Practical experiences show that requirements are always incomplete and inconsistent because software systems are complex that developers can hardly fully capture during the system development. User requirements are often expressed in general and qualitative terms, which are imprecise in nature and usually conflicting with each other. Therefore, how to elicit, specify, and satisfy requirements, including functional and nonfunctional requirements, is always a major concern in engineering software. In recent years, goal-driven approaches have attracted an increasing attention in the area of requirements engineering, as goal information is valuable in identifying, organizing, and justifying software requirements. The tenet of goal-driven approaches is to provide the motivation and rationale to justify software requirements, especially on why systems are constructed. Benefits of focusing on the notion of goals in the requirements engineering process include (1) helping acquire requirements by elaborating what requirements are required to support the goals, (2) making easy the justification of the presence of requirements in a progressive manner by starting from system-level and organizational objectives from which such lower level descriptions can be progressively derived, and (3) providing the information for detecting and resolving conflicts that arise from multiple viewpoints among stakeholders. In this special issue, we are featuring six articles devoted to the state-of-the-art in modeling, assembly, deployment, and management of goal-driven requirements engineering related methods, tools, and technologies. Chiung-Hon Leon Lee and Alan Liu propose a new framework for extracting and satisfying service requests in the context of service-oriented applications. In particular, the goal model of a service is built by the service developers by analyzing the use case requirements documents to extract both the functional (goal) and nonfunctional properties of the service. This model is then used as the background
