Abstract-The research paper aims to identify the most important characteristics of Representational State Transfer (REST) that affect the quality and quality requirements of web services. A systematic literature review was conducted to identify the most frequently mentioned REST characteristics, which were then verified by industry experts in Sri Lanka. Based on the verified variables, a survey questionnaire was developed using a conceptual model. The survey was distributed to 33 developers and 34 consumers of RESTful web services, and their responses were analysed using Partial Least Square Structural Equation Modeling (PLS-SEM) in SmartPLS3 Version 3.1.6 to determine the linkages between REST characteristics and Quality of Service (QoS). Importance-Performance Matrix Analysis was executed to identify the REST characteristics with higher importance and performance towards QoS. Based on the findings, a framework was developed with REST characteristics that could improve QoS in the early development stages of RESTful web services. This framework is useful for service providers and developers to develop and implement high-quality RESTful web services that meet the QoS requirements of their customers.
