List the best data entry method and your reason for choosing it for each of the following six situations:
a. Turnaround document for a utility company that wants notification of a change in the customer address.
b. Data retrieval allowed only if there is positive machine identification of the party requesting data.
c. Not enough trained personnel available to interpret long, written responses; many forms submitted that capture answers to multiple-choice examinations; high reliability necessary; fast turnaround not required.
d. Warehouse set up for a discount compact disc operation; bins are labeled with price information, but individual discs are not; and few skilled operators are available to enter price data.
e. Poison control center that maintains a large database of poisons and antidotes; needs a way to enter data on the poison taken; also enter weight, age, and general physical condition of the victim when a person calls the center’s toll-free number for emergency advice.
f. Online purchase of a DVD by a consumer with a credit card.
