TLDR
This paper argues that a different kind of modelling and reasoning support is needed for the early phase of requirements engineering, which aims to model and analyze stakeholder interests and how they might be addressed, or compromised, by various system-and-environment alternatives.Abstract:
Requirements are usually understood as stating what a system is supposed to do, as apposed to how it should do it. However, understanding the organizational context and rationales (the "Whys") that lead up to systems requirements can be just as important for the ongoing success of the system. Requirements modelling techniques can be used to help deal with the knowledge and reasoning needed in this earlier phase of requirements engineering. However most existing requirements techniques are intended more for the later phase of requirements engineering, which focuses on completeness, consistency, and automated verification of requirements. In contrast, the early phase aims to model and analyze stakeholder interests and how they might be addressed, or compromised, by various system-and-environment alternatives. This paper argues, therefore, that a different kind of modelling and reasoning support is needed for the early phase. An outline of the i* framework is given as an example of a step in this direction. Meeting scheduling is used as a domain example.read more

A new proposal for the integration of key performance indicators to requirements elicitation process originating from organization goals
TL;DR: In this paper, a new approach to integrate key performance indicators (KPIs) in requirements elicitation process that are derived from organization goals is proposed, which can then be used to control and reduce user requirements risk that caused by user interests.

A field study of the software design process for large systems
TL;DR: A layered behavioral model is used to analyze how three of these problems—the thin spread of application domain knowledge, fluctuating and conflicting requirements, and communication bottlenecks and breakdowns—affected software productivity and quality through their impact on cognitive, social, and organizational processes.

Goal-directed requirements acquisition
TL;DR: An approach to requirements acquisition is presented which is driven by higher-level concepts that are currently not supported by existing formal specification languages, such as goals to be achieved, agents to be assigned, alternatives to be negotiated, etc.
