This section defines how process understanding is established through structured development activities. It includes characterization of process inputs and outputs, identification of critical process parameters and critical quality attributes, and evaluation of parameter interactions.
1. Purpose and Scope Control strategy and design space establishment define how process understanding is translated into controlled manufacturing conditions that consistently ensure product quality. This article defines how: The approach aligns with expectations from FDA and principles described in…
1. Purpose and Scope Risk assessment is used to identify and prioritize process parameters and product attributes that impact product quality. It provides a structured, science-based method to distinguish between critical and non-critical elements and to justify the level of…
1. Purpose and Scope Design of Experiments (DOE) and Multivariate Analysis (MVA) are used to quantitatively evaluate process behavior, identify critical relationships, and establish statistically justified control strategies. These tools move process understanding from qualitative observation to data-driven decision-making and…
1. Purpose Process characterization and development studies define how the manufacturing process behaves across its operating range and identify sources of variability that impact product quality. The objective is to generate data that support process understanding and provide the foundation…
