Social Modeling for Requirements Engineering (Hardcover)

Much of the difficulty in creating information technology systems that truly meet people's needs lies in the problem of pinning down system requirements. This book offers a new approach to the requirements challenge, based on modeling and analyzing the relationships among stakeholders. Although the importance of the system-environment relationship has long been recognized in the requirements engineering field, most requirements modeling techniques express the relationship in mechanistic and behavioral terms. This book describes a modeling approach (called the i* framework) that conceives of software-based information systems as being situated in environments in which social actors relate to each other in terms of goals to be achieved, tasks to be performed, and resources to be furnished.

Social perspectives on computing have provided much insight for many years. The i* framework aims to offer a modeling approach to the relationships embedded in computer systems that is part of an engineering method that offers systematic techniques and tools providing smooth linkages to the rest of the system development process, including system design and implementation. The book includes Eric Yu's original proposal for the i* framework as well as research that applies, adapts, extends, or evaluates the social modeling concepts and approach.

許多創建真正滿足人們需求的資訊科技系統的困難在於確定系統需求的問題。本書提供了一種基於建模和分析利益相關者之間關係的需求挑戰的新方法。儘管在需求工程領域中長期以來已經認識到系統與環境之間的關係的重要性，但大多數需求建模技術以機械和行為術語表達這種關係。本書描述了一種建模方法（稱為i*框架），將基於軟體的資訊系統視為處於環境中的情境，其中社會行為者根據要實現的目標、要執行的任務和要提供的資源相互關聯。

多年來，社會計算的觀點提供了許多洞察力。 i*框架旨在提供一種建模方法，用於描述嵌入在計算機系統中的關係，該方法是工程方法的一部分，提供系統開發過程的系統設計和實施等其他部分之間的順暢鏈接的系統技術和工具。本書包括Eric Yu對i*框架的原始提案，以及應用、適應、擴展或評估社會建模概念和方法的研究。
