Design validation, verification and review

We are an architecture firm, we make design also and execution of the same for Interior fit out.

Design review from my angle is We need to collect all the customer requirements and review the same against the drawings and issue drawings to client for their review.
Once the review comes from client and all our doubts are clear we go for
Design Verification - we need to Verify all the remarks and requirements of client, Specifications and after verification issue the Working drawings for execution
Design Validation – We check the execution with the specifications laid down by the client

Please give your remark on the above understanding.

Answer:

The purpose of the design review is to determine whether the final design is aligned with requirements of the customer or any other input requirements for the design. Customer requirements regarding the design should be reviewed prior to accepting to deliver the design and once the company a greed to deliver design according to customer requirements, those requirements become input for the design.

Design verification activities are conducted to ensure that the design and development outputs meet the input requirements. It can be done in different stages of the design project and it is an input for the design review.

Design validation is conducted to ensure that the resulting design meets the requirements for the specified application or intended use. Validation is for example, computer simulation or 3D view of the design or static calculation.

In simple terms, the validation should prove that the building wont collapse, before building has even started and verification demonstrates that the building that is already built is compliant with input requirements including customer requirements and legal requirements.
