True or False: A master file should only contain information on past events if they were successful.

A master file is designed to serve as a comprehensive record of all relevant information regarding events, regardless of their outcomes. This file typically includes details about both successful and unsuccessful events, as documenting a full range of experiences provides valuable insights for future planning and decision-making.

Including information on past events—whether they succeeded or not—enables organizations to analyze trends, understand audience preferences, and identify areas for improvement. By excluding unsuccessful events, the organization would lack critical data that could guide them in bettering future events or addressing issues that led to less favorable outcomes. Hence, the statement that a master file should only contain information on past events if they were successful is incorrect. The inclusion of all pertinent data is necessary for comprehensive analysis and planning.
