- Warehouse Flow Optimization
Implementation Engineers improves warehouse flow by optimizing how materials and products are received, stored, replenished, picked, staged, and moved through warehouse and distribution operations through warehouse flow optimization.
We evaluate the complete flow of materials, people, information, and transactions to identify congestion, unnecessary movement, poor space utilization, inventory inaccuracies, inefficient picking, replenishment gaps, and process breakdowns that limit throughput and service as part of material flow improvement.
IE then implements the warehouse processes, layouts, inventory strategies, standard work, systems, visual controls, KPIs, and daily management routines required to improve flow and sustain performance—before assuming additional automation, technology, or warehouse space is required through warehouse process improvement.
What We Implement
Warehouse Flow & Process Design
Create a simpler, more efficient flow of materials through the warehouse.
IE evaluates receiving, put-away, storage, replenishment, picking, staging, and shipping processes to identify unnecessary movement, handling, waiting, and process complexity.
We redesign workflows around demand, material characteristics, operating requirements, and physical constraints to improve throughput and reduce travel and handling.
Layout, Storage & Space Optimization
Increase usable warehouse capacity within the existing footprint.
IE evaluates rack utilization, storage locations, aisle configuration, material placement, containers, pallets, staging areas, and other physical constraints as part of warehouse layout optimization and warehouse space optimization.
We consolidate unnecessary locations, standardize storage, remove obsolete materials from prime locations, and restructure the warehouse to make better use of available space through warehouse capacity optimization.
Slotting & Inventory Segmentation
Position inventory based on how it actually moves.
IE segments inventory based on factors such as demand frequency, velocity, size, value, operational requirements, and obsolescence through warehouse slotting optimization.
Fast-moving materials can be positioned closer to high-frequency pick paths while slow-moving and obsolete materials are managed differently, reducing unnecessary travel and improving picking efficiency.
Picking & Order Fulfillment
Improve picking productivity, accuracy, and order turnaround.
IE analyzes pick paths, order profiles, picking methods, item locations, routing logic, and labor requirements to identify opportunities to increase productivity as part of picking productivity.
We implement improved picking strategies, standard work, order segmentation, routing, and performance measures to reduce travel and increase lines picked per labor hour.
Inventory Accuracy & Cycle Counting
Make sure system inventory matches what is physically in the warehouse.
IE establishes cycle-counting processes, bin audits, reconciliation standards, inventory classifications, transaction controls, and accountability to improve inventory accuracy through warehouse cycle counting and inventory accuracy.
Better inventory accuracy reduces time spent searching for materials and improves replenishment, planning, picking, and customer service.
Replenishment & Material Availability
Keep pick locations supplied without creating unnecessary inventory.
IE improves warehouse replenishment processes and parameters to ensure materials are available where and when they are required.
We connect inventory policies, replenishment parameters, demand, material movement, and warehouse execution to reduce shortages and unnecessary handling.
Warehouse Management Systems & Technology
Use technology where it creates value—not as a substitute for good processes.
IE evaluates existing ERP and WMS functionality, scanning, barcoding, warehouse data, and other technologies against operational requirements.
Where technology investment is warranted, we help ensure the processes, data, workflows, and operating model are ready to support it. Where it isn’t, significant performance improvements may be achievable by first fixing the underlying warehouse processes.
Warehouse Performance Management
Create daily visibility and accountability around execution.
IE implements warehouse KPIs, visual management, tiered meetings, standard work, and daily management routines around measures such as picking productivity, shipment accuracy, inventory accuracy, replenishment accuracy, throughput, and labor productivity.
Why Warehouse Flow Matters
More Space and More Technology Aren’t Always the Answer
When a warehouse reaches its limits, the immediate response is often to add space, labor, automation, or technology.
But the constraint may actually be the way the existing warehouse operates.
Inventory stored across multiple locations increases travel and complexity. Fast-moving products may occupy inefficient locations while obsolete inventory consumes valuable space. Poor inventory accuracy forces employees to search for materials. Inefficient pick paths reduce productivity. Inconsistent replenishment creates shortages at the point of use.
Adding technology to these processes can simply automate existing inefficiency.
Effective warehouse flow starts by understanding how materials should move through the operation and designing the physical layout, storage strategy, inventory policies, processes, systems, and daily routines around that flow.
IE focuses first on creating a warehouse that is organized, visible, accurate, and executable. Technology and automation can then be applied where they provide additional value.
The objective is not simply a cleaner warehouse. It is greater throughput, capacity, inventory accuracy, productivity, and service from the operation.
IX® in Action | Electrical Components Manufacturing
Unlocking Warehouse Capacity Without Automation or New Technology
A leading electrical components manufacturer operated a foundry and adjacent warehouse supporting both external customers and downstream manufacturing operations.
As demand increased, the warehouse became a bottleneck, putting production support and on-time delivery at risk. The company needed the operation to support a planned $30 million increase in sales throughput without major capital investment or new warehouse technology.
The warehouse faced several fundamental execution problems. Inventory was difficult to locate despite appearing available in the system, storage was cluttered and inconsistent, SKUs were spread across multiple locations, picking averaged only 7.5 lines per hour, and fast-, slow-, and obsolete-moving inventory were being managed similarly.
Implementation Engineers redesigned the warehouse around four principles: Create Clean. Create Space. Create Order. Create Speed.
What We Implemented
- 5S & Visual Management: Implemented 5S across the warehouse, standardized storage, established visual controls, and introduced bin audits.
- Storage Consolidation: Consolidated SKUs across pick locations and reduced item/location combinations by 30%.
- Space Optimization: Increased empty storage locations from approximately 60 to more than 150 and separated excess and obsolete inventory from active storage.
- Inventory Segmentation: Developed an A–E inventory classification incorporating operational and financial data.
- Slotting: Repositioned high-volume items to create more logical pick paths and reduce travel.
- Inventory Accuracy: Implemented SAP cycle counting, reconciliation standards, bin audits, and corrections to master data and replenishment parameters.
- Picking Optimization: Improved pick-list format and routing logic and implemented a segmented process for high-frequency, small orders.
- Performance Management: Established KPIs for lines per hour, COGS shipped per labor hour, shipment accuracy, and replenishment accuracy, supported by visual boards and daily reviews.
Results:
95%+
inventory accuracy in the core warehouse area, up from approximately 50%
172%
increase in storage capacity within the existing footprint
33%
increase in picking productivity, from 7.5 to 10+ lines per hour
The implementation also delivered a 30% reduction in item/location combinations, 17% reduction in warehouse complexity, improved shipment accuracy, faster order picking, and more reliable support for downstream operations.
Most importantly, the warehouse moved from being a constraint to supporting growth without automation, scanners, new technology, or additional warehouse space.
Frequently Asked Questions
What is warehouse flow optimization?
Warehouse flow optimization is the process of improving how materials and products are received, stored, replenished, picked, staged, and moved to increase throughput, capacity, accuracy, and productivity within the existing warehouse.
How can warehouse capacity be improved without adding more space?
By consolidating storage locations, removing obsolete inventory from prime space, optimizing layout and slotting, standardizing storage, and restructuring the physical flow to make better use of the existing footprint.
What is warehouse slotting and why is it important?
Warehouse slotting positions inventory based on demand velocity and characteristics so fast-moving items are closer to high-frequency pick paths, reducing travel time and improving picking efficiency.
How can cycle counting improve warehouse inventory accuracy?
Cycle counting establishes regular, controlled counts, reconciliation standards, and accountability so system inventory matches physical inventory, reducing search time and improving replenishment and service.
How can picking productivity and order accuracy be improved?
By optimizing pick paths, slotting high-velocity items, improving order routing and segmentation, implementing standard work, and measuring lines picked per labor hour and shipment accuracy.
When should a business invest in a warehouse management system?
After core processes, layout, slotting, inventory accuracy, and daily management routines are stable. Technology should support good processes rather than automate existing inefficiency.
