Dashboard:
A performance measurement tool used to capture a summary of the key performance indicators (KPIs)/metrics of a company. Metrics dashboards/scorecards should be easy to read and feature “red, yellow, green” indicators to flag when metrics targets are not being met. Ideally, a dashboard/scorecard should be cross-functional in nature and include both financial and non-financial measures. In addition, scorecards should be reviewed regularly—at least on a monthly basis—and weekly for key functions—such as manufacturing and distribution—where activities are critical to the success of a company. The dashboard/scorecards philosophy can also be applied to external supply chain partners (such as suppliers) to ensure that supplier’s objectives and practices align. Synonym: Scorecard.
Data Cleansing:
The process of detecting and cleaning inaccurate, incomplete, incorrect, and irrelevant records in a data set. The records are deleted, modified or replaced as needed.
Date Code:
An identification applied to a product container or label which provides the specific date of production of the contents. Sometimes it is an actual date, but frequently it is coded for internal purposes. Date codes are often used during product recalls.
Data Communications:

Database:
Data stored in computer-readable form, usually indexed or sorted in a logical order by which users can find a particular item of data they need.
Days of Supply:
Measure of quantity of inventory-on-hand, in relation to number of days for which usage which will be covered. For example, if a component is consumed in sales or manufacturing at the rate of 100 per day, and there are 1,585 units available on-hand, this represents 15.85 days supply. The goal, in most cases, is to demonstrate efficiency through having a high turnover rate and therefore a low days’ inventory. However, realize that this ratio can be unfavorable if either too high or too low. A company must balance the cost of carrying inventory with its unit and acquisition costs, with the potential of lost business and ultimately lost customers if shortages are pervasive.
Days' Inventory:
See: Days of Supply
Days Payable Outstanding (DPO):
is an estimate of the length of time the company takes to pay its vendors after receiving inventory. If the firm receives favorable terms from suppliers, it has the net effect of providing the firm with free financing. If terms are reduced and the company is forced to pay at the time of receipt of goods, it reduces financing by the trade and increases the firm's working capital requirements. It is calculated: Days Payable Outstanding = 365 / Payables Turnover (Payables Turnover = Purchases / Payables).
Days Sales Outstanding (DSO):
also known as Collection Period (period average), is a financial indicator that shows both the age, in terms of days, of a company's accounts receivable and the average time it takes to turn the receivables into cash. It is compared to company and industry averages, as well as company selling terms (e.g., Net 30) for determination of acceptability by the company. DSO is calculated: DSO = (Total Receivables/Total Credit Sales in the Period Analyzed) x Number of Days in the Period Analyzed. Note: Only credit sales are to be used. Cash sales are excluded.

Delivery measurements are based on the date a complete order is shipped or the ship-to date of a complete order. A complete order has all items on the order delivered in the quantities requested. An order must be complete to be considered fulfilled. Multiple line items on a single order with different planned delivery dates constitute multiple orders, and multiple planned delivery dates on a single line item also constitute multiple orders.Calculation: [Total number of orders delivered in full and on time to the scheduled commit date] / [Total number of orders delivered]

The process of identifying, aggregating, and prioritizing, all sources of demand for the integrated supply chain of a product or service at the appropriate level, horizon, and interval. The sales forecast is comprised of the following concepts:1. The sales forecasting level is the focal point in the corporate hierarchy where the forecast is needed at the most generic level (i.e., corporate forecast, divisional forecast, product line forecast, SKU, and SKU by location).2. The sales forecasting time horizon generally coincides with the time frame of the plan for which it was developed (i.e., annual, 1-5 years, 1- 6 months, daily, weekly, and monthly).3. The sales forecasting time interval generally coincides with how often the plan is updated (i.e., daily, weekly, monthly, and quarterly).

Grocery Store Chain B, because of a lower sales volume, buys the same orange juice for $14.50 per case. Grocery Store Chain A and Grocery Store Chain B get together and make a deal. Grocery Store Chain A resells that product to Grocery Store Chain B for $13.50 per case. Grocery Store Chain A makes $1.00 per case and Grocery Store Chain B gets product for $1.00 less per case than it can buy from Minute Maid.
