Design change

A design change is the modification conducted to the product. It can happen at any stage in the product development process.[1][2]

The design changes that happen early in the design process are less expensive when compared to those that take place after it is introduced into full-scale production. The cost of the change increases with its development time.[3] Fundamentally, the design changes can be classified into pre production and post production design changes. The pre-production changes can happen in the conceptual design stage, prototype stage, detailing stage, testing stage. The post -production stage change will happen almost immediately the product is introduced into the production.[4] This might be due to several reasons such as market response, design faults uncovering, design mistakes, not meeting customer requirements, so on and so forth.[5] One of the tools to minimize this type of design change is House of Quality.[6]
