Abstract: | AbstractOperations management tends to be treated independent of other business functions—the silo syndrome. In this article, we call for operations management (OM) to broaden its perspective by strengthening linkages with other functions of the business, thereby to realize competitive advantages and strategic integration, as well as to avoid resource misallocation. The issues involved are presented and tested by examining the effects of intermeshing sales, general and administrative (SG&A) expenditures with customer-centred flow manufacturing, the latter being measured by system inventory as surrogate for customer lead time. In doing so, we designate trends in total inventory as the independent variable—representative of a dominant target of flow/lean management—and trends in SG&A expenditures as the output variable. The research tasks are enabled by inventory and SG&A data being widely available in companies’ audited financial statements. Such hard data offers methodological and validation advantages over, say, opinion-based survey research. The research adds bulk to existing flow/lean management theory and can be helpful in inducing primary business functions (e.g. OM, finance, sales and marketing) and sub-functions (such as SG&A and management accounting) to engage in cross-functional efforts in the cause of flow-oriented process improvement and company competitiveness. |
