Why Material Flow is Just as Important as Production Speed

Manufacturers often focus on maximizing production speed—how quickly machines can assemble parts, how fast workers can complete tasks, and how much output can be achieved in a given timeframe. While production speed is crucial, it’s only one piece of the efficiency puzzle. What often gets overlooked is material flow—the movement of raw materials, components, and finished products throughout the factory.

Even the fastest production lines can be slowed down or completely halted by inefficient material flow. If the right parts aren’t in the right place at the right time, production speed becomes meaningless. In this post, we’ll explore why material flow is just as important as production speed and how manufacturers can optimize it to maximize efficiency.

What is Material Flow?

Material flow refers to the movement of materials throughout the manufacturing process, from receiving raw materials to storing, staging, picking, assembling, and shipping finished goods. A well-optimized material flow ensures that components arrive at production lines exactly when needed, minimizing delays and maximizing efficiency.

Common material flow issues include:

• Parts not arriving at production lines on time.
• Excessive material movement leading to wasted labor.
• Storage locations being too far from production areas.
• Frequent stockouts or overstocked inventory causing production bottlenecks.

When material flow is inefficient, production teams end up waiting for parts, searching for misplaced inventory, or dealing with constant interruptions—all of which slow down operations, no matter how fast production lines are capable of running.

How Poor Material Flow Cancels Out Fast Production

Production Bottlenecks Due to Inventory Delays

A common misconception is that production lines stop only when machines fail or workers fall behind. In reality, poor material flow is one of the biggest contributors to downtime.

If parts aren’t available when needed, operators must wait while someone retrieves them, leading to unnecessary delays. Worse, if stock records are inaccurate, the wrong parts might be pulled, requiring time-consuming corrections.

Solution: Implement real-time inventory tracking to ensure production always has the right materials available. Integrate smart storage solutions that provide instant access to part locations and usage history.

Unnecessary Material Handling Wastes Time

Every time a part is moved unnecessarily, it adds wasted time to the production process. Walking across a large factory floor to retrieve components, manually scanning and logging inventory, or repacking materials multiple times before they reach the line are all examples of non-value-added activities.

Solution: Optimize storage locations by placing high-usage components close to production lines. Use smart storage solutions to reduce time spent locating, picking, validating, and tracking parts.

Overloaded Work Areas Create Chaos

Poor material flow can lead to excess materials accumulating in production areas, causing clutter and inefficiencies. When too many parts are staged at once, operators waste time navigating around unnecessary materials, increasing the risk of mispicks and errors.

Solution: Smart storage systems can ensure that only the necessary materials are delivered at the exact moment they are needed, eliminating work area congestion. Storing more material at the production lines can also reduce the need to pick and stage parts head of time in the first place.

Stockouts and Overstocking Lead to Inefficiency

When material flow isn’t optimized, manufacturers often struggle with either too much inventory or not enough. Stockouts can bring production to a halt, while excess inventory takes up valuable space, increasing time spent picking parts and carrying costs.

Solution: Implement demand-driven material flow, using real-time data from smart storage and ERP/MRP systems to maintain the right inventory levels. Smart storage systems that integrate with supply chain partners can further automate inventory management processes as well.

Optimizing Material Flow for Maximum Efficiency

Integrate Smart Storage and Automated Picking Systems

Smart storage systems minimize time spent locating and picking parts. Integration with ERP/MRP/MES systems also reduce the need to verify parts and can eliminate manual transactions in other systems.

Use Data to Predict and Optimize Material Movement

Analyze historical inventory usage to predict demand and avoid stockouts. Track material flow patterns and measure your processes to identify bottlenecks and determine areas where you can make improvements.

Align Storage Locations with Production Needs

Store as much material as possible near your production lines, especially focusing on your highest-usage components. Parts stored on the production lines can be picked directly from storage into the production machines without the need for kitting processes. 

Implement Smarter Material Processes

Use data from smart storage to automatically replenish materials based on real-time inventory levels. Automatically call for more material on the production line from secondary stock locations, or even automatically re-order critical parts from supply-chain partners. Pick materials only when they are needed, ensuring your parts stay in verified smart storage locations as much as possible.

Final Thoughts

Fast production lines are useless if materials aren’t flowing efficiently. Poor material flow leads to stockouts, excessive handling, and wasted labor—all of which reduce productivity and increase costs. By optimizing material flow with smart storage, real-time tracking, and automation, manufacturers can ensure that materials arrive exactly when and where they are needed.

Improving material flow isn’t just about speed—it’s about creating a seamless, efficient operation that maximizes throughput while minimizing waste. Investing in better material flow solutions today will pay off in higher efficiency, lower costs, and more reliable production tomorrow.
