Historically, package integrity testing relied heavily on probabilistic methods such as dye ingress or microbial immersion challenges. While these methods provide valuable pass/fail data under specific conditions, they are subject to sample size limitations and do not guarantee detection of all critical leaks. Probabilistic methods require the simultaneous occurrence of multiple conditions (e.g., presence of liquid, pressure differential, organism size, growth conditions) to yield a positive result.

This section emphasizes that package integrity should not be an afterthought but an integral part of the product development process and throughout a product's entire lifecycle. It aligns with modern quality-by-design (QbD) principles, where quality is built into the product and process from the earliest stages. pda technical report 27 pdf
