Planning Under Pressure: How Resilient Teams Prepare When Demand Softens

Written by Marcus Grimm | Sep 24, 2025 1:17:06 PM

The warning lights are flashing.

The ISM Manufacturing PMI registered 48.7 in August, marking the sixth straight month of contraction. The Cass Freight Index shows freight shipments down 9.3% year over year. Major retailers, including Walmart and Target, have tempered Q4 outlooks, citing tighter consumer budgets.

For operations leaders, the pressure may feel new — or at least distant. Slower order books, tighter labor budgets, and rising pressure to cut costs without breaking service are returning themes. Some firms will grow through this moment because of their unique positioning. But for many, the market is shifting. And unlike the systemic shock of COVID-19, this downturn feels more like the structural pullbacks of 2008 and 2009.

That distinction matters. During the COVID-19 pandemic, speed was the differentiator. Today, judgment matters more. The volatility may appear similar, but the response must be more deliberate and informed by what history and research consistently demonstrate.

Coming out of the last major recession, Harvard Business Review analyzed 4,700 companies across three downturns and found a clear pattern: firms that focused solely on cost-cutting were far more likely to lag behind their peers in the rebound. The outperformers paired discipline with selective investment, especially in capabilities that strengthened decision-making.

That research is more relevant now than it’s been in decades. Many operations teams haven’t experienced a true, prolonged demand downturn in nearly 20 years. COVID disrupted supply chains, but it didn’t pressure demand in the same way. Much of the tooling and planning logic used today was built during a long expansion cycle. That cycle rewarded execution speed over structural resilience. This moment is different. It’s a chance to revisit what older, still-relevant research has been telling us all along.

This article outlines five research-backed blind spots that planning teams encounter during downturns, and shows how Decision Intelligence transforms those risks into repeatable, resilient decision systems. From scenario stress-testing to buffer balancing and maintenance prioritization, we’ll examine what the best-run companies do differently, and how modeling enables that discipline to scale.

Blind Spot 1: Optimizing for the Single Forecast

In downturns, many organizations double down on the forecast. They fine-tune spreadsheets, adjust parameters, and convince themselves that greater precision will stabilize the plan. However, forecasts fail most rapidly when markets are volatile. Research from the RAND Corporation and decades of scenario planning show that robust policies consistently outperform optimized plans under deep uncertainty. Companies that bet on a single number are usually betting wrong.

Resilient leaders plan across a range of futures, not just the expected case. They define divergent demand paths such as growth, contraction, and mixed volatility, and then evaluate their operating rules against all of them. The test is not “Does this plan work in one scenario?” It is “Does this policy hold up across many?” That shift, from optimization to robustness, is what separates organizations that stumble in recessions from those that adapt and rebound.

Decision Intelligence becomes indispensable in this context. Simulation and optimization models enable teams to encode real-world network-wide policies, such as transportation mode shifts, carrier bidding strategies, DC cut-off rules, and order release logic, and then stress-test them across dozens of demand and service scenarios. The output becomes a scenario library and robustness scorecard that teams can revisit as conditions shift. Instead of hoping the forecast is correct, leaders gain a reusable capability: a clear view of which policies consistently deliver stability in cost and service. 

Scenario-based modeling transforms strategic supply chain planning into a repeatable decision system. It protects service today and accelerates recovery tomorrow.

Blind Spot 2: Cutting Buffers Across the Board

When demand softens, it's common to attack every source of slack: inventory is driven down, overtime is eliminated, and schedules are packed to maximize utilization. On paper, leaders see efficiency gains. In practice, they remove the very buffers that absorb variability. Operations science teaches that inventory, capacity, or time must be able to absorb variation. Researchers at the Project Production Institute recently revisited the cycle time formula and showed how eliminating all buffer components significantly increases cycle time and compromises service under volatility.

A more effective approach is to rebalance buffers rather than removing them entirely. The key is to decide which buffer absorbs the shock based on your market conditions, cost of capital, and service commitments. In a downturn, it may make sense to reduce inventory while preserving some time or capacity. But those tradeoffs should be tested, not assumed.

Decision Intelligence makes that testing possible. Simulation models run alternate buffer mixes and quantify the impact on cycle time, fill rate, and utilization across multiple demand paths. The result is a buffer tradeoff map a reusable decision asset that operations and finance can review together. It reduces arguments, speeds approval, and protects service while lowering costs.

Blind Spot 3: Deferring Maintenance Without Risk Math

When workloads fall, it's common to defer preventive maintenance (PM) across both facilities and fleets. The logic is simple: save labor and spare parts now. However, the cost is reflected in the rebound. Assets that miss scheduled PM can fail when demand returns, extending downtime and slowing recovery.

Resilience research emphasizes two key metrics in this context: Time to Recover and Time to Survive. The proper maintenance decisions depend on an asset’s recovery profile and its role in the broader network. Instead of delaying everything, a more strategic approach prioritizes PM packages that shorten Time to Recover for the most critical nodes.

Decision Intelligence makes those tradeoffs visible. Reliability models and scenario simulations help teams compare the impact of performing PM now versus later, showing the expected impact on downtime, recovery speed, and service levels across multiple futures. The result is a prioritized PM plan that balances short-term savings with long-term readiness.

Blind Spot 4: Freezing Flexibility Investments

When budgets tighten, flexibility investments are often the first to go. Cross-training gets cut. Shift coverage stays rigid. On the surface, this appears to be a smart place to save. But research shows the opposite. Even small, well-targeted cross-training delivers most of the benefit of full flexibility.

Studies by operations researchers such as Hopp and Van Oyen have shown that chaining strategies, in which each worker is trained to cover one or two adjacent tasks, can yield significant gains in stability and throughput without requiring full coverage. Follow-up simulation work, including Nembhard’s, confirms that modest levels of cross-training often outperform broader strategies in systems facing variability or product mix changes.

Critically, these studies aren’t new. Rather, they were crafted in the aftermath of previous downturns like the ones many are sensing now. As such, this research is newly relevant. Most teams haven’t had to test their labor flexibility in a true demand-driven downturn in over a decade. The last 15 years have rewarded speed and standardization. Today requires something different.

Decision Intelligence makes these strategies operational. Through simulation, teams can quantify which cross-training links provide the greatest resilience lift for the lowest cost. These models reveal where response times improve, how labor can be flexed between stations, and how to redesign skill coverage without overbuilding. The result is a cross-training map your team can implement gradually, backed by clear logic and measurable impact.

Blind Spot 5: Treating Capital Choices as Now-or-Never

When markets slow, capital projects often get reduced to binary choices: move forward or cancel. Plants pause automation upgrades, shelve layout changes, or delay supplier onboarding. On paper, these moves look prudent. In practice, they eliminate option value. Once capital flexibility is gone, leaders are left with fewer levers to adapt as conditions evolve.

Research backs this up. Real Options Theory, developed in corporate finance and extended to operations strategy, shows that the ability to stage, defer, expand, or abandon investments has measurable value under uncertainty. In manufacturing and supply chain contexts, studies highlight how structured flexibility in capital allocation can protect firms during downturns while preserving the upside when recovery comes. Rather than locking into a single path, resilient firms design decision points into their capital plans.

Decision Intelligence brings that theory into practice. Models evaluate staged investment paths, compare costs under multiple demand futures, and identify triggers that determine whether to accelerate or pause. For example, a simulation might show that adding one conveyor section now, with a clear trigger to expand later, outperforms both full rollout and full cancellation across most scenarios. The output is a capital options map: a structured playbook that leaders can defend with finance, explain to boards, and adjust as conditions evolve.

This shift reframes capital planning. It is not about optimism or caution. It is about designing investments with the same robustness you expect from operational policies. Modeling makes those options visible, quantifiable, and reusable. That leaves organizations better positioned to navigate downturns — and faster to capture opportunities in recovery.

Why This Matters Now

The game has changed. After years of growth and a one-off COVID shock, operations teams now face a more familiar kind of slowdown. Many organizations haven’t managed through conditions like these in nearly two decades. The playbooks built for expansion and speed won’t carry leaders through this cycle.

This article outlined five blind spots that research has flagged for years: the risks of over-optimizing forecasts, cutting all buffers, deferring maintenance without risk math, freezing flexibility, and treating capital as a binary choice. Each one comes with a framework for making more resilient decisions in the face of uncertainty.

These frameworks have been tested before. They’ve outperformed in disruption. They haven’t always been easy to apply, but Decision Intelligence changes that. When leaders model these decisions, they turn strategy into scenario libraries, buffer maps, maintenance triggers, cross-training plans, and capital options.

The decisions ahead are yours. But they don’t have to be reactive, rushed, or isolated. The right models give structure to tough choices and create space for judgment.

With Decision Intelligence, your team can lead through change with clarity, build systems that withstand strain, and make every critical decision more deliberate, defendable, and resilient.
