When rewriting the ticket-issuing system description using a structured approach, in which field would you describe the condition under which the ticket is issued (e.g., credit transaction validated and personal identifier correct)?
Correct Answer
Pre-condition
Explanation
The pre-condition specifies what must be true before the function (ticket issuance) can be called. The condition 'credit transaction has been validated and personal identifier is correct' is a pre-condition for the ticket issuance action to proceed.
