PMI Project Management Professional Practice Question

The correct answer is 'Resource scheduling expenses.' Cost of Quality (COQ) comprises prevention costs, appraisal costs, and failure costs (both internal and external). Resource scheduling expenses, while important for project management, are not part of the COQ framework.

Prevention costs aim to avoid quality issues, such as training programs or process improvements. Appraisal costs involve quality control activities like inspections and testing. Internal failure costs occur when defects are caught before product delivery, including rework or scrap. External failure costs are incurred after delivery, such as warranty claims or customer support.

By understanding these components, project managers can better balance quality investments against potential quality-related losses, leading to improved project outcomes and customer satisfaction. It's important to note that while resource management is crucial for project success, its costs are typically not included in COQ calculations.
