Establishing requirements that must be met in order for a product to be deemed suitable for its intended use is one of the key components of developing drugs and drug products. Specifications are defined as "a list of tests, references to analytical techniques, and acceptable acceptance criteria, which include numerical limits, ranges, or other criteria for the tests stated" by the International Conference on Harmonization (ICH). This is a crucial quality standard where the makers put out and defend the requirements that serve as the foundation for the regulatory bodies' approval.

The requirements are specifically outlined throughout the product design phase, outlining the goals the final product is intended to accomplish utilising particular parts, packaging, closures, raw materials, and completed goods.
Regulations organisations like CGMP ( 211.160 and 211.165) require laboratory testing to make sure the product complies with the specifications. It guarantees that all of the components and other factors described above fulfil the specifications criterion in addition to ensuring that the product performs as needed.

Out-of-Specification, ...
... or OOS, is the term used when the results of the laboratory test reveal that the product values are outside the specifications or acceptance standards. Based on a root cause analysis, additional steps must be made to prevent its FDA rejection or receipt of a warning letter.
