Regardless of how you define it, information assurance is critical to the success of every company. It's a key responsibility for CIOs and IT managers, as well as everyone who stores or sends data electronically. In most cases, IT managers and CIOs shouldn't get involved in the day-to-day details of quality assurance for software programs, but they are responsible for ensuring that software quality assurance is achieved and that the data on Web sites is accurate and meets company guidelines and federal regulations before it's posted. The CIO is ultimately responsible for software QA as well as for the integrity of the data quality, ensuring that it isn't intentionally or unintentionally altered while at rest, in transmission, or through manipulation or use by a software program.
