According to the Ito report announced by the Ministry of Economy, Trade and Industry in August 2014, it was pointed out that the issues of Japanese companies are not in asset turnover rates and financial leverage, but in terms of their ability to make earnings, compared to western companies. However, I believe that both accounts receivable turnover and inventory turnover are generally lower than those in Europe and the United States, among asset turnover rates, which is an issue for CCC (Cash Conversion Cycle) management.<br /><br />Inventory is an important management resource.<br />Inventory is said to be a source of profit for business, at the same time, to cause loss. Especially in manufacturing, retail and wholesale business, management indicators are used to measure whether product inventory is being converted into sales efficiently.<br />In general, the following two are used.<br />1. Inventory turnover rate<br />Inventory turnover (times) = sales &middot; cost of sales (annual) &divide; inventory amount<br />The inventory turnover rate is mainly used by executives for presentations for investors or shareholders.<br />2. Inventory turnover period<br />Inventory turnover period = inventory amount &divide; sales or cost of sales (monthly or daily)<br />In fast-rotating industries such as foods, the daily sales are used for denominator and &quot;days of stock days&quot; is indicated.<br />The inventory rotation period is practically used well.<br /><br />Annual average and month end stock are used for inventory, but the actual value for sales period / cost of sales is used for that period.<br />It is enough to explain the past and current situation of inventory, but I think that it is inappropriate as an indicator for future decision-making internally. In other words, it is not inventory turnover as management accounting.<br /><br />I am convinced that inventory turnover days are an indicator that can assist decision-making to be shared by management, sales department in charge of operations, manufacturing, procurement, and logistics personnel as inventory-based management consultant.<br /><br />Table of contents<br /><br />Chapter 1 &nbsp;<br />Now, why inventory turnover is paying attention? <br />(1) Inventory is a scorecard of the corporation<br />(2) Management efficiency<br />(3) Weekly operation cycle<br />(4) Management indicators related to inventory turnover<br />Chapter 2 &nbsp;<br />Management Accounting and Financial Accounting<br />Chapter 3 &nbsp;<br />CCC positioning and comparison between Japan and the United States, International comparison<br />(1) Key financial indicators<br />(2) Positioning of CCC<br />(3) CCC comparison between Japan and US<br />(4) Sporting goods industry<br />(5) Six major chemical companies in Japan<br />(6) Electronic components Industry in Japan<br />(7) Electronic components Trading companies in Japan<br />(8) MRO (Maintenance Repair and Operations) in Japan<br />(9) International comparison by industry<br />Chapter 4 &nbsp;<br />Importance of information sharing on weekly performance results between management and operations sites<br />(1) Month-end closing and next month-end payment <br />(2) Monthly accounting system<br />(3) Accounts Receivable<br />(4) The case of Nidec Motor<br />(5) The case of HP<br />(6) Japanese companies pursuing Inventory freshness / time-axis management<br />(7) Japanese companies pursuing weekly operation<br />(8) Lehman shock (2008) through 2012 (after 311 Earthquake and Thai Flood)<br />Chapter 5 &nbsp;<br />Management Methods, Promotion Structure and Required Systems and its usage<br />(1) Cash cycle and lead time<br />(2) Stock out rate<br />(3) Channel inventory turns<br /><br />Chapter 6 &nbsp;<br />Practices: Inventory Dollar Control and Unit Control<br /><br />&nbsp;
