Hi,

A design review is a milestone within the product development process whereby a design is evaluated against its requirements in order to verify the outcomes of the previous activity and identify the issue and correct it . There are different ways to conduct a design review 1. physical test 2.examination (walk-through).The ultimate design review, if successful, therefore triggers the product launch or product release.
Design review ensures that
1.The proposed design will meet the requirements.
2.The design can be implemented in the required time.
3.The design will be consistent with technical goals of the organization.
