Driving Operational Excellence - Successful Lean Six Sigma Secrets
to Improve the Bottom Line;
MetaOps Publishing, LLC, 2010. Chapter 19, "Lean Six Sigma for a Leaner
Supply Chain: A Focus on Analytical Tools", Steve Cimorelli, CFPIM
If you take 24 lean six sigma gurus and ask them to reveal their most closely-guarded secrets, to uncover their most valuable tips, techniques, and tactics for creating lean speed and six sigma quality in any organization, what would these experts give to you? They would give you this book.
Quoting from the book's introduction, in chapter 19 Steve Cimorelli "presents advanced statistical techniques and tools in an easily understandable format to help you identify the critical areas and weaknesses in your supply chain processes. Steve demonstrates a comprehensive formula any organization can use to reliably and accurately identify problems and then implement successful solutions that drive results to the bottom line." This "formula" is the Six Sigma DMAIC process: Define, Measure, Analyze, Improve and Control; presented as a real-world case study.
Kanban For The Supply Chain; Steve Cimorelli,
CFPIM, Productivity Press, 2006.
This workbook is for manufacturing supply chain management (SCM) professionals who are ready to move beyond MRP to improve their inventory turns, manufacturing productivity and profitability. It provides SCM teams with a roadmap for installing fundamental kanban techniques through an iterative process of planning, adjusting, and executing, keeping inventory levels synchronized with demand and the supply chain synchronized with actual production. The workbook includes a CD with training slides outlining each chapter, allowing the kanban implementation leader to guide the team in the step-by-step process and to reinforce key lessons and action steps along the way.
Handbook of Manufacturing Engineering; Marcel Dekker, Inc., 1996. Chapter 11, "Control of Production and Materials", Steve Cimorelli with Greg Chandler.
This chapter, spanning nearly 70 pages, discusses a full range of production and inventory control concepts including planning, scheduling, execution and control. It is organized into the following sub-sections:
11.0 Introduction to Control of Production and Materials
11.1 Capacity Planning and Simulation (Greg Chandler)
11.4 Theory of Constraints
11.5 Material Requirements Planning (MRP) Systems
11.6 Inventory Management
The full handbook provides single-source coverage on the full range of activities that meet the manufacturing engineering process, including management, product and process design, tooling, equipment selection, facility planning and layout, plant construction, materials handling and storage, method analysis, time standards, and production control. The text examines every topic involved with product and factory development, parts fabrication, and assembly processes.

RMC Newsletter; University of Tennessee, Reliability and Maintainability Center, April 2011, Pages 3-5, "Optimizing MRO Inventory", Steve Cimorelli, CFPIM.
This article builds on the theme of data cleansing as a means of ensuring that MRO inventory investment is optimized. Key factors include mean time between failures (MTBF), reliability of suppliers, and variability of demand for operating supplies, all of which require accurate data to properly analyze their impacts. A statistical data cleansing approach is presented here, based upon a process of determining a "statistical outlier" threshold for each item, then eliminating or replacing outlier data points in the data stream. The process can be applied to a variety of data streams, yielding similar benefits in quality processes, maintenance applications, and many other arenas.

APICS Magazine cover story, January 2002, "Reduced Demand; how it affects kanban and average inventory - and what to do about it", Steve Cimorelli, CFPIM.
This article was originally written in response to the recession which began in 2001 following the burst of the tech bubble and subsequent terror attacks of 9/11. The economic conditions of 2009 are strikingly similar, or worse, and the advice presented in this article is as applicable now as it was seven years ago.
The article examines the need to synchronize inventory levels to expected demand, and the impacts of not doing so. It also presents strategies for executing inventory reduction through a series of internal and supply chain actions such as targeting reductions in supplier lead times and lot sizes.
APICS Magazine cover story, January 2010, "Anticipating the Reemergence of Demand - How to best use lot sizing in the economic recovery", Steve Cimorelli, CFPIM.

Optimizing Inventory for On-Time Delivery; Steve Cimorelli: Presents a statistical approach for cleansing demand history data to remove spikes which are unlikely to recur. Using the resulting data stream allows inventory optimization processes to be truly optimized, improving both inventory performance and on-time delivery.
Manufacturing Lot Sizing; Steve Cimorelli: Examines the debate between Lean advocates and traditional manufacturing management thought regarding the progression towards zero setup and lot sizes of one.
A Global Inventory Planning Foundation; Steve Cimorelli: Discusses foundational concepts of sound inventory planning practice, including demand planning, ABC classification, statistical safety stock processes and potential pitfalls. The paper then outlines a path forward for global companies to identify best-practices and standardize on them to improve customer service levels, inventory turns and profitability.
