1. Identify why the various design reviews should take place. How might they represent an improvement over and above a single design review process at the end of the product design stage?
2. Why is the ‘voice of the customer’ so important in this process?

Assigning the procedures in this way at the outset enables quality to be ‘built in’ to the product. Processes are designed so that the right people have the right information at the right time and designs should be ‘right first time’. The review of designs is an ongoing activity, rather than one that takes place at the end of the process. This ensures that checks are made very close to the time each part of the process is carried out, and amendments are incorporated before further cost is added.
