How many operational variables are listed?

How many operational variables are listed?

• A. Seven
• B. Five
• C. Six
• D. Eight

Answer: (A)

Operational variables are the factors in the operation that you can measure and control during the process. To answer how many are listed, go through the items in the list and count only those that describe actual variables you can monitor and adjust. Skip items that are descriptions of the procedure, constraints, or goals, and don’t double-count the same variable if it’s mentioned in multiple ways. When you apply this approach to the list, you end up with seven distinct operational variables. That’s why seven is the correct count. If you’re unsure, write down each item and check whether you can measure and influence it during operation; only those that pass that check count toward the total.
