Introduction
The term “supply chain management” (SCM) entered the public domain when Keith Oliver, a consultant at Booz Allen Hamilton, used it in an interview with the Financial Times in 1982.1 The term was slow to take hold and the lexicon was slow to change. It gained currency in the mid-1990s, when a flurry of articles and books came out on the subject. In the late 1990s it rose to prominence as a management buzzword, and operations managers began to use it in their titles with increasing regularity.
The Council of Logistics Management hotly debated changing its name to the Council of Supply Chain Management in 2002, but rejected the idea at the time because many experts disagreed on the definition of SCM. Joel Sutherland, the board chair of the organisation at the time, said: “Surveys turned up hundreds of definitions.” He pointed out that the term was too broad and unclear, and could not be managed or measured. He said: “Logistics is part of the supply chain process as the Earth is part of the universe.” While we know the weight, the speed of rotation and the composition of the Earth, Sutherland pointed out that the universe is infinite in size and is expanding, and that 95% of it is made of a type of matter or energy that we cannot see or understand. After spending two more years developing an acceptable definition of SCM and deciding on a new name, the Council of Logistics Management ended up renaming itself in 2005 the Council of Supply Chain Management Professionals (CSCMP), but its official definition of SCM left many ambiguities unresolved by describing the set of disciplines that are evoked by the term rather than defining exactly what SCM is.2
Other professional associations – for example, APICS (the Association for Operations Management)3 and ISCEA (the International Supply Chain Education Alliance) – have since developed certification programmes in SCM. APICS’ certification is called the Certified in Supply Chain Practitioner, or CSCP, and ISCEA’S certification is called the Certified Supply Chain Manager (CSCM). Another, the Institute for Supply Management, is developing one called the Certified Practitioner in Supply Management (CPSM). However, since the CSCP and the CPSM certifications require practical experience as a prerequisite for certification, one may mistakenly infer that SCM must be learned on the job, like a trade, and cannot be codified into a clear body of knowledge that can be learned by students and general managers.
As of the writing of this book, there is no succinct definition of SCM, nor (more importantly) is there a definitive formula for executives and managers desiring to create shareholder value from the supply chain. So, while a new breed of companies such as Wal-Mart and Dell have demonstrated that managers can indeed use SCM for competitive advantage, most companies have found it difficult to replicate such success because the available resources fail to accurately and clearly provide a clear recipe for doing so. To most business people, SCM is still a broad term that covers many functions, including but not limited to purchasing, logistics, production, sales, customer service and engineering.
Conflicting definitions and interpretations
Use of the phrase “supply chain” has become widespread. According to Ohio State University’s 2004 career pattern survey in logistics, 27% of the respondents had the words “supply chain” in their title.
Yet many practitioners use key words like logistics, procurement, transportation and supply chain interchangeably and without a consistent hierarchy, confusing the supply chain’s role with respect to the other functions, and implying that everybody who works in any of those fields is a supply chain practitioner.
Academics have written extensively on the subject, but their definitions have at times been unclear or evasive. For example, one book defines supply chain management as “the integration and management of supply chain organizations through co-operative organizational relationships, effective business processes, and high levels of information sharing to create high-performing value systems that provide member organizations a sustainable competitive advantage.”4 Another sidesteps a definition in favour of an unquantifiable goal: “to achieve linkage and co-ordination between the processes of other entities in the pipeline”.5 Many others amalgamate principles from lean management, re-engineering, quality and manufacturing,6 which raises questions about whether SCM is part of these movements or something separate, and if so, where the overlap is.
Practitioners’ books are typically biased towards the functions in which the author has the deepest experience. Consultants’ books usually offer best practice models that characterise the stages that com
panies must pass through in order to attain supply chain excellence, but provide managers with little guidance regarding the payback to be expected from the efforts, leaving the business case shaky.
None of the books makes clear a business case for the value of SCM to the “C suite”, which describes senior executives whose job title begins with the word “chief” or “chair”. Sitting at the highest level in the organisation, these executives ultimately make the largest budgetary decisions. Hierarchically, the next level down is usually called director, and below that is a manager. “C”-level leaders have to make change happen, usually under time pressure from the stockmarket and their boards of directors. They frequently operate under circumstances of high expectations, where ambiguity or uncertainty can consume precious time and organisational goodwill. Senior management is increasingly aware of the importance of SCM, but lacks a definitive formula or roadmap for creating shareholder value from it.
Purpose of this book
The purpose of this book is to distil the essential supply chain concepts into a convenient reference for chief executives. It is designed to be clear, objective, relevant and effective (CORE) in helping executives achieve rapid results. It seeks to clarify the ambiguities surrounding the concept of SCM and its relationship to the functions from which it stems. It will be objective, not biased towards the viewpoint of logistics, manufacturing or any other traditional related function. It will concentrate on what is most relevant by eliminating and subordinating minor concepts that are not essential to getting shareholder value from SCM. The strategies outlined in the book have proved to be effective in achieving significant financial results in companies worldwide.
Clarity means no ambiguity, and to be unambiguous the content is mutually exclusive and exhaustive (MECE). Clarity also means that the key concepts can be reduced to numbers. As with so many concepts, their strength and durability can be tested by whether or not they can ultimately be quantified, because numbers do not allow for ambiguity or overlap. Whether or not a financial business case can be made for supply chain practices or technologies can be the litmus test between concepts that should be taught and implemented, and those that should fall off the bottom of the agenda.
