High Inventory, Supply Issues and Firefighting: 5 Levers for Better Supply Chain Performance

9. November 2026

In our day-to-day projects and in conversations with supply chain leaders, we keep seeing the same symptoms: high inventory, shortages of key products, unreliable delivery performance and a daily routine driven by escalations rather than control. At the same time, more data, reports and dashboards are available than ever before. Yet results often fall short of expectations.

Why do so many organizations fail to improve inventory, delivery performance and costs at the same time?

Our experience from numerous performance improvement projects shows that the real levers rarely lie in additional reports or new tools. What makes the difference is the mechanisms by which the supply chain is planned, managed and continuously developed. From these, we have derived five levers that consistently deliver measurable results in our projects.

Why supply chain performance often falls short of expectations

Most organizations invest heavily in transparency, standardization and new tools. Data is integrated, processes are harmonized, dashboards are built and new planning and analytics capabilities are created. The expectation behind this is understandable: lower inventory, better delivery performance, lower costs and less operational firefighting.

Reality check: why supply chain expectations are not met

In practice, however, a different question often arises: Are we making better decisions today than before? This is where the real reality check lies.

In our projects, we regularly encounter five causes that prevent the expected improvements in inventory, delivery performance and costs from materializing:

Silos remain in place

Sales, planning, procurement, production and logistics often pursue their own goals very consistently. Decisions are optimized locally, while the impact on inventory, service or costs shows up elsewhere.

Conflicting goals are not actively resolved

Reducing inventory while increasing availability. Cutting costs while improving service. Maximizing production utilization while staying flexible. These trade-offs need to be decided and managed deliberately.

Poor master data remains poor master data

An unrealistic replenishment lead time does not become more realistic through a migration. A poorly parameterized safety stock logic does not correct itself.

Responsibilities remain unclear

Who owns inventory? Who decides on service levels? Who reviews planning parameters? As long as these questions are not clearly answered, management often remains reactive.

Decision-making behavior does not change automatically

Inventory, delivery performance and costs are the result of thousands of decisions along the supply chain. Transparency lays the foundation, but real impact only comes from better decisions.

5 levers for better supply chain performance

What do successful companies do differently? 5 levers for better supply chain performance

1. Segment the supply chain

Different products, customers, sales channels and business models require different planning and control mechanisms. Segmentation defines the right inventory strategies, prioritization rules and service promises.

2. See planning as preparation

The purpose of planning is to prepare the organization for uncertainty. What matters is how sales, procurement, production and logistics jointly resolve conflicting goals, for example in the S&OP process.

3. Consistently translate planning into execution

Sooner or later, every plan is overtaken by reality. Supplier delays, demand fluctuations or production outages require clear rules and decision-making processes that work in practice.

4. Understand root causes instead of managing symptoms

KPIs clearly show that a problem exists. Only transparency about the root cause creates the basis for effective measures and decisions.

5. Master data is governance

Safety stocks, replenishment lead times, lot sizes and MRP parameters influence decisions on inventory, delivery performance and costs every day. That is why they need clear ownership and regular reviews.

Conclusion: performance is the result of decisions

Inventory, delivery performance and costs are not created in an ERP system. They are created by the decisions made every day along the supply chain. The five levers work together and lay the foundation for measurable improvements in supply chain performance.
