The “safety stock vs flow” debate is reshaping supply chain strategies. Traditionally, companies stocked up on safety inventory, thinking it would boost service levels. However, this often leads to surplus inventory without guaranteed customer satisfaction improvements.
Flow-based, demand-driven models offer a new perspective, focusing on aligning inventory with actual demand rather than forecasts. This shift promises better service with less stock, simplified operations, and influential meeting of market demands.
Safety Stock vs. Flow: Navigating the Shift to Demand-Driven Models
In Advanced Planning Systems, a longstanding belief has been that companies need more safety stock to boost service levels. This mindset, deeply rooted in forecast-driven MRP methods, suggests that increasing inventory is vital to better service.
However, this strategy can lead companies to accumulate stock, hoping for service improvements that often don’t materialize. The result is a cycle of rising inventory levels without the anticipated benefits, challenging the effectiveness of traditional approaches.
The Crucial Role of Forecasting in Inventory Management
Advanced forecasting models aim to manage demand and supply fluctuations by minimizing errors in forecasts and lead times. This approach is supposed to offset the need for more safety stock. However, improving forecast accuracy and reducing lead time variability is a significant challenge for many companies.
As a result, as businesses strive for higher service levels, they often face an unavoidable increase in safety stock. This rise is a direct outcome of the basic calculations behind their strategies, underscoring the complexities of balancing inventory management with the goal of improved service delivery.
The Shift from Forecast-Based to Demand-Driven Approaches
A significant shift in inventory management is moving from the traditional forecast-driven MRP models to the modern Demand-Driven Operating Model (DDOM). DDOM stands out for its focus on a flow-based methodology guided by the principle known as Plossl’s Law. This law states, “Increasing flow leads to enhanced service levels and necessitates less inventory,” offering a promising solution for businesses.
This approach is appealing because it promises improved service levels and lower inventory requirements without perfecting forecast accuracy or supplier performance. It suggests a more straightforward, flow-focused strategy can lead to significant operational improvements, departing from conventional practices that rely heavily on forecasting and stockpiling safety inventory.
Case Studies: The Proof in the Demand-Driven Pudding
The effectiveness of demand-driven models is not just theoretical; real-world success stories confirm their value. For instance, companies such as Sames Kremlin, Protea Chemicals, and CCBA have switched, experiencing inventory reductions and service level improvements. They achieved these results without the need to eliminate forecast errors.
These case studies showcased at Demand Driven World 2019 prove the benefits of adopting a flow-based approach. By focusing on the actual flow of goods rather than predictive forecasting, these companies have streamlined their operations, illustrating the practical impact of demand-driven strategies.
Conclusion: A Paradigm Shift Worth Considering
The transition from traditional safety stock methods to flow-based strategies marks a profound change in supply chain management, moving towards a more agile, efficient, and responsive system. This shift challenges the old ways of thinking, highlighting the limitations of relying solely on forecasts and safety stock to manage supply chains.
The demand-driven model stands out as a solution for modern challenges, focusing on improving service levels by optimizing the flow of goods instead of stockpiling inventory. This approach encourages companies to reconsider their current practices and adopt strategies that better meet the rapid changes and demands of the current market landscape.

Leadership: The Catalyst for Change
The journey to becoming demand-driven is complex, requiring a visionary leader who dares to challenge the status quo. This leader must navigate the company through skepticism and resistance, advocating for a paradigm shift towards a Demand-driven model. Their role is critical in aligning executive support, facilitating cross-departmental collaboration, and ensuring the organization’s commitment to this transformative journey.
Before you start, you need a strong leader who does not mind lonely places.
“Leading innovation can be a uniquely lonely and unpopular thing because most of the time, you must stand by yourself saying: Everybody sees the world this way. I see the world another way!”
Christopher Galvin
This perspective underscores the inherent challenges and isolation that can accompany leading transformative change within an organization. The path to becoming demand-driven demands the courage to innovate and the resilience to stand firm in the face of doubt and opposition. It’s about seeing beyond the current state to a future where the supply chain operates on flow, efficiency, and responsiveness principles, driven by actual demand rather than forecasts.

The Demand Driven Material Requirements Planning (DDMRP) method has revolutionized supply chain management by combining several well-established methodologies. This approach enhances responsiveness, reduces inventory, and improves service levels in today’s volatile market. This article breaks down the DDMRP method into five manageable steps to help you understand and implement this powerful strategy in your supply chain operations.
Origins and Aims of the DDMRP Method
The DDMRP method, evolving from decades-old Material Requirement Planning (MRP) principles, introduces a demand-driven framework that adapts to the modern, volatile supply chain landscape. DDMRP targets optimal stock levels and enhanced responsiveness to market changes by focusing on strategic inventory positioning and dynamic adjustments.
Overcoming MRP Limitations
Traditional MRPs struggle to balance customer service with inventory levels, often resulting in bimodal inventory distribution. This can lead to excessive stock in some areas and shortages in others, necessitating costly last-minute interventions. DDMRP’s innovative approach targets these inefficiencies, enabling a more stable and efficient supply chain management process.
The Five Pillars of DDMRP:
1. Strategic Inventory Positioning
The first step in DDMRP involves identifying strategic locations within the supply chain to place buffers. Customer lead time expectations and variability at each point guide this decision. Strategic positioning helps absorb fluctuations, ensuring a smoother flow of materials.
2. Buffer Sizing
Buffers in DDMRP are segmented into three zones—green, yellow, and red—each serving a specific purpose. The green zone dictates the normal replenishment cycle, yellow indicates the lead time consumption, and red is designed to absorb variability, differing from traditional safety stock concepts. These zones are dynamically sized based on average daily consumption and lead time.
3. Dynamic Adjustment
Given the ever-changing nature of supply chains, DDMRP buffers require regular adjustments. These adjustments are both calculated (based on daily consumption changes) and planned (accounting for known future events) to ensure buffers remain aligned with current market conditions.
4. Demand-Driven Planning
DDMRP utilizes the “Net Flow Equation” to determine when replenishment orders should be triggered. This simplifies the planner’s job by clearly indicating which items need immediate attention based on their current buffer status, thus prioritizing actions effectively.
5. Visible and Collaborative Execution
The final step involves maintaining real-time visibility and collaboration throughout the execution phase. DDMRP provides execution alerts that help prioritize orders based on urgency, allowing planners to focus on the most critical tasks first.
Transforming Supply Chain Management with DDMRP
DDMRP marks a paradigm shift in supply chain management, moving from date-based planning to a more dynamic, demand-driven approach. By implementing these five steps, businesses can achieve a more resilient and responsive supply chain capable of adapting to the complexities of today’s market.
Conclusion
Implementing the DDMRP method in 5 steps can significantly enhance your supply chain’s responsiveness, reduce unnecessary inventory, and improve customer satisfaction. By following these steps, companies can navigate the complexities of modern supply chains more effectively, ensuring they remain competitive in a rapidly changing market.
