Consider the following independent situations:

(i)A computer programmer addeda module to the payroll program that started with an IFstatement to identify his employee number. If it were his record, the program was instructed to multiply computed pay by 1.5, thus increasing the programmers pay by 50%.

(ii)A manufacturing company required all its hourly workers to sign in by passing their personal identification cards across an automated time clock that captured the data and transmitted it to the computer for subsequent processing. An employee who worked the first shift arranged with her brother, who worked the second shift, to use her card to sign out when he completed his work shift. The employee thus generated pay for 16 hours per day, one-half at overtime rates. The employee and her brother split the additional pay.

(iii)A disgruntled programmer often came to theoffice in the evenings to copy confidential client data, such as customer lists and discounts, onto a storage device, which he sold to competitors at handsome prices.
