About this Presentation
Brunello Menicucci starts with a familiar shop-floor paradox: machines are running, people are busy, work-in-process is everywhere, and deliveries are still late. The two instinctive responses — add more resources or optimize every department — often fail because the underlying issue is not total capacity but flow. Menicucci proposes testing that hypothesis using observable effects. If capacity were the true problem, lead times and the constraint should be relatively predictable. When flow is the problem, similar orders complete in wildly different times, the “crisis station” shifts from week to week, and expediting becomes routine. He identifies two forces behind the problem: local optimization and variability. Maximizing utilization or OEE at every station creates work that the system does not need yet, increasing WIP and delaying delivery. Even without utilization pressure, natural variation across dependent steps creates queues because gains are lost while delays compound. Standard MRP and ERP logic, he argues, typically treats resources too independently and does not distinguish the one resource that governs overall output. The proposed production response is Simplified Drum-Buffer-Rope. When most plants have more capacity than orders, S-DBR can deliberately treat the market as the constraint. Release is then controlled by the drum’s pace rather than by whether a job is merely ready to start. The deck states that this release discipline can reduce WIP by roughly 30% to 40%, while time buffers and Buffer Management replace gut-feel expediting with clear red/amber/green priorities. A critical behavior change is to stop treating all idle time as waste. Menicucci then offers his own interpretation — explicitly identified as his personal reading rather than a claim from the literature — that a production floor and a project network follow the same underlying logic. He maps the drum to the Critical Chain, production buffers to feeding/project buffers, and rope-based release to staggered project starts. He also marks the boundary: a production drum can move outside the plant when the market is the constraint, while a project Critical Chain remains structural inside the defined network. The session concludes that interdependent systems under variability require the same three moves: identify the pace-setter, protect it with time, and control what enters so the system is not overwhelmed.
What Will You Learn
To help you get the most value from this session, we’ve highlighted a few key points. These takeaways capture the main ideas and practical insights from the presentation, making it easier for you to review, reflect, and apply what you’ve learned.
How to distinguish a true capacity problem from a flow problem by examining lead-time variability, whether the constraint remains stationary, and the level of recurring expediting.
Why local optimization and variability create late delivery even when total capacity is available: utilization pressure builds unnecessary WIP, while delays compound across dependent steps.
How Simplified Drum-Buffer-Rope controls release, protects the pace-setter with time buffers, and uses Buffer Management to prioritize action instead of maximizing every resource or relying on firefighting.
How Menicucci maps S-DBR and CCPM as two vocabularies for similar system logic — constraint/critical chain, buffers, and release control — while explicitly recognizing an important boundary: the production drum can be the external market, but the Critical Chain remains structural within the project network.
Instructor(s)
Brunello Menicucci
Most consultants advise organizations from the outside. Brunello Menicucci brings a different perspective, having spent more than 40 years working inside factories, warehouses, finance departments, and boardrooms.
Brunello began his career at the age of 20 in a local shoe factory, where he managed finance and accounting. Working within a real production environment—observing how orders flowed, where work became delayed, and how cash moved through the business—shaped his understanding of organizations and influenced everything that followed.
A few years later, he joined a small housewares distributor, again working in finance. After completing a COBOL II course and recognizing the potential of business software, Brunello moved to an IT company that installed and supported enterprise resource planning systems.
Over the next six years, he worked inside marble companies, textile mills, woodworking businesses, paper factories, and many other production environments. His role went beyond installing software. Each implementation required a detailed understanding of a new industry, its operational constraints, and the ways money and materials moved through the system.
He later co-founded a marketing company at a time when the internet was not yet widely available to businesses. The company used early bulletin board systems to collect market intelligence, providing what would now be described as an early-stage information service.
His next role was with a national IT distributor, where he managed marketing for several large cash-and-carry stores. He then helped develop an entirely new distribution channel: a network of independent local stores operating under a national brand.
Moving into general management, Brunello joined a paper company as General Manager. There, he helped build the EcoCopia brand of A4 paper from the ground up and secured distribution through Esselunga, Coop Italia, and HP Europe. Working with major retail buyers and a multinational company provided practical lessons in throughput, market access, and commercial constraints that could not have been learned from a textbook.
He was subsequently involved in the turnaround of an office furniture company owned by Banca Intesa. After joining as General Manager, he became CEO and led the business back to profitability before it was acquired. The experience reinforced the importance of understanding system-wide consequences, avoiding local optimization, and recognizing that the true constraint is rarely where people initially expect to find it.
His final corporate role was as a board member and finance leader for one of Italy’s most prominent Apple distributors. During his three years with the company, revenue increased from €80 million to €210 million. Managing growth at that pace placed every process, person, and assumption under pressure and provided lessons that could only be gained through direct experience.
In 2012, after working inside organizations of many different sizes and across a wide range of industries, Brunello established his own consulting practice.
