Your Supply Chain and Logistics Stories for the Week:

Five Transportation Technology Trends Reshaping Supply Chains in 2026

The transportation landscape in 2026 has transitioned from fragmented pilot programs to a model of connected execution, where Jim Frazer notes that integrated architectures are replacing isolated tools. This shift is characterized by a move from simple optimization to full orchestration linking transportation data with inventory and labor, and the evolution of TMS platforms into AI-driven decisioning tools that prioritize real-time adjustments over static planning. Furthermore, dock and yard operations are now synchronized as part of a holistic workflow. At the same time, autonomous technology has matured into a pragmatic phase, deploying selectively within bounded corridors and specific last-mile niches where the economic and regulatory conditions are most favorable.

Rivian and Redwood Materials Announce Energy Storage Partnership for Manufacturing

From data centers to car manufacturing, Redwood Materials announced another major partnership utilizing its battery storage systems. This week, American automotive and technology company Rivian announced a partnership to deploy pioneering battery energy storage at Rivian’s Normal, Illinois, manufacturing facility. The plan is to use more than 100 second-life Rivian battery packs to unlock 10 megawatt-hours of dispatchable energy during peak demand times, to reduce energy costs and grid load. Redwood will integrate the batteries into a Redwood Energy system, supported by the company’s Redwood Pack Manager technology, allowing their stored energy to be used on-site by Rivian’s plant in Normal.

The Future of Warehousing: Newest Podcast Episode

Gaven Simon and Jeremy Hudson sit down for a candid conversation about the future of warehousing. The conversation touches upon automation within the warehouse, labor retention, packaging, sustainability, and WMS. Jeremy shares his experience in the logistics industry, spanning from riding around on a golf cart dropping off cups to implementing WMS software at a major warehouse operation. The episode ends with a discussion about retaining employees by improving the work atmosphere and leveraging software to reduce repetitive tasks.

Why Sulfuric Acid is Emerging as a Supply Chain Constraint in Copper

While typically viewed as a secondary industrial input, sulfuric acid is now a primary supply chain constraint due to a combination of geopolitical disruptions in the Middle East, China’s recent export restrictions, and tightening smelter economics. This shift creates a dual-threat environment: leach operators face rising procurement costs and inventory risks, while smelters lose critical byproduct revenue that previously cushioned weak refining charges. For supply chain leaders, this serves as a critical reminder that resilience requires looking beyond headline commodities to the “enabling inputs” that can quietly destabilize entire production systems when trade flows shift.

Home Depot Acquires Warehouse Tech Firm to Boost Fulfillment Strategy

The Home Depot has acquired warehouse technology firm Simpl Automation to bolster its distribution speed and efficiency. This move follows a successful pilot at the retailer’s Locust Grove, Georgia, facility, where the technology—which includes automated storage and retrieval systems as well as vertical lift modules—led to faster pick speeds and a reduction in manual product touches. By integrating these automated workflows, the company aims to improve worker safety and support its broader strategy of offering same-day and next-day delivery by housing high-demand products closer to customers. This acquisition aligns with a larger industry trend of major retailers like Walmart and Amazon investing heavily in mechatronics to streamline fulfillment networks.

Stellantis and Microsoft have announced a broad five-year collaboration spanning AI, cybersecurity, cloud modernization, and engineering. For supply chain leaders, the more important question is where measurable operational value will show up first.

Stellantis and Microsoft say they will co-develop more than 100 AI initiatives across customer care, product development, and operations as part of a five-year strategic collaboration. The announcement also includes AI-driven cybersecurity, Azure-based cloud modernization, and broader deployment of Copilot tools across the Stellantis workforce.

For supply chain and logistics leaders, the key signal is not the scale of the announcement alone. It is the potential for AI to improve predictive maintenance, support manufacturing performance, strengthen logistics coordination, and make operational data more accessible across the enterprise. Stellantis also says it is targeting a 60 percent reduction in datacenter footprint by 2029 through its Azure modernization effort.

The announcement is meaningful, but still broad. The real test will be execution: which workflows move first, where measurable gains appear, and whether the effort produces tangible improvements in uptime, responsiveness, and supply chain performance rather than remaining a large transformation program on paper. That is the part worth watching.

The post Stellantis and Microsoft Expand AI Collaboration Across Operations appeared first on Logistics Viewpoints.

Stockouts rarely result from a single forecast miss or delayed shipment. More often, they reflect small operating failures compounding across planning, sourcing, transportation, inventory, and execution.

Stockouts are often the clearest sign that the operation is less synchronized than leadership assumes. Many companies still treat them as isolated events. Planning points to forecast error. Procurement points to supplier inconsistency. Logistics points to inbound delays. Warehousing points to receiving or replenishment issues. Sales points to demand volatility. Each explanation may contain some truth. But when the same availability problems keep showing up, the real issue is usually broader: the operation is absorbing more variation than it is built to handle.

That is why shortages continue to appear even in companies with mature planning processes, modern enterprise systems, and experienced operators. The real question is not whether the business has planning, inventory targets, or supplier scorecards. It is whether those mechanisms are aligned tightly enough to absorb routine variability before it turns into a customer-facing problem.

A supply chain can be well run in pieces and still fail in coordination. That is often where the trouble starts.

The Problem Usually Starts Upstream

By the time a stockout becomes visible, the problem has usually been building for days or weeks. A DC cannot ship the order. A plant is missing a component. Customer service sees an unavailable item. But the root cause often began much earlier.

Demand signals may be lagging actual consumption. Supplier lead times may be drifting. Purchase orders may be placed against stale assumptions. Inbound transportation may no longer be performing to plan. Safety stock settings may still reflect a more stable operating environment. None of these problems needs to be severe on its own. But when several occur at once, the margin for error disappears quickly.

That is what makes persistent shortages so important diagnostically. They do not just mean demand exceeded supply. They often mean the business has lost its ability to recover gracefully from normal friction.

Forecast Error Is Often Overblamed

Forecasting deserves scrutiny, but it is too often treated as the main culprit because it is the easiest function to blame. Many stock availability failures occur in organizations where forecast accuracy is imperfect but still good enough to support acceptable service. The larger problem is that the rest of the operation is too brittle to tolerate normal forecast error.

No forecast will be exact. Demand shifts by channel, customer, geography, promotion, season, and timing. That is the operating environment. Strong supply chains are not defined by perfect forecasts. They are defined by how well the network responds when forecasts are inevitably wrong.

If replenishment cycles are slow, supplier response is rigid, transportation capacity is tight, and inventory policies are stale, even modest forecast misses can trigger outsized service failures. In that environment, forecast error becomes a convenient explanation for what is really an operating design problem.

Why Lead Time Variability Matters More Than Average Lead Time

Many organizations still build replenishment and inventory logic around average lead times. That works tolerably well in stable conditions, but stock availability problems are usually driven less by average performance than by variation around the average.

A supplier with a nominal 21-day lead time may not look problematic until orders begin arriving in 18 days one month and 31 days the next. A port-to-DC move that typically lands in five days becomes a service risk when it unpredictably stretches to nine. These fluctuations matter because inventory positioning decisions are often made with more confidence than the inbound environment justifies.

Many companies are still planning to the mean while operating in the variance. That gap shows up quickly in service performance.

Inventory Policy Is Frequently Out of Date

Safety stock, reorder points, min-max settings, and deployment logic are often treated as set-and-maintain decisions. In reality, they should move as operating conditions move. In many organizations, they do not.

A business may have changed its supplier base, freight modes, customer mix, SKU complexity, or fulfillment pattern without updating the inventory logic behind those changes. The result is a policy structure built for a supply chain that no longer exists.

This is one reason stockouts are often less about insufficient total inventory than about inventory held in the wrong place, against the wrong assumptions, or at the wrong levels. Some nodes carry excess. Others run exposed. Expedites rise. Service becomes unstable. The company concludes it needs more inventory when what it may really need is better inventory design and stronger parameter discipline.

Supplier Performance Problems Are Often Visible Too Late

Supplier scorecards can create the impression that the organization is monitoring supplier reliability closely. Sometimes it is. Often it is not monitoring the right things at the right level.

A monthly on-time metric may appear acceptable even while a critical supplier is becoming less predictable on a narrow but important subset of items. A fill-rate measure may hide growing volatility in order confirmations. Commercial reviews may focus on price and annual commitments while operational degradation builds underneath.

These failures often repeat not because suppliers collapse dramatically, but because their reliability erodes gradually and the buying organization is slow to respond. Lead times stretch. Flex capacity disappears. Communication weakens. Recovery speed declines.

Supplier management has to be operational, not just commercial. The key question is simple: are you measuring the parts of supplier performance that actually determine service reliability?

Transportation Execution Is a Major Driver

Many stockout discussions remain too planning-centric. That is a mistake. Transportation execution plays a much larger role in stock availability than many executive teams acknowledge.

An item can be forecast correctly, ordered on time, produced on time, and still go out of stock because the physical movement did not perform to plan. Appointment capacity tightens. Drayage slips. Linehaul schedules fail. Inbound receiving windows are missed. Yard congestion slows unloading. A shipment that is technically in the network is not yet usable inventory.

That means solving stock availability problems is not just a planning task. It is also a logistics execution task.

The Warehouse Can Amplify Upstream Instability

Distribution centers and plants are often expected to absorb variability created elsewhere. When inbound arrival patterns become inconsistent, receiving operations have to adjust. When order priorities change late, picking and replenishment teams scramble. When slotting is poor or cycle counting is weak, available inventory becomes harder to find and trust.

A warehouse may not have caused the service failure, but it can amplify it. Poor location accuracy, delayed putaway, weak replenishment discipline, and limited visibility to constrained inventory all widen the gap between inventory ownership on paper and inventory availability in execution.

Some of these problems are physical, not statistical. That matters more than many teams admit.

Functional Silos Keep the Problem Alive

These problems persist in part because they sit at the intersection of multiple functions while ownership remains fragmented. Planning owns forecast and replenishment logic. Procurement owns supplier relationships. Transportation owns movement. Warehouse teams own execution. Sales shapes demand. Finance pressures inventory levels. Customer service sees the final failure.

Without shared accountability, each function can improve locally while the end-to-end result remains unstable. Planning reduces inventory. Procurement negotiates harder terms. Transportation cuts cost. Warehousing protects labor efficiency. Each decision may be rational within its own frame. Collectively, they can increase service fragility.

Reducing stockouts requires a more integrated operating view. Service failures usually emerge from the interaction of functional decisions, not from one isolated mistake.

Chronic Expedites Are a Warning Sign

Few indicators reveal stock availability risk more clearly than chronic expediting. When expedites become normal, the organization is signaling that its standard operating model is no longer aligned to actual demand and supply conditions.

Expediting has its place. But when it becomes routine, it is usually masking deeper structural problems: poor parameter settings, unreliable suppliers, weak inbound coordination, insufficient visibility to risk, or slow internal decision-making.

Expedites create the illusion of recovery. They solve the immediate issue while allowing the underlying conditions to remain untouched. That is not resilience. It is operational drift.

Good Companies Sometimes Normalize the Wrong Things

Perhaps the most important reason good supply chains still suffer these failures is cultural. Capable organizations can become very good at managing around friction. Teams work hard. Planners intervene constantly. Expediters rescue priority orders. Customer service smooths over failures. Leaders see committed people keeping the business moving and conclude the system is functioning better than it is.

Organizations can normalize recurring pain. They come to see stockouts, expedites, manual reallocations, short-term fixes, and emergency calls as part of the cost of doing business. Once that happens, the operation stops treating them as a design flaw and starts treating them as background noise.

That is dangerous because these failures are rarely just a service problem. They consume management attention, increase cost-to-serve, distort priorities, erode trust in planning, strain supplier relationships, and create hidden inefficiencies throughout the network.

What Leaders Should Examine First

When shortages recur, the right response is not to ask only whether the forecast was wrong or whether inventory levels should rise. Those questions matter, but they are too narrow.

A better line of inquiry is operational: Has lead time variability increased, even if average lead time has not? Are inventory policies still calibrated to the current network and service model? Where is inbound execution failing between shipment milestone and usable stock? Which suppliers are becoming less predictable at the item or lane level? How often is the business relying on expedites to preserve service? How much inventory is recorded but not practically available?

Those questions usually reveal whether the problem is episodic or systemic. In many companies, the answer is clear.

Final Thought

These stockouts are rarely random. In most cases, they are the visible expression of weak coordination across planning, sourcing, transportation, inventory, and execution. Companies that treat them as isolated events will keep fighting the same problem.

Companies that treat them as a structural signal have a better chance of fixing them. That requires more than another forecast review or one more dashboard. It requires tracing how demand, supply, transportation, inventory, and execution actually interact under real operating conditions.

That is where the problem lives. And that is where it has to be solved.
