HRM 3400 Lecture 22 Notes – Data Collection
Introduction
• In other cases, data collection is automated via special input devices such as scanners,
point-of-sale devices, and terminals.
• Data collection begins with a transaction (e.g., taking a customer order) and results in
data that serves as input to the TPS.
• Data should be captured at its source and recorded accurately in a timely fashion, with
minimal manual effort, and in an electronic or digital form that can be directly entered
into the computer.
• This approach is called source data automation.
• An example of source data automation is an automated device at a retail store that
speeds the checkout process—either UPC codes read by a scanner or RFID signals picked
up when the items approach the checkout stand.
• Using both UPC bar codes and RFID tags is quicker and more accurate than having a
clerk enter codes manually at the cash register.
• The product ID for each item is determined automatically, and its price retrieved from
the item database.
• The point-of-sale TPS uses the prie data to deterie the ustoer’s ill.
• The store’s ivetory ad purhase dataases reord the uer of uits of a ite
purchased, the date, the time, and the price.
• The inventory database generates a management report notifying the store manager to
reorder items that have fallen below the reorder quantity.
• The detailed purchases database can be used by the store or sold to marketing research
firms or manufacturers for detailed sales analysis.
• Many grocery stores combine point-of-sale scanners and coupon printers.
• The systems are programmed so that each time a specific product—for example, a box
of cereal—crosses a checkout scanner, an appropriate coupon—perhaps a milk
coupon—is printed.
