How does planning for prevention costs assist in meeting stakeholder needs and expectations, while still providing required performance and reliability?

Prevention costs are proactive investments made to avert poor quality in products, services, or processes. Planning for these costs involves activities such as proper training, process documentation, and using appropriate equipment. By investing in these areas, the project team builds quality into the deliverables from the outset. This approach directly helps in meeting stakeholder needs for performance and reliability by minimizing the occurrence of defects and failures, rather than reacting to them after they happen. This aligns with the principle that it is less costly to prevent defects than to correct them.

The guide defines prevention costs as those incurred to "Build a quality product," including costs for training, documenting processes, and equipment. This is in contrast to appraisal costs (assessing quality) and failure costs (rework).

2. Kerzner, H. (2017). Project Management: A Systems Approach to Planning, Scheduling, and Controlling (12th ed.). Wiley. In Chapter 23, "Quality Management," Kerzner explains the cost of quality, defining prevention costs as those associated with preventing poor quality, such as quality planning and training, which directly supports the idea of avoiding failures.

This academic review reinforces the classic quality cost model, stating, "Prevention costs are incurred to prevent or avoid failure problems" (p. 650). This aligns with the chosen answer that these costs are used to avoid poor quality. https://doi.org/10.1108/02656710610672470
