What are the legal and ethical implications of using COTS software? Of using subcontractors? For example, who is responsible for fixing the problem when the major system fails as a result of a fault in COTS software? Wh o is liable when such a failure causes harm to the users, directly (as when the automatic brakes fail in a car) or indirectly (as when the wrong information is supplied to another system, as we saw in Exercise 1). What checks and balances are needed to ensure the quality of COTS software before it is integrated into a larger system?
