Definition
The ability of a process to produce successive batches with comparable properties and quality under equivalent process conditions.
Human Explanation
Successive batches should achieve a comparable and acceptable level of quality.
Why it Matters
Reproducibility provides important evidence that the process remains stable and controlled.
Conceptual Boundary
It does not mean that every result is identical; expected variation may remain acceptable within defined requirements.
Practical Perspective
Evaluation should use results from multiple successive batches and examine trends, variation and relevant process conditions.
