The document discusses the management control of projects. It defines a project as a set of activities intended to accomplish a specified end result of interest to management. Projects vary in size and complexity, from small annual audits to large multi-year efforts like landing astronauts on the moon. Effective project management requires formal control systems to manage resources, schedules, budgets, and ensure objectives are met. Key aspects of control include monitoring time, costs, quality, and generating positive goal-seeking behavior through appropriate control mechanisms. Control is exercised through various phases from initial planning to ongoing execution and post-performance reviews.
