4.2b 4.2b(1) Accurate, timely, and reliable data are important to Collin’s information system. Whether data are collected manually, by machine, by voice, or by LAN, data need to be reliable and properly identified within the system to ensure that the best decisions are made. To ensure data integrity, Collin always provides the input with a source and date so that the originator can be contacted to clarify any suspect information. When possible, automatic checks ensure that manually entered data are within preset limits such as number of characters or anticipated range of values.
