# Why Engineering Design Drives Logistics Efficiency
Racking may look like steel and bolts, but every decision in its design shows up directly in the efficiency of dozens of daily moments inside the warehouse.
## What does warehouse engineering design mean?
Not just drawing a floor plan. It is a scientific study covering:
- Analysis of goods and labour flow
- Structural load calculations
- Picking path optimisation
- Simulation of peak scenarios
## The effect of design on productivity
MHIA studies from 2024 show that:
- Improving warehouse layout raises worker productivity by 15–35%
- Cutting picking distance by 20% reduces fatigue and raises accuracy
- Placing the highest-demand products in "golden" zones cuts order time by 45%
## The elements of good engineering design
1. **ABC analysis**: classifying products so the highest-demand items are fastest to reach
2. **Slotting optimisation**: fixing the location of each product within the racking system
3. **Flow path design**: mapping optimal routes that minimise crossings
4. **Zone design**: dividing the warehouse into functionally specialised areas
## Return on investment
Across RAFY projects, specialist engineering design delivers:
- Savings of 15–40% on annual labour costs
- Storage capacity up 25–45% within the same footprint
- Payback on the engineering consultancy within 6–18 months
