Requirements Elicitation for a Blockchain Vaccine Supply Chain Management Web/Mobile Application

Abstract

Background: This paper presents the processes carried out to be able to develop/gather the complete and right requirements to developing a secure and effective blockchain system for the vaccine supply chain. The paper hence presents the requirements elicitation activity of the Blockchain web/mobile application for vaccine supply chain. Methods: A mixed-methods methodology was applied. The methods employed were; document review, survey, focus group workshops, interviews, observation, brainstorming, brainwriting Unified Modeling Language and system dynamics. Results: The paper present results of each of the methods used in requirements elicitation for eight themes, namely: temperature monitoring; quality, suitability and capacity of transport facilities; information systems and supportive management functions; storage quality, suitability and capacity; maintenance of cold-chain equipment; vaccine distribution; vaccine management policies and stock management. The results presented gave understanding of the operation of the existing vaccine supply chain and the requirements for the blockchain web/mobile application for vaccine supply chain. Conclusions: The requirements for the development of the desired vaccine supply chain web/mobile application were captured and documented.
