Due: 8 April 1996

1. For three programs determine as accurately as possible (a) the age of the program and (b) the number of people who have been involved in writing and modifying it. Each program must be more than two years old, must have had three or more people involved, and you must not have been involved in writing or modifying the program. State how you determined your answers.

2. In one page or less of text, argue why developing and maintaining shrinkwrap software (such as that produced by Microsoft, Adobe, etc.) is different from developing and maintaining ``contract'' software (such as that produced by Boeing, EDS, etc.).
