In the modelling and simulation community, validation determines the degree of accuracy of associated data to the real world according to the model; verification determines whether a computer model and the associated content represent the developer’s conceptual descriptions and specifications. We check whether the developed product is right. Validation relates to the user either the product is accepted by user or not while verification relates to the design and specifications of software.
