A socio-technical system (STS) is an approach to complex organizational work design that recognizes the interaction between people and technology in workplaces. The term also refers to the interaction between society’s complex infrastructures and human behavior. In this sense, society itself, and most of its substructures, are complex socio-technical systems. This paper addresses a class of soc...

This paper presents a Bayesian belief network (BBN) approach for socio technical system reliability assessment. A human error model (BBN) quantifies error influences arising from user knowledge, ability and task environment, combined with factors describing the complexity of user action and user interface quality. System reliability evaluation is achieved by the Scenario Reliability analyser to...

Modern software systems are characterized by ever-changing goals and requirements. Such systems operate in an environment that is dynamic, open, partly known, unpredictable. New goals arise and others are dropped, due to changes in stakeholders’ needs and priorities, government regulations, technology. Despite this dynamism, systems should meet their goals and comply with the evolving requireme...

Many people do not deliberately act to protect the data on their Smartphones. The most obvious explanation for a failure to behave securely is that the appropriate mechanisms are unusable. Does this mean usable mechanisms will automatically be adopted? Probably not! Poor usability certainly plays a role, but other factors also contribute to non-adoption of precautionary mechanisms and behaviour...

Security is often compromised by exploiting vulnerabilities in the interface between the organization and the information systems that support it. This reveals the necessity of modeling and analyzing information systems together with the organizational setting where they will operate. In this chapter we address this problem by presenting a modeling language tailored to analyze the problem of se...

Meta-design of socio-technical systems complies with the need to integrate two types of structures and processes: technical systems, which are engineered to provide anticipatable and reliable interactions between users and systems, and social systems, which are contingent in their interactions and a subject of evolution. Meta-design is focused on objectives, techniques, and processes to allow u...

Few methods address analysis of socio-technical system requirements. This paper describes a method for analysing dependencies between users/stakeholders agents and computer systems in the operational environment. Domain scenarios describing the system and its context are used to create an environment model. A method is proposed to define business organisational relationships by operationalising...

ICTs are intended to be a powerful tool in support of government transition to the “Digital Age”. The purpose of this paper is to emphasize the importance of integrating a socio-technical perspective into the body of eGovernment practices. The current realisation in Italy of an “Action plan for eGovernment” is a source of interesting preliminary evidence for our purpose. 1 Standard (Tool) Model...

Workers’ job satisfaction is considered a critical indicator for the effectiveness of socio-technical interventions in the work place. However, job satisfaction represents a complex psychological phenomenon with many contributing factors that can be difficult to assess. To facilitate assessments of job satisfaction we review psychological theories and metrics of job satisfaction to investigate ...
