The strategic turning point in procurement: The 7 Lean World Class® steps for end-to-end excellence

Summary

In the current economic context, characterized by geopolitical instability, rapid technological changes (Industry 4.0and the increasing complexity of products, the traditional function of procurement (procurement) has long surpassed its role as a mere “cost center.” Today, the purchasing department is recognized as an element strategic able to directly influence profitability, liquidity (cash inflow) and the ability to innovation of the company.

How can a company not only react to this scenario but transform it into a lasting competitive advantage? The answer lies in adopting a structured and rigorous approach: the Lean World Class® Procurement, a method that extends the principles of Lean Thinking and of World-Class Manufacturing (WCM) across the entire value chain, from suppliers to customers.

Maximize Profitability with the Leverage Effect: The Lean World Class® Approach to Procurement

To understand the importance of applying lean thinking to procurement, it is fundamental to analyze the specific weight of supply costs. In most manufacturing companies, spending on raw materials, components, and external services represents the cost item. more significant within the income statement.

This is where the concept of “Leverage effect” (or leverage effect):

1. Production cost: To increase profitability through production, significant efficiency improvements are necessary, often by reducing internal costs (labor, energy, processing costs). These improvements, while essential, tend to be incremental.
2. Cost of supply: Even a slight decrease in procurement costs results in a much more significant increase on operating profitability. For example, an 1% reduction in purchase costs can have an impact on the’EBIT (earnings before interest and taxes) is much higher than that of an equivalent percentage increase in revenue, especially in low-margin sectors.

In summary, focusing improvement efforts on the management and optimization of procurement costs allows for immediate and relevant profit increases. Not only that: acting on the cost of materials, reducing inventory, and optimizing payment terms has a direct and positive impact on cash inflow, providing vital liquidity for investment and growth.

From Lean Thinking to Lean World Class® Procurement: an end-to-end approach

The Lean World Class®, (Bonfiglioli Consulting's proprietary methodology), is the mature evolution of both Lean Thinking and World Class Manufacturing (WCM).

• The Lean Thinking focuses on creating customer value while reducing waste (change) along the entire value stream.
• The World-Class Manufacturing (WCM) it is a rigorous and methodological approach, based on managerial and technical pillars, historically focused on reducing transformation cost (Transformation costand operational within the factory perimeter (the approach “door-to-door”).

Lean World Class® procurement was born to fill a strategic gap: the need to extend the methodological rigor and measurable effectiveness of WCM outside the factory perimeter, applying it to the material cost and the entire supply chain management, transforming the approach into a model “end-to-end”.

The fundamental objective of Lean World Class® Procurement is to provide a “reliable compass” that translates the business strategy into concrete and measurable actions for cost reduction related to procurement, and at the same time increases resilience.

The Structure of Lean World Class® Procurement: Three Phases and Seven Steps to Excellence

The Lean World Class® Procurement approach is organized into an evolutionary path that develops through three main phases – Reactive, preventive, and proactive – and it is structured into seven steps (o steps) taking up the problem-solving logic typical of the WCM pillars.

Phase 1 – Reactive (focus on eliminating waste)

This initial phase aims to address and resolve existing critical issues, measuring and quantifying the losses generated by an inefficient procurement process.

Step 1: Analysis of critical factors and loss measurement

The starting point is the identification and quantification of losses associated with the procurement process. The focus is on the four fundamental KPIs:

• Quality Scrap, defects, rework due to non-conforming supplies.
• Delivery Delivery delays, missed deliveries, line interruptions.
• Cost unforeseen price variations, indirect costs, and TCO.
• Inventory excessive inventorychange in inventoryobsolescence.

This step involves the use of tools such as Supply Chain Cost Deployment to assign an economic value to each loss.

Step 2: Root Cause Determination and Countermeasures (Goal: Zero Defects)

Once losses are identified and quantified, lean methodology rigor (such as the 5 Whys or Ishikawa diagram) is used to trace the root causes of the problems. The focus is on studying the necessary countermeasures to aim for the goal of zero losses due to inefficiencies in the procurement process.

Step 3: Implementation of countermeasures and standardization

The defined countermeasures are implemented, and the formalization of the new operating standard begins. This includes the production of a new vendor list (qualified suppliers) and an initial vendor ranking (performance-based rating) that reflects the improvements achieved.

Phase 2 – Preventive (building a robust and strategic system)

The goal of the preventive phase is to transform supplier management from a reactive response to a problem into a strategic and proactive action, managing risks and opportunities before they arise.

Step 4 & 5: Strategic Analysis, Constraints, and Opportunities (Vendor Ranking Evolution)

These steps are dedicated to the in-depth analysis of all constraints and opportunities, both internal and external, to build a new, more efficient and resilient standard. Key tools in this phase are:

• Kraljic Matrix to segment the supplier base according to their impact on profit and supply risk, defining differentiated strategies (e.g., partnership, leverage, routine, bottleneck).
• Country Risk Analysis to diversify sources and increase system resilience.
• Advanced vendor rating the ranking is refined to include not only past performance but also the supplier's innovation capacity, flexibility, and adherence to lean principlessupplier development). This allows for the implementation of a true Strategic sourcing.

This phase is closely connected to the creation of a Business Continuity System (BCS) for procurement, which identifies, mitigates, and plans the response to potential supply risks.

Phase 3 – Proactive (digitization, expansion, and continuous improvement)

The proactive phase projects the company towards excellence, leveraging Industry 4.0 technologies and ensuring the system's sustainability over time.

Step 6: Digitalization of Processes (Industry 4.0 Technology)

To achieve maximum efficiency (minimum cost) in the procurement process, it is essential to implement digital integration tools. This includes automating order flows, using real-time monitoring platforms, supply traceability (e.g., with RFID), and data integration for visibility and responsiveness along the chain. Digitization drastically reduces “waiting muda” and “over-processing muda” (such as paper-based management or manual data entry).

Step 7: Extension of the Method to the Supply Chain and Continuous Improvement

The last step is the extension of the method. Lean World Class® Procurement cascading to all strategically important suppliers, encouraging them to adopt lean principles in turn. This generates a multiplier effect on overall supply chain costs, ensuring that the entire partner network operates leanly and efficiently. This is the principle of kaizen applied to procurement.

The Total Cost of Ownership (TCO) and the Importance of Quality

The common thread that ties together all the phases of Lean World Class® Procurement is the focus on Total Cost of Ownership. Knowing the total cost of a supply, going beyond the simple purchase price, is the crucial issue to address.

The Total Cost of Ownership include:

• Purchase price (agreed price).
• Transaction costs (order issuance, transportation).
• Operating costs (storage, inventory).
• Non-conformance costs (hidden costs): Scrap, rework, line stops, additional inspections.

The approach Lean World Class® Procurement places a strong emphasis on the analysis and attribution to different suppliers of a share of indirect costs generated by them, allowing an assessment of the burden overall of the supply agreement.

This analysis is strictly linked to the pillar of Quality Control del Lean World Class® : understanding the impact of supplier quality performance on Total Cost of Ownership is fundamental to making correct strategic decisions. Often, a supplier with a marginally higher purchase price, but with excellent quality and punctuality, generates a Total Cost of Ownership inferior to a supplier with a low price but a high incidence of hidden costs.

The competitive advantages of Lean World Class® Procurement: measurable results

Lean World Class® Procurement is not just a methodology for cost reduction, but a transformative journey that redefines how a company collaborates with the market and manages value.

The results that can be obtained from the adoption of Lean World Class® Procurement They are tangible and measurable, based on our consolidated experiences:

• Operating cost reduction can you get discounts between the 20% and 30%.
• Delivery punctuality improvement increases up to 95%.
• Reduction of operating cycles (lead time): demolitions up to 40%.
• Greater resilience and visibility: thanks to structured risk management and the digitalization of information flows.
• Greater value for the end customer e benefits derived from innovation adopted by suppliers.

The ultimate goal of Lean Procurement can be summarized in the slogan: “Spend less, spend better”. This is pursued through consumption optimization, standardization, simplification, process automation, and a profound awareness of actual business needs.

Defining and implementing the strategic procurement plan proactively, reducing indirect supply costs through digitalization, and developing suppliers with logic and method are the steps that lead the company towards’operational excellence in the purchasing process. In an increasingly uncertain world, Lean World Class® Procurement is the necessary guide to navigate towards the true north of corporate competitiveness.
