Eliciting user satisfying requirements for an e-health awareness system using Kano Model

Abstract

Despite advances in the requirements elicitation research, software engineers do not still comprehend what exactly a software system/product should offer to succinctly meet the needs and expectations of users/ customers.There is a relationship between quality and user satisfaction.Eliciting user satisfying requirements contribute to the quality and competitiveness of the product.Requirements, met or unmet, can influence the extent of user/customer satisfaction or dissatisfaction for a product, because in the eyes of users/customers, products with the right functionality that satisfy them implies that such products are quality ones. This aspect of quality consideration is often neglected be researchers and practitioners. Kano Model and its extensions explore an approach that clearly explains how software product requirements/features can influence the level of satisfaction derived from such product as well as the level of dissatisfaction the absence of such requirements/feature in the product could cause in users/customers.This paper explores and applies this model in eliciting requirements for a proposed e-health awareness system.The result reveals that eliciting user satisfying requirement increases the satisfaction level of potential users/customers of the proposed product and also improves the perceived quality of such product in the eyes of the potential users/customers as evidenced from their satisfaction scores and self-stated importance ratings.
