What is a specification mismatch in data processing?

A specification mismatch in data processing refers to a situation where the data types involved are not compatible with the expected processing requirements. This can occur when, for example, a system expects a numeric value but receives a string representation of a number, which causes errors in calculations or data manipulations. Such mismatches can lead to failed operations, unexpected behaviors, or inaccuracies in the results of data processing tasks. Ensuring compatibility in data types is crucial for seamless processing and to maintain the integrity of the data workflows. Recognizing and addressing specification mismatches is an essential part of data validation and quality assurance processes.
