Sažetak

A new necessity-based method for the elicitation and classification of requirements in the early phases of the product design process is presented. The purpose is to guide a design engineer through the process of requirement elicitation so as to compile a more appropriate requirement list and avoid under- and over-constraining a product.
The new method is based on the extended Form, Fit and Function approach. Its steps are derived from an in-depth analysis of literature sources. The applicability of the method is shown on a case study on residential solar panels. The method is validated by a case study on an air ventilation register box and by expert opinion.
The necessity-based method fills the gap in the well-established methods for requirement elicitation and classification. It gives an insight into which requirements are important for certain product. The elicitation part of the new method reminds a design engineer of important case-related requirements. The classification part helps establishing rules on mandatory requirements.
