Amazon’s Project Tetromino Points to the Next Frontier in Last-Mile Automation

Published

on

Amazon has spent years automating fulfillment centers, where robots move inventory, assist picking, sort products, and reduce the number of touches required to get an order out the door. Its next major automation challenge may be much closer to the customer.

Amazon is reportedly developing an advanced delivery-station concept known internally as Project Tetromino, designed to automate more of the work that occurs immediately before packages are loaded into delivery vehicles. According to reporting by Business Insider, an internal planning document suggested the concept could process packages at roughly 2.5 times the rate of Amazon’s existing delivery-station design.

The precise rollout plan is far from settled. Amazon told Business Insider that Tetromino remains an early-stage concept and that specific investment figures and timelines contained in the document no longer reflect the company’s current plans. But whether those particular numbers survive is almost beside the point.

The more important story is where Amazon is trying to automate next.

Moving Automation Downstream

Delivery stations occupy a particularly difficult position within parcel networks. They receive packages after fulfillment and middle-mile transportation, sort them into individual delivery routes, sequence and stage those shipments, and prepare them for delivery drivers.

Amazon says its European delivery stations can involve roughly 40 different operational processes as packages move from arrival to final dispatch. The company has committed more than €700 million to delivery-station technology in Europe, including systems for unloading, sorting, scanning, and reducing repetitive manual handling. Amazon has detailed that investment and its delivery-station automation strategy here.

Historically, many of these processes have required considerable manual handling because a delivery station deals with a constantly changing mixture of parcel sizes, destinations, routes, vehicles, and departure times.

That variability makes the operation considerably more difficult to automate than simply moving standardized totes around a fulfillment center.

Tetromino appears aimed directly at this problem.

The reported concept would use AI, robotics, automated storage, and sequencing technology to reduce manual package handling between induction into a delivery station and placement into the correct delivery flow.

That changes the automation question from “Can a robot move this package?” to something much more sophisticated:

Can an automated system determine where thousands of irregular packages should temporarily reside, continuously reorganize them, and release them in exactly the right sequence for hundreds of delivery routes?

That is a logistics orchestration problem as much as a robotics problem.

The Tetris Problem of Parcel Logistics

The Tetromino name is particularly appropriate. A tetromino is one of the geometric shapes used in the game Tetris, and last-mile logistics increasingly resembles a three-dimensional version of the same puzzle.

Packages arrive in different sizes and shapes. They belong to different routes. Routes leave at different times. Vehicle capacity is finite. And the sequence in which packages are loaded matters because the driver ultimately needs to retrieve them efficiently during the route.

One technology reportedly being evaluated in connection with Tetromino comes from logistics automation company Boxbot.

Boxbot’s system combines automated package storage with software that can sort, sequence, and retrieve parcels. The company describes applications specifically for last-mile delivery stations, including vehicle loading, order management, and wave dispatch, and advertises vehicle-loading performance improvements of as much as 10 times for its technology. That figure is Boxbot’s own performance claim rather than an Amazon projection.

The underlying concept is important regardless of the specific vendor.

Traditional parcel sortation answers the question: Where does this package go?

A more advanced system must answer several questions simultaneously: Where should this package be stored right now? When should it be retrieved? In what sequence should it reach the loading area? And how should that sequence change when the operating plan changes?

That requires the physical automation layer and the decision layer to work together.

Throughput Is Only Part of the Economics

The reported 2.5-times throughput target naturally attracts attention, but throughput alone may not be the biggest economic opportunity.

Amazon has repeatedly emphasized lowering its cost to serve by shortening transportation distances, reducing package touches, improving inventory placement, and increasing consolidation. The company continues to invest aggressively in robotics across its fulfillment and delivery operations. Amazon’s recent delivery-station robotics work provides a clear indication of the direction it is pursuing.

Delivery-station automation could extend the same operating philosophy into the final node of the network.

A highly automated station potentially provides several benefits simultaneously: greater throughput from the same building footprint, fewer manual package touches, more consistent route staging, shorter vehicle-loading windows, improved ergonomics, and better utilization of expensive last-mile assets.

The labor implications are more nuanced than simply saying robots will eliminate warehouse jobs. A highly automated facility should require less direct labor per package processed, particularly for repetitive sorting, staging, and handling activities. But Amazon has not publicly confirmed what Tetromino would mean for total staffing levels, and the company continues to describe its robotics strategy as one that complements employees.

Tetromino therefore looks less like an isolated robotics experiment and more like another step in a much longer automation roadmap.

The Industry Is Chasing the Same Problem

Amazon is not alone.

Parcel and transportation companies have increasingly turned their attention toward automating the irregular loading and unloading processes that historically resisted conventional robotics.

FedEx, for example, has worked with Dexterity AI on robots capable of loading trailers filled with packages of different sizes, shapes, materials, and weights. FedEx has described the use of AI-powered robotic systems as part of its broader effort to automate complex material-handling operations.

This represents a broader transition in warehouse automation.

The first generation of large-scale logistics robotics worked best when operations were redesigned around highly controlled environments. Goods-to-person systems, automated storage systems, conveyors, and autonomous mobile robots all benefited from structure.

AI-enabled robotics is increasingly being directed at the opposite problem: bringing automation into environments that cannot easily be standardized.

Parcel handling is one of the clearest examples.

Why Tetromino Matters

Project Tetromino may change substantially before Amazon builds a production facility. The reported capital plan — including an initial $103 million pilot and additional sites — should be treated cautiously because Amazon has explicitly said those figures and the associated roadmap do not represent its current plans.

But the direction is more significant than the timetable.

For much of the past decade, the automation race in e-commerce centered on fulfillment. The next competitive frontier is increasingly the movement between fulfillment and the customer’s door.

If Amazon can combine automated buffering, AI-based sequencing, robotic package handling, and tightly orchestrated vehicle loading, the delivery station becomes something different from today’s labor-intensive sort-and-stage operation.

It becomes an automated execution layer connecting the warehouse directly to the delivery route.

And that could ultimately be much more consequential than simply building another faster warehouse.

From Prompting to Persistent Decision Workflows in Supply Chain Operations

Published

on

By

Supply-chain AI is moving from episodic prompting toward persistent decision workflows. Repeated prompting can help an analyst solve a problem, but an operating capability must maintain context, monitor changing state, preserve decision logic, and connect recommendations to the work that follows.

A persistent decision workflow needs memory of the business object, the current plan, previous recommendations, overrides, policies, and outcomes. Without that continuity, users repeatedly reconstruct context and the model cannot reliably distinguish a new exception from a continuation of an old one. This persistence requirement becomes more important as the AI-agent execution model advances, because an agent cannot act safely if each interaction starts without durable operating state or prior decision context.

A mature design connects detection, context assembly, analysis, option generation, recommendation, approval, execution, and feedback. Some stages may use generative AI; others are better handled by optimization, rules, deterministic integrations, or human judgment. Persistence comes from the workflow and state model, not from the conversational interface.

The system should know what it may observe, recommend, prepare, execute, and escalate. Financial thresholds, customer impact, reversibility, confidence, and policy can determine the autonomy level. These controls make repeated decisions governable at scale.

ERP, planning, TMS, WMS, visibility, risk, and network platforms remain systems of record and execution; decision intelligence sits above and across them where context is assembled, tradeoffs are evaluated, actions are prioritized, and responses are coordinated. The persistent workflow therefore needs controlled write-back or action mechanisms, not only read access and summarization.

A decision workflow should record recommendations, human overrides, actions, and results. That creates an evidence base for improving rules, models, prompts, and autonomy thresholds. A chat transcript alone is not an operating learning system.

The architectural shift is from asking AI for help to designing a governed process in which intelligence participates continuously. That is a much stronger foundation for supply-chain decision support than repeated prompting.

Persistent decision workflows need memory and governance

A durable decision workflow has to preserve operating state across time. It should retain the event, relevant context, alternatives, constraints, prior decisions, approvals, overrides, actions, and outcomes so that the next step does not depend on a user reconstructing the problem in a new prompt. That persistence is what turns AI assistance into an operational capability.

Buyers should test continuity across handoffs. Can the system resume an unresolved decision after new data arrive? Can a different user see why an option was rejected? Can an agent act only within encoded authority? Can the resulting transaction be traced back to the evidence and rule that produced it? These are architecture questions, not user-interface questions.

Persistence changes the economics of decision support

When a workflow is persistent, the organization stops paying the same context-assembly cost every time a decision changes hands. New events can be evaluated against the existing state, prior alternatives remain visible, and approvals or overrides do not have to be reconstructed from email or chat history. That can reduce decision latency while improving traceability. It also creates a better foundation for automation because the system can distinguish a new decision from a continuation of an existing one. Buyers should therefore evaluate memory, state management, versioning, and auditability as operating capabilities rather than treating them as secondary AI features.

Why SKU Selection Can Make or Break an AS/RS Business Case

Why Sku Selection Can Make Or Break An As/rs Business Case

Automated Storage and Retrieval Systems (AS/RS) have become a cornerstone of modern warehouse automation strategies. Whether the technology involves shuttles, cube-based systems, cranes, or goods-to-person solutions, the business case is typically built around a common set of objectives: increasing throughput, reducing labor requirements, improving accuracy, and maximizing storage utilization. Yet one of the most important decisions in any AS/RS implementation often receives far less attention than the technology itself: SKU selection.

Companies frequently spend months evaluating vendors, software platforms, and automation architectures. However, even the most advanced AS/RS can fail to deliver expected returns if the wrong products are placed into the system. In many cases, the difference between a highly successful deployment and a disappointing investment comes down to a simple question: Which SKUs should be automated?

The Purpose of AS/RS Is Productivity, Not Storage

One of the most common misconceptions about AS/RS is that its primary purpose is to store inventory. While increased storage density is certainly a benefit, the real value of automation lies in improving warehouse productivity.

AS/RS creates value by reducing manual labor associated with inventory handling. Every automated retrieval eliminates walking, searching, traveling, and material movement. The more frequently a product is handled, the greater the opportunity for automation to generate measurable savings.

This is where SKU velocity becomes critical.

Not all inventory contributes equally to warehouse activity. In most distribution centers, a relatively small percentage of SKUs generates a disproportionately large percentage of order lines, picks, and replenishment activity. These high-velocity items create the majority of warehouse work and therefore present the greatest opportunity for automation.

Why High-Velocity SKUs Belong in AS/RS

The strongest AS/RS business cases are generally built around automating the products that move most frequently.

Consider two products:

SKU A is picked 2,000 times per week.

SKU B is picked 10 times per month.

Both consume storage space within the AS/RS, but only one generates meaningful operational value.

Every time SKU A is automatically retrieved, labor is eliminated and productivity improves. Over the course of a year, those savings accumulate rapidly. SKU B, on the other hand, occupies valuable automated storage capacity while contributing very little to throughput improvement or labor reduction.

Simply put, high-velocity SKUs produce the transactions that justify the investment.

When organizations prioritize their fastest-moving inventory for AS/RS storage, they maximize:

Labor savings

Pick productivity

Throughput performance

Equipment utilization

Return on investment

This is why leading warehouse operators often use ABC inventory analysis to determine AS/RS eligibility, with A-items receiving priority placement within the automated system.

The Hidden Cost of Selecting the Wrong SKUs

Many automation projects encounter challenges not because the technology underperforms, but because the SKU strategy was flawed from the start.

A common mistake is attempting to place too many slow-moving products into the AS/RS simply because capacity is available. While this may increase storage utilization, it often reduces economic utilization.

An AS/RS filled with low-velocity inventory can create several problems:

Lower Labor Savings

Products that rarely move generate few picking events. As a result, automation replaces little labor activity, weakening the original business case.

Reduced Throughput Benefits

System resources become occupied storing inventory that contributes minimally to order fulfillment activity, limiting the throughput impact of the investment.

Longer Payback Periods

If labor savings and productivity gains fall below projections, the expected payback period can extend significantly beyond the original ROI model.

Capacity Constraints

As demand grows, operators may discover that high-velocity items no longer have sufficient space within the AS/RS because slower-moving products are consuming capacity.

The technology itself may be performing exactly as designed, but the financial return can still disappoint.

Focus on Activity, Not SKU Count

One of the most important lessons for warehouse leaders is that AS/RS success should not be measured by the number of SKUs stored within the system.

Instead, it should be measured by the percentage of warehouse activity flowing through the system.

For example, placing 1,000 high-velocity SKUs into an AS/RS that captures 80% of total picking activity will typically generate greater value than storing 5,000 SKUs that account for only 40% of picks.

The goal is not to automate the greatest amount of inventory.

The goal is to automate the greatest amount of work.

That distinction has significant implications for system utilization and overall project economics.

The Importance of Continuous SKU Evaluation

SKU selection should not be treated as a one-time exercise conducted during system commissioning.

Demand patterns change. Product popularity shifts. New items are introduced while others decline.

As a result, warehouse operators should periodically re-evaluate which products belong inside the AS/RS. High-velocity inventory today may not be high-velocity inventory next year.

Organizations that continuously align automated storage capacity with current demand patterns are often able to sustain higher utilization rates and stronger ROI throughout the life of the system.

ROI strategy

Consider a simple ROI example. Assume a company invests $5 million in an AS/RS and expects to save $1 million annually through labor reduction and productivity improvements. The original business case assumes the system will handle 75 percent of warehouse picking activity.

If the company correctly slots high-velocity products into the system, the projected labor savings can be achieved, resulting in a payback period of approximately five years. However, if management fills a large portion of the AS/RS with slow-moving inventory, the system may only process 40 percent of warehouse picking activity. Annual savings could fall to $600,000, extending the payback period from 5 years to more than 8 years. The technology has not failed. The SKU strategy has.

Final Thoughts

AS/RS technology continues to play an increasingly important role in warehouse automation strategies. Yet successful implementations depend on much more than selecting the right hardware or software platform.

The most effective AS/RS deployments are built around careful SKU selection.

High-velocity products generate the majority of warehouse activity and therefore create the greatest opportunity for labor reduction, throughput improvement, and productivity gains. Conversely, filling automated systems with low-velocity inventory can significantly dilute returns and extend payback periods.

For warehouse and supply chain executives, the takeaway is straightforward: an AS/RS should be designed around activity, not occupancy. The objective is not simply to store products in an automated system. The objective is to automate the work that drives operational performance. In most facilities, that means ensuring the highest-velocity SKUs receive priority access to valuable AS/RS capacity.

The difference between a successful automation investment and an underperforming one may ultimately come down to a decision that appears deceptively simple: choosing the right SKUs.

What the Descartes Innovation Forum Said About the Next Phase of Logistics Execution

Published

on

By

After several days at the 2026 Descartes Innovation Forum, the clearest takeaway was not simply that artificial intelligence is coming to logistics. That part is already obvious. What stood out more was where the technology is moving and why it matters now.

Across the keynote, a transportation leadership panel, a Walmart Marketplace session, and a detailed discussion of carrier fraud, the same operating problem kept surfacing in different forms. Logistics organizations have more data, more applications, more connectivity, and increasingly more AI, but the real value comes when those capabilities help someone make a better decision or execute the next step faster, more reliably, and with the right controls in place.

That matters because the operating environment is not getting easier. Transportation capacity is tightening, rates and fuel costs remain under pressure, fraud and cargo theft are serious concerns, customer expectations continue to rise, and companies are being asked to improve productivity without adding equivalent labor. Against that backdrop, the most interesting technology at the Forum was not technology that simply explained what was happening. It was technology aimed directly at the work itself.

The Swivel-Chair Problem Is Still Real

Descartes opened the Forum with a problem that will sound familiar to anyone who has spent time inside transportation operations. Companies may have capable systems and extensive networks, yet much of the actual work still happens in the gaps between those systems.

Someone receives an email, opens a portal, checks a transportation system, moves to another application, sends a message, waits for a response, updates a record, and then starts the process again somewhere else. Descartes referred to this as the “swivel chair tax,” and the phrase worked because it described a problem technology has never fully eliminated.

The company’s answer is its Agent Control Plane, which is designed to expose capabilities from Descartes applications as skills that AI agents can use. As I covered earlier in Descartes Takes Agentic AI Into the Logistics Workflow at the Descartes Innovation Forum, Descartes was careful to distinguish that approach from a basic chat interface or a traditional workflow engine. The intent is to allow agents to work across applications and adapt as conditions change rather than simply follow a rigid sequence of predefined screens.

The live demonstration made the concept more tangible. Descartes followed an order across four representative companies—a retailer, freight forwarder, customs broker, and final-mile provider—with 15 Descartes products supporting 28 process steps behind the Agent Control Plane. Many of those steps happened without requiring a person to manually move information from one application to another.

What stood out to me was not the amount of automation. It was where Descartes chose not to automate.

At one point, an agent identified a carrier option that could save roughly 8 percent. The carrier, however, had a poor trust score, thin operating history, and other warning signs. Rather than make the lower-cost choice automatically, the system surfaced the decision for human review. The human declined the cheaper carrier.

That is a much more practical model for agentic AI in logistics than the idea of simply handing an operating process over to a machine. Descartes repeatedly described autonomy as a dial, not a switch. Agents have identities, their actions are logged, activity can be replayed, and organizations can determine which decisions require human approval.

The significance is straightforward. Once AI begins taking actions inside real operating processes, governance stops being an abstract IT issue and becomes part of the operating model.

The Market Is Making Better Execution More Valuable

The transportation leadership panel I moderated later in the Forum put that technology discussion into a much tougher operating context.

The freight market described by the panelists was not one of strong demand and easy growth. It was one in which relatively weak demand is colliding with meaningful reductions in capacity. One participant cited a decline in the number of trucking companies from roughly 340,000 to 282,000 and dry-van truckload rates up approximately 33 percent year over year. The larger point was that the conversation has shifted. Two years ago, shippers were largely focused on rates. Today, capacity availability and reliability matter much more.

That tighter environment also increases risk. When capacity is harder to find, there is greater temptation to use carriers that may not have passed the same diligence in a looser market. Panelists tied that pressure to growing concerns around freight fraud, cargo theft, safety, insurance, litigation, and carrier qualification.

As discussed in Transportation Leaders See AI Moving From Experiment to Operating Model at the Descartes Innovation Forum, the response is not simply to cut spending. Technology did not sound discretionary in this discussion. One participant described a single repetitive business activity being performed roughly 750,000 times per month, representing the equivalent of about 1,500 employee-hours per day. That is exactly the kind of workload where automation can move from being interesting to economically significant.

The panel also showed how quickly expectations around technology development are changing. Voice agents, email automation, operational workflows, data science, and agentic AI were all discussed as practical tools rather than distant possibilities. One participant described a proprietary TMS containing more than 30 million lines of code and roughly 2,000 database tables. A 12-person team working with AWS and Anthropic was then tasked with recreating the system using AI-assisted development and reportedly produced a replication in approximately six weeks.

Replicating a system is not the same as proving it in full production, so that example deserves some caution. Still, it shows how quickly the economics of software development may be changing.

Transportation technology has traditionally changed slowly because systems were complex, deeply integrated, and expensive to modify. AI may compress that cycle dramatically. For transportation leaders, that creates an interesting tension: the operating environment is getting harder at the same time that the technology available to respond to it is improving faster.

Walmart Brought the Conversation Back to the Customer

A Walmart Marketplace session provided a useful counterweight to the AI-heavy discussions elsewhere at the Forum. Bryce Caswell, Director of Ship with Walmart for Walmart Marketplace, focused on something much more basic: the customer promise.

Walmart described four foundations for marketplace success—assortment, listing quality, pricing, and shipping—and emphasized that the four are interdependent. Good assortment will not solve poor content. Good content will not offset uncompetitive pricing. And none of it matters if the seller cannot deliver the product when promised.

That may sound obvious, but it was one of the more useful reminders of the Forum. Logistics technology discussions can quickly become dominated by architecture, optimization, visibility, and AI. The customer evaluates something much simpler: did the order arrive when you said it would?

As I wrote in Walmart Is Turning Marketplace Logistics Into a Platform, Walmart’s emphasis was not simply on speed. Reliability and consistency mattered just as much. During holiday peaks, sellers were encouraged to protect inventory availability, leave enough time to move product into the fulfillment network, understand what they are promising, and then meet that promise.

The company is also trying to simplify the mechanics underneath that promise. Walmart Fulfillment Services provides pick, pack, and ship capabilities through Walmart’s fulfillment network, while its multi-channel model allows sellers to support multiple sales channels from a single inventory pool.

Ship with Walmart extends that logic into transportation by offering access to negotiated carrier rates, including national, regional, and LTL options, while adding certain protections around on-time delivery and lost shipments.

The larger point is that simplification has value only if it improves execution. Whether the tool is an AI agent or a fulfillment network, the objective is the same: remove unnecessary friction so people can focus on the decisions and exceptions that actually matter.

Fraud Changes the Meaning of Visibility

The Forum’s carrier fraud session added another layer to the discussion because it showed how operating data is being repurposed for trust.

Descartes demonstrated how MyCarrierPortal and MacroPoint can be used together to strengthen carrier vetting before a load is tendered. The process extends beyond checking insurance or basic carrier status. It can incorporate configurable risk assessments, tracking history, lane history, inspection information, validated users, equipment data, and driver-level tracking statistics.

That is a subtle but important shift in how transportation visibility data is used. Historically, tracking information primarily answered a familiar question: where is my load? Increasingly, that same information can help answer a different question: should I trust the party moving it?

The same theme runs through Descartes Expands Freight Fraud Prevention Across Carrier Vetting and Shipment Execution. Descartes showed how historical lane activity and tracking behavior can be used as additional carrier-vetting signals. Once a shipment is in transit, the Notification Center can surface route deviations and other exceptions that warrant attention without requiring someone to monitor every load manually.

ELD Plus adds another layer by allowing two tracking sources to be used within the same tracking session. If mobile-device data and telematics data begin to diverge, that mismatch becomes a signal that someone may need to investigate.

Carrier lookup goes further by combining information such as power units, active loads, tracking history, spoofing flags, and recent lane activity. The example used during the session was simple: if a carrier has 100 power units but appears to be active on 600 loads, that discrepancy may deserve a closer look.

More automation does not reduce the need for trust. It raises the stakes. If systems are going to make recommendations or take actions faster, the quality of the signals behind those decisions becomes even more important.

Execution Is Becoming the Real Battleground

Looking back across the Forum, I do not think the central story was simply AI. It was execution.

Descartes is trying to reduce the swivel-chair work that still exists between logistics applications and companies. Transportation leaders are looking for technology that can improve productivity and help them operate through a tighter, riskier freight market. Walmart is focused on simplifying fulfillment so sellers can keep the customer promise. Carrier-verification tools are turning tracking data into a source of trust as well as visibility.

Put together, that points to a broader shift in logistics technology. Software is moving closer to the actual transaction, the actual decision, and the actual exception. The value of that technology will increasingly be judged by whether it helps organizations act better, not simply see more.

The companies that benefit most will not necessarily be the ones with the most AI, the most dashboards, or the most data. They will be the ones that can connect intelligence to execution without losing control of the process.

For me, that was the real takeaway from the 2026 Descartes Innovation Forum. The next phase of logistics technology is not just about making systems smarter. It is about knowing when the system should act, when a person should decide, and how to make both work together fast enough to keep freight moving and the customer promise intact.
