Abstract iStar is a general-purpose goal-based modelling language used to model
requirements at early and late phases of software development. It has been used in …

Requirements elicitation research is reviewed using a framework categorising the
relativeknowness' of requirements specification and Common Ground discourse theory. The …

In goal-oriented requirements engineering, goal models have been advocated to express
stakeholder objectives and to capture and choose among system requirement candidates. A …

Change is an essential characteristic of software development, as software systems must
respond to evolving requirements, platforms, and other environmental pressures. In this …

The purpose of this paper is to present an alternative systems thinking–based perspective
and approach to the requirements elicitation process in complex situations. Three broad …

Abstract [Context/Motivation] Different modeling techniques have been used to model
requirements and decision-making of self-adaptive systems (SASs). Specifically, goal …

There are many types of dependencies between software requirements, such as the
contributions dependencies (Make, Some+, Help, Break, Some-, Hurt) and business …

Modern software systems operate within the context of larger socio-technical systems,
wherein they interact—by exchanging data and outsourcing tasks—with other technical …

Self-adaptive systems (SASs) are increasingly leveraging autonomy in their decision-
making to manage uncertainty in their operating environments. A key problem with SASs is …

This research compares the impacts of change requests due to requirement defects on the
outcomes of software development projects developed using the Waterfall methodology …
