Tariffs are on… then off, rising… then falling. As supply chain disruptions grow, end-to-end supply chain management, demand planning, and financial forecasting become considerably more complex.
Even companies with advanced Sales and Operations Planning (S&OP) capabilities find that traditional processes alone can’t keep up. The problem isn’t just speed—it’s accuracy. When fundamental demand and supply inputs constantly shift, even the most rigorous S&OP models begin to erode.
To succeed, executives must ensure their organizations move beyond reactive adjustments. By embedding supply chain disruption and tariff impact modeling, real-time visibility, and data-driven analytics into their S&OP process, companies can turn volatility into a competitive advantage through planning and forecasting agility.
Laying the foundation: Fixing data at the core of S&OP
In our experience, many companies have focused on processes and technology to address supply chain disruptions. Current conditions are exposing the limits of these levers. At its core, S&OP requires a robust, wide, and accurate data foundation to unlock value.
Even with the best planning tools and processes, companies will struggle if the data feeding those systems is unreliable. Companies that shift their investments to address demand and supply data challenges can expect rapid and tangible financial improvements.
Demand data cleanup
One of the biggest obstacles in demand planning is noise, especially from one-time purchases such as promotions, project orders, or new product launches. By separating these from recurring demand, companies can improve forecast accuracy and reduce inventory bloat.
For example, we helped a large manufacturer significantly reduce excess inventory by distinguishing between recurring business and unique project orders using CRM and sales data analysis. Separating this demand into buckets allowed forecasting on recurring business only, significantly reducing excess inventory by eliminating forecasts from one-time purchases.
In another case, a company producing highly engineered products began aggregating demand by common component units, enabling forecasting for the first time and improving stock availability on major project orders.
Supply data accuracy
Clean Bills of Material (BOM) are essential to accurate supply planning.
We build tools to compare consumption to projected usage and drive improvements in BOM quality. This process helps quickly balance working capital by identifying excess purchases for raw materials. We used this method for a food processing company to highlight shortages of packaging materials that were causing line stoppages.
For capacity planning and routing, modeling actual production output compared to the projected production output can identify gaps in the rates/routes used. This data can be used to quickly find the real bottlenecks in the manufacturing process and drive improvements. For an industrial manufacturer, we used this approach to help demonstrate an overloaded work center. We highlighted options for relieving backlogs in their production through outsourcing and updated routings. Within months, the backlog was eliminated, production was opened up, and the customer fill rate improved.
Companies typically understate the cost of extra inventory they hold due to a supplier’s poor performance. Integrating ERP, WMS, and TMS data gives a clearer picture of supplier reliability and enables smarter sourcing decisions.
These examples are meant to illustrate some of the moves companies can make, but the headline is that the best S&OP processes in the world can’t address volatility without validated and clean data.
With this in mind, we can now examine key demand and supply strategies to mitigate disruption while considering the pivotal role that data can play in the success of these approaches.
Rethinking demand planning: From forecasting to sensing
Traditional demand planning relies heavily on historical data. But in a tariff-driven world, yesterday’s data may not predict tomorrow’s outcomes. Demand becomes increasingly volatile as customers pull forward orders or shift preferences, particularly for mature products. Supply shortages can trigger significant product mix changes as buyers turn to alternative vendors, disrupting production plans. Traditional demand signals, like interest rate changes, may also lose reliability as consumer behavior becomes harder to predict.
Demand planners must shift toward a more dynamic, real-time, scenario-driven, and data-driven approach.
Key demand strategies:
Tariffs disrupt more than just demand—they fundamentally challenge sourcing, manufacturing, and logistics operations. Many companies scramble to build inventory ahead of tariff deadlines or shift suppliers to avoid cost increases, leading to cascading effects.
Sourcing becomes volatile as new supplier relationships create temporary demand spikes followed by sharp drop-offs, straining the vendor base. Logistics slow down due to rerouted shipments, customs delays, and border inspections, just as companies try to flex capacity. Tariffs can also spike working capital needs, stressing operations. Meanwhile, regulatory complexity increases, with constant updates to documentation, HTS codes, and exclusion filings delaying critical components.
Key supply strategies:
Go deeper, and consider more variables and options for each of those variables. Model different tariff rates (e.g., 10% vs 25%) on key components to determine the impact on lead time, cost, and capacity utilization. Evaluate the effect of increased transit times and rates on your business. With disruptions like the Red Sea Crisis adding 14-21 days to transit from Asia to Europe or U.S. East Coast destinations, what impact would this have on product availability? What if key suppliers in another country (Vietnam, for example) went out of business due to trade disruptions?
What can you expect with modernized and data-driven S&OP?
Companies that closely examine the data supporting their S&OP approach to handle supply chain volatility better can expect the following benefits:
Turn uncertainty into a competitive advantage
Tariffs won’t stop shifting anytime soon. The companies that win in this environment won’t just be the fastest—they’ll be the smartest. By evolving S&OP processes to include scenario modeling, real-time visibility, and clean foundational data, businesses can move from reactive firefighting to proactive planning.
Now is the time to act. AlixPartners’ S&OP team helps organizations build the digital tools and processes needed to thrive in this new era of uncertainty, turning complexity into clarity and disruption into opportunity.
