Network Strategy — How to optimise your physical footprint across manufacturing, warehousing, and distribution
Every pallet that moves through your business carries an implicit tax: the cost of location. That tax is paid in transport margins, inventory carrying, lost sales through stockouts, capital tied to facilities, and the day-to-day friction of running sites that are too many, too far apart, or simply the wrong shape.
Designing the right network — where to place factories, distribution centres (DCs), and cross-dock hubs; how many to keep; and which sites to consolidate or expand — is one of the most powerful levers a supply-chain leader has. Done right, a network reduces total landed cost, improves customer service, and builds resilience. Done poorly, it leaves the business paying for inefficiency for years.
This guide is for supply-chain leaders, logistics managers, CFOs and executives across Australia and New Zealand. It explains the core principles of network strategy, the practical trade-offs you will face, the models and analytics you need, and a pragmatic, implementable roadmap. It finishes with a clear list of ways Trace Consultants can help — from rapid diagnostics to full end-to-end design and implementation.
Why network strategy matters now
A few currents make robust network strategy essential for ANZ organisations today:
- Geography and population concentration. Australia’s population is heavily concentrated on the east coast with long inter-city distances and expensive road and rail legs. New Zealand’s geography is compact but constrained by strait crossings and regional logistics costs. Both markets demand careful placement of capacity to balance service and cost.
- Rising transport costs and volatility. Fuel price swings, driver shortages and freight rate volatility make transport a major and variable cost.
- Customer expectations. Faster delivery windows, omnichannel fulfilment and same/next-day expectations press networks to be closer to customers.
- Inventory and working capital pressure. Warehouses are expensive real estate — and holding too much inventory across many sites ties up cash.
- Resilience and risk. Natural disasters, port congestion and supplier disruptions require networks that can absorb shocks without total collapse.
- Sustainability goals. Shorter transport distances, fewer touch points and consolidation reduce emissions and support corporate sustainability targets.
Network strategy is the intersection of operations, finance and commercial strategy — and it requires rigorous analysis paired with practical implementation plans.
The core principles of network design
Network design is a disciplined exercise in trade-offs. There are no free lunches; every decision trades cost for service, capital for flexibility, or proximity for scale. Core principles include:
- Define the service promise first. Service targets (delivery time windows, fill rates, returns handling) dictate the geometry of the network. Without clearly defined service levels by customer segment, optimisation is meaningless.
- Optimise for total landed cost, not headline metrics. Compare scenarios on a total cost basis that includes transport, inventory carrying, facility cost, handling cost, lost sales and risk premium — not only per-unit warehouse cost.
- Use activity-based modelling. Map activities (receiving, cross-dock, replenishment, picking) to time and cost. This enables realistic labour and equipment assumptions.
- Include lead times and variability. Model the effect of variability in supplier lead times, demand spikes and transport TATs — not just mean lead time.
- Respect geography and infrastructure realities. Road conditions, port capacity, rail availability and regional labour markets must shape feasible solutions.
- Consider the whole lifecycle. Include migration costs, lease terms and capital spend. A new DC may be operationally better but financially unviable if lease breakup and mobilisation costs are ignored.
- Plan for resilience. Design for alternate fulfilment routes, dual supply and contingency capacity, particularly for critical SKUs.
- Link to commercial strategy. If you pursue premium, fast fulfilment in certain segments, design nodes closer to those customers or adopt micro-fulfilment. If cost leadership is the goal, cluster capacity to exploit scale.
Common network archetypes and when they make sense
There are several dominant patterns for network design. Your choice depends on customer promise, product characteristics and cost structure.
- Centralised / hub-and-spoke: A few large facilities supply regional spokes. Advantages: scale economies, lower inventory overall, simpler management. Suitable for commodity products with long lead times and where transport costs are relatively low vs facility costs. Risk: single-point failures and longer lead times to remote customers.
- Decentralised / regional network: Many regional warehouses closer to customers improve service and reduce last-mile costs. Advantages: faster delivery and lower last-mile cost. Suitable for perishable, high-service or bulky products. Risk: higher fixed costs and inventory duplication.
- Hybrid network: A centralised DC for bulk replenishment with regional cross-dock or mini-hubs for quick fulfilment. This is commonly used where a blend of service and cost is required.
- Direct-to-store or direct-to-customer models: Manufacturers ship directly to stores or customers, reducing distribution layers. Works well for high-value, low-SKU lines and when inventory visibility is strong.
- Micro-fulfilment / urbanisation: Small, automated fulfilment centres in or near large cities to enable same-day delivery with lower transport costs. Best for fast-moving consumer goods in dense metro areas.
- Third-party logistics (3PL) / multitenant DCs: Useful to scale quickly without capital, and to test new regions. Considerations include control, data visibility and cost.
Selecting an archetype is a strategic choice; many modern networks are hybrids that blend two or three patterns.
The analytics and models you need
A robust network strategy relies on analytics that are both rigorous and practical. Core modelling tools include:
1. Demand & order flow mapping
Understand where demand originates, order frequency, order sizes, SKU velocity and geographic heatmaps. For omni-channel, map both fulfilment and returns flows.
2. Transportation modelling
Model transport cost and lead time across lanes, including modal options (road, rail, coastal shipping), backhaul optimisation, and last-mile carrier options. Include seasonality and surge scenarios.
3. Inventory modelling
Use stochastic inventory models to determine safety stock, reorder points and cycle stock at facility level. Inventory trade-offs change rapidly with number of nodes.
4. Facility and handling cost modelling
Activity-based costing for labour, equipment, racking and utilities. Differentiate cost by facility typology (automated, bulk, pick-and-pack).
5. Network optimisation engines
Use mathematical optimisation to test thousands of location and allocation scenarios. Common techniques include mixed-integer programming and location-allocation models.
6. Scenario & sensitivity analysis
Stress-test candidate networks against demand shifts, supplier outages, energy price shocks and labour strikes. Understand where cost and service are brittle.
7. Total cost of ownership (TCO) & financial modelling
Translate operational scenarios into cashflow models: CapEx, lease costs, operating costs, staffing, tax impacts and working capital changes. Include transition costs: mobilisation, recruitment, and consultancy costs.
8. Sustainability & emissions modelling
Estimate transport and facility emissions to understand environmental trade-offs. Shorter networks often reduce emissions; centralisation can increase efficiency but lengthen transport legs.
These analytics are the inputs to a defensible decision — not the decision themselves. The qualitative assessment (labour availability, planning competence, local zoning) matters too.
Practical trade-offs you will face
Optimising the network forces hard calls. Here are the trade-offs you’ll repeatedly confront:
- Proximity versus scale: Adding regional sites reduces last-mile cost and time, but increases fixed costs and inventory duplication.
- Inventory vs transport: More nodes typically require more inventory but can lower transport cost. Decide which cost pool you are willing to trade.
- Capital vs operating cost: Automated, large DCs lower per-unit operating cost but require significant capital and longer payback.
- Lease flexibility vs optimal location: Prime locations that deliver service often come with lengthy lease commitments or high real-estate cost.
- Resilience vs efficiency: A lean, centralised network is efficient but fragile. Redundancy costs money but may be necessary for critical SKUs.
- Outsourcing vs control: 3PLs reduce capital expenditure and speed market entry, but limit control and data transparency.
- Sustainability vs speed: Shorter distances lower emissions, but smaller regional sites may reduce efficiency per square metre. Balance is needed.
Explicitly quantify these trade-offs in the model and then overlay qualitative filters — such as strategic supplier locations or regulatory constraints.
Step-by-step network optimisation approach
Below is a practical process you can follow. You don’t need every fancy tool to start — but you do need data discipline and governance.
Step 1 — Set objectives and constraints
Define financial KPIs (total landed cost, inventory days, service levels), strategic constraints (regional presence, local content), and non-negotiables (safety stock for critical SKUs).
Step 2 — Build a single source of truth
Consolidate demand history, SKU master, site attributes, transport lanes, costs, and lead-times into a single dataset. Incomplete or inconsistent data is the most common failure mode.
Step 3 — Segment product and customer portfolios
Not all SKUs should be treated the same. Segment by demand volatility, density, value and service requirement. This permits differentiated architecture (e.g. regional hubs for fast-moving lines, centralised bulk for slow movers).
Step 4 — Map current flows and costs
Visualise current flows and compute baseline TCO. This becomes your comparator for all scenarios.
Step 5 — Generate candidate networks
Use optimisation tools or heuristics to propose candidate networks: fewer large hubs, a hybrid model, regional clusters, micro-fulfilment overlay. For each, set allocation rules (which SKUs go where).
Step 6 — Evaluate scenarios
For each candidate, compute service metrics, transportation cost, handling cost, inventory requirement, emissions, and financial outcomes. Include transition costs and lease implications.
Step 7 — Conduct sensitivity tests
Stress test scenarios against demand shifts, supplier failure, fuel price spikes and labour shortages. Select options that perform acceptably across plausible futures.
Step 8 — Build an implementation roadmap
Choose a preferred scenario and translate it into a phased execution plan. Consider pilot sites, lease renewals, CapEx schedule, staffing, and systems integrations.
Step 9 — Manage transition risks
Set governance for cutover, data migration, training and supplier communication. Use readiness gates before committing to full migration.
Step 10 — Measure and iterate
After go-live, track performance against KPIs and adjust. Network design is not a once-off — customer patterns and costs evolve.
Practical considerations for Australia & New Zealand
A few practical notes specific to ANZ:
- East-coast density in Australia. Most population and economic activity is clustered in Brisbane–Gold Coast, Sydney, Canberra, Melbourne and Adelaide. East-coast hubs often make sense for national coverage, but coastal shipping and rail should be evaluated for bulk movements.
- Long inter-city distances in Australia. Freight lanes across states are lengthy; modal choice (road vs rail) and cross-dock timing become major cost drivers.
- Regional towns and last-mile costs: Remote and regional deliveries can be expensive. Consider store fulfilment, local hubs, or carrier networks specialised in regional delivery.
- New Zealand island logistics: The North and South Island dynamics, ferry capacity and port constraints can create bottlenecks — plan node locations with inter-island continuity in mind.
- Seasonality & retail peaks: Australian retail peaks (Christmas, EOFY, summer) and ANZ agricultural seasonality must be modelled.
- Labour markets: Regional labour availability varies widely. Automation may be the only way to staff certain locations, or you may need to favour urban hubs.
- Coastal shipping and intermodal: Both countries have cost-competitive coastal and rail options for certain flows — include these in your transport modelling.
Local knowledge matters; a model that ignores these realities will recommend infeasible sites.
Implementation pitfalls and how to avoid them
Even the best design can fail in execution. Common pitfalls:
- Underestimating transition cost and complexity. Mobilising a new site, migrating systems and retraining staff are time-consuming and costly.
- Poor lease and property timing. Never assume you can secure a site on your preferred timetable. Align network change with lease expiries where possible.
- Ignoring people and unions. Workforce implications can cause industrial and reputational issues — plan communications and transition support.
- Over-reliance on theoretical productivity gains. Validate productivity assumptions with on-site time studies or pilots.
- Neglecting IT and integrations. Failures to integrate order allocation, WMS and TMS undermine expected benefits.
- Insufficient contingency planning. Have contingency capacity and alternate suppliers/kits for critical SKUs.
Mitigate these by building realistic plans, running pilots, and including change costs in your TCO.
KPIs and governance for a living network
A good network needs active management. Track these KPIs:
- Total landed cost per unit (transport + handling + inventory + facility cost).
- Inventory days / stock turns by node and across the network.
- On-time in full (OTIF) to customers and SLA attainment.
- Transport cost per order and per kilometre.
- Warehouse productivity metrics (lines picked per hour, cost per pick).
- Site utilisation (storage fill %, throughput vs capacity).
- Carbon intensity / emissions per order where sustainability matters.
- Customer satisfaction & lost sales attributable to network performance.
Governance: a cross-functional Network Steering Committee should meet monthly during transition and quarterly in steady state to review KPIs, approve changes and plan capital investments.

A practical 12-month roadmap to start optimising your network
- Month 0–1: Sponsor alignment, define KPIs and governance.
- Month 1–3: Data consolidation — SKU, demand, cost, lane and site attributes. Build single source of truth.
- Month 3–4: Quick wins & tactical changes — lane rationalisation, carrier renegotiation, re-allocation of SKUs to existing sites.
- Month 4–6: Scenario generation using optimisation tools; product/customer segmentation and candidate network shortlists.
- Month 6–8: Financial modelling, sensitivity analysis and selection of preferred scenario. Prepare business case.
- Month 8–9: Property and lease feasibility, site testing, and pilot planning.
- Month 9–12: Pilot implementation (pilot DC or pilot process), validate productivity and refine assumptions.
- Month 12+: Scale rollout, systems integration, workforce onboarding and continuous monitoring.
Adapt timing to your organisation — larger, more complex businesses will need longer pilots and staged rollouts.
Network strategy sits at the heart of the supply chain. It converts operational choices into financial outcomes and determines your ability to serve customers consistently, cheaply and sustainably. The best networks are not static blueprints but living architectures — refreshed as demand patterns, transport economics and commercial strategies change.
Start by defining your service promise, get your data in order, segment product flows, model total landed cost and stress-test the network against realistic shocks. Treat the change as a programme — with governance, pilots and a clear link to finance.
If you’d like pragmatic, ANZ-focused support — from a rapid network diagnostic to a full optimisation and implementation programme — Trace Consultants can help. We combine modelling rigour with implementation experience so your network design becomes an executable advantage, not a theoretical exercise.
