Goods-to-Person Automation: The Operations Leader’s Guide to Scalable Fulfillment

Efficiency in the warehouse has traditionally been measured by how fast a person can move—how many miles they can log and how many aisles they can navigate. But as labor volatility increases and customer expectations for lightning-fast shipping tighten, the old "person-to-goods" model is hitting a wall.

 

Enter goods-to-person automation—often abbreviated as GTP (and sometimes referred to as G2P). It’s a shift from manual travel to high-speed fulfillment that is fundamentally changing how distribution and fulfillment centers operate.

What Is Goods-to-Person (GTP) Automation?

At its core, GTP is about eliminating the "travel-time waste" problem. In a traditional setup, pickers can spend up to 60%-70% of their shift simply walking. GTP flips the script by using automation, such as high-density storage systems or robotics to bring the exact SKU needed directly to a stationary worker.

Instead of a picker roaming the aisles, the inventory comes to a workstation. It’s the difference between a grocery shopper hunting for items in a store and a chef having the ingredients delivered to their prep table.

The GTP Spectrum: 5 Common Types of Systems

There isn't a one-size-fits-all solution for warehouse automation. The right choice depends on your business’s DNA—your goals, product workflow, facility space and SKU velocity.

• Vertical Lift Modules (VLMs) & Carousels: These automated storage and retrieval systems (AS/RS) move trays and carriers vertically or horizontally on a track to a designated window. They’re excellent for high-value items and utilizing every inch of vertical space.
• Autonomous Mobile Robots (AMRs): These robots automate the retrieval and delivery of inventory to stationary workers. Instead of employees walking through aisles to find items, the AMRs bring shelves, totes or pallets directly to picking stations.
• Pallet Shuttle Systems: High-speed shuttles travel on fixed rails within racking to retrieve specific pallets. This is the go-to for high-volume, high-velocity fulfillment.
• Robotic Picking Arms: By using multi-eye cameras, these arms handle the final pick from a delivered tote, creating a no-touch workflow that reduces repetitive strain for human workers.
• Cube-Based Storage: Think of a dense, vertical grid where bins are stacked to the ceiling. Robots retrieve them from the top, making this the king of space-saving for small parts.

Why Operations Managers are Making the Pivot to GTP

We know the pressure you're under. Solving warehouse labor shortages isn't just about hiring—it’s about protecting and empowering the team you already have. GTP systems provide labor stability by making the job safer and more sustainable.

By bringing the work to the person, you eliminate the physical toll of walking miles a day on concrete floors. This reduction in repetitive strain and fatigue doesn't just lower the risk of injury; it significantly improves worker retention. When you make the warehouse a better place to work, you can scale your capacity without the constant stress of seasonal hiring spikes.

Beyond labor, GTP is a powerhouse for reducing warehouse travel time and improving automated warehouse picking accuracy. When a screen at a workstation tells a picker exactly what to grab, mispicks and costly returns virtually disappear.

Engineering Considerations: Integrating GTP Into Existing Workflows

For the engineering team, the focus is on the mechanics. A successful GTP launch requires seamless Warehouse Management System (WMS) and Warehouse Execution System (WES) integration.

Think of the WMS as the brain that manages inventory and orders, while the WES acts as the central nervous system, orchestrating the real-time movement of the robotics and automated equipment on the floor.

You’ll also need to evaluate physical site requirements like floor load capacity and power distribution. The goal is modular fulfillment—starting with a system that solves today's bottlenecks but can scale as your throughput grows.

Calculating the ROI of Warehouse Automation

Building a business case for the C-suite requires looking beyond just "picks per hour." The ROI of goods-to-person automation includes:

• Space Savings: Reclaiming up to 85% of your floor space for other revenue-generating activities—though most operations see an immediate savings of at least 30%-50%.
• Faster Onboarding: Training time for new hires drops from weeks to hours.
• Lower Error Rates: Drastically reducing the hidden costs of shipping the wrong item—aiming for industry's gold standard 99.9% accuracy rate.
• Improved Employee Recruiting & Retention: In a tight labor market, automation makes roles more attractive—and keeps workers engaged by shifting focus to higher-value tasks, consistent workflows and skill development.

Is GTP Right for Your Operations?

GTP is a game-changer for operations with high SKU counts, small item sizes and high order volumes. However, the best system is the one that fits your specific flow. Whether you're looking for the flexibility of AMRs or the density of a VLM, the transition to automation is about making your operation more resilient.

RSC Automation Expert Insight "GTP system is right for your operation if your pickers spend more than 50% of their time walking, your facility handles over 1,000 orders daily, or you're severely constrained by physical warehouse space.  When applied correctly, you can reapply up to 60% of your workforce toward higher-value, strategic roles." Vic Cotto, Systems Engineer

Taking the First Step: How to Start Your GTP Journey

Moving toward automation doesn't have to be an all-or-nothing investment. Most successful implementations start with a focused pilot program in a single high-velocity zone. Here's how to begin:

1. Audit Your Travel-Time Waste: Calculate exactly how many miles your pickers walk per shift. This is your primary baseline for justifying the switch.
2. Define Your Top KPI: Are you solving for floor space, labor scarcity or order accuracy? Identifying your primary bottleneck will dictate whether you need the density of an AS/RS or the flexibility of AMRs.
3. Consult with an System Integration Partner: Take your data and make it a reality. Working with an Engineered Solutions team like the one here at Raymond Storage Concepts ensures that from the initial assessment and recommendation through the final installation, your automation strategy is built for long-term performance. 

Transitioning to GTP is about future-proofing your operation—so that when the next peak season hits, your warehouse is ready to scale without the stress. Reach out to RSC Engineered Solutions to start your GTP journey.

FAQs

How does goods-to-person differ from person-to-goods?

In person-to-goods, pickers walk to the items. In GTP, robotics or conveyors deliver items to the picker. This eliminates the 60%-70% of shift time typically wasted on walking.

What is the typical ROI for a GTP system?

Most operations see a full return within 12-24 months. This accounts for labor savings, reclaimed floor space and reduced error rates. However, many companies are willing to extend to 36 months or more to realize strategic benefits including throughput capacity for future growth and avoiding future facility expansion costs.

Can GTP automation integrate with my current WMS?

Yes. Modern GTP solutions use APIs to communicate with your existing Warehouse Management System for real-time inventory and order orchestration.

Do I need a "lights-out" warehouse to use GTP?

No. A "lights-out" warehouse refers to a fully automated facility that requires zero human presence—often literally operating in the dark. GTP is designed to work alongside your team, improving their ergonomics and productivity rather than replacing the human element entirely.

What is the maintenance requirement for warehouse robotics and automated equipment?

It varies. AMRs require basic sensor and battery care, while fixed AS/RS systems need scheduled mechanical inspections. Many integrators offer Lifecycle Services that includes maintenance plans, parts programs, technical support, retrofitting and more.
