Abstract:
Whether a software, app, service or infrastructure is trustworthy represents a key success factor for its use and adoption by organizations and end-users. The notion of trustworthiness, though, is actually subject to individual interpretation, e.g. organizations require confidence about how their business critical data is handled whereas end-users may be more concerned about the usability. These concerns manifest as trustworthiness requirements towards modern apps and services. Understanding which Software Quality Attributes (SQA) foster trustworthiness thus becomes an increasingly important piece of knowledge for successful software development. To this end, this paper provides a first attempt to identify SQA, which contribute to trustworthiness. Based on a survey of the literature, we provide a structured overview on SQA and their contribution to trustworthiness. We also identify potential gaps with respect to attributes whose relationship to trustworthiness is understudied such as
e.g. accessibility, level of service, etc. Further, we observe that most of the literature studies trustworthiness from a security perspective while there exist limited contributions in studying the social aspects of trustworthiness in computing. We expect this work to contribute to a better understanding of which attributes and characteristics of a software system should be considered to build trustworthy systems.
