Abstract
Establishing appropriate requirements is essential in early phases of product design for obtaining enough information and in order not to over-constrain the product. Consequences of failing to do so are discussed. An overview of state-of-the-art methodologies for eliciting and classifying requirements is presented. Existing elicitation methods tend not to focus on the requirements content and the classification methods overlook the missing requirements. To overcome this gap a new method for requirements elicitation and classification is proposed. It defines the universally necessary requirements, product-specific necessary requirements and optional requirements. The appropriateness of the method is verified with a case-study on air ventilation register box and expert opinions. The positive contribution of the method is confirmed through evaluation with novice design engineers.
