business requirements via shared information systems.

Information Strategy by SC Type

SC Type	Information Applications
Efficient SC	Forecasting, inventory management, supplier collaboration, production planning, transport optimisation
Responsive SC	Real-time visibility (ML methods), demand sensing, demand shaping via promotions, scenario planning - all aimed at reducing response time

---

Driver 5 - Sourcing

Cross-Sectional Driver

3 Components of Sourcing Decisions

Component	Description
Procurement	Decisions on the types of materials required (covered in detail via the Kraljic Matrix in future sessions)
Sourcing strategy	Single vs. multiple sourcing | In-house production vs. outsourcing
Supplier selection	Identify requirements → find and qualify suppliers who can fulfil them

Sourcing Strategy by SC Type

SC Type	Sourcing Approach
Efficient SC	Cost optimisation + economies of scale + supplier consolidation
Responsive SC	Supplier collaboration to handle disruptions quickly + maintain a base of alternative suppliers so no demand goes unfulfilled + customisation strategies

Tip

Application of Concepts: The Kraljic Matrix - referenced here for future sessions - classifies purchased items by supply risk and profit impact. It is a foundational tool for deciding whether to single-source, multi-source, or build strategic supplier partnerships, directly linking procurement decisions to SC responsiveness or efficiency.

Driver 6 - Pricing

Cross-Sectional Driver

Note

Key principle: Customers who want responsiveness and customers who want efficiency are entirely different market segments. The right pricing strategy must target the right segment.

Pricing Strategy	How It Works	SC Type
Economies of Scale Pricing	Suitable for large batch production; cost-effective, reduces changeover cost	Efficient SC
EDLP (Everyday Low Pricing)	Price stays steady over time; predictable demand signal	Efficient SC
Fixed Pricing	Set, unchanging prices	Efficient SC
High-Low Pricing	Different prices at different times through discounts and promotions; creates dynamic demand	Responsive SC
Menu Pricing	Price varies by response time, delivery location, or product attributes	Responsive SC

Economies of scalebig-batch, saves changeover cost

EDLP vs High-Lowsteady price vs weekly discounts

Fixed vs Menu pricingvaries by response time / location

→

Pricing

Customers who prefer responsiveness

• High-low pricing · menu pricing

Customers who prefer efficiency (cost)

• EDLP · fixed pricing · economies-of-scale pricing

Pricing driver - pricing targets two divergent segments: customers who value responsiveness and customers who value low cost.

Tip

Exam Angle: “Explain the role of SC drivers in making a supply chain responsive or efficient.”

Answer framework:

1. Define Responsive SC (speed, fulfil customer need fast) vs. Efficient SC (minimise cost)
2. Name all 6 drivers with their two categories (Logistical + Cross-sectional)
3. Walk through the table above - for each driver, state the responsive and efficient option with one example
