What does batch-to-batch variability mean?

Batch-to-batch variability refers to the differences in quality, composition, or characteristics observed between different production batches of the same product. This variability can arise from factors such as changes in raw materials, production processes, or environmental conditions. It is particularly significant in industries like pharmaceuticals and food, where consistency is crucial for product safety and efficacy. Minimizing this variability is essential for ensuring reliable and uniform product performance.
