One way to think of the differences among validation, verification and monitoring is to use the following questions that are linked to basic grammar: • Monitoring: Are the operations being done as intended?
The method will return a boolean value indicating whether the validation succeeded or not.
HACCP has mandated the validation of CCPs since the introduction of the seven principles in 1989.
Stier Validation has always been part of the Hazard Analysis and Critical Control Point (HACCP) system, but it is an even greater issue in today’s food safety management systems.
According to the Capability Maturity Model (CMM) we can also define validation as The process of evaluating software during or at the end of the development process to determine whether it satisfies specified requirements. A product can pass while verification, as it is done on the paper and no running or functional application is required.
But, when same points which were verified on the paper is actually developed then the running application or product can fail while validation.
