Introduction
The importance of efficient working capital management (WCM) is indisputable. Working capital is the difference between resources in cash or readily convertible into cash (Current Assets) and organizational commitments for which cash will soon be required (Current Liabilities). The objective of working capital management is to maintain the optimum balance of each of the working capital components. Business viability relies on the ability to effectively manage receivables, inventory, and payables. Firms are able to reduce financing costs and/or increase the funds available for expansion by minimizing the amount of funds tied up in current assets. Much managerial effort is expended in bringing non-optimal levels of current assets and liabilities back toward optimal levels. An optimal level would be one in which a balance is achieved between risk and efficiency.
A recent example of business attempting to maximize working capital management is the recurrent attention being given to the application of Six Sigma® methodology. Six Sigma® methodologies help companies measure and ensure quality in all areas of the enterprise. When used to identify and rectify discrepancies, inefficiencies and erroneous transactions in the financial supply chain, Six Sigma® reduces Days Sales Outstanding (DSO), accelerates the payment cycle, improves customer satisfaction and reduces the necessary amount and cost of working capital needs. There appear to be many success stories, including Jennifer Towne’s (2002) report of a 15 percent decrease in days that sales are outstanding, resulting in an increased cash flow of approximately $2 million at Thibodaux Regional Medical Center. Furthermore, bad debts declined from $3.4 million to $600,000. However, Waxer’s (2003) study of multiple firms employing Six Sigma®
