Scenario-Based Requirement Analysis
نویسنده
چکیده
A method for scenario based requirements engineering is described. The method uses two types of scenario, structure models of the system context and scripts of system usage. A modelling language is reported for describing scenarios, and heuristics are given to cross check dependencies between scenario models and the requirements specification. Heuristics are grouped into several analytic treatments that investigate correspondences between users’ goals and system functions; input events and system processes to deal with them; system output and its destination in the scenario model, and acceptability analysis of system output for different stakeholders. The method is illustrated with a case study taken from the London Ambulance Service report. The prospects for scenario based RE and related work are discussed.

Detection of deep and hidden mineralization using the surface geochemical data is a challenging subject in the mineral exploration. In this work, a novel scenario based on the spectrum–area fractal analysis (SAFA) and the principal component analysis (PCA) has been applied to distinguish and delineate the blind and deep Mo anomaly in the Dalli Cu–Au porphyry mineralization area. The Dalli miner...

Introduction Climate change conditions have been deteriorated in recent years due to increasing emissions of greenhouse gases, whose negative effects on human societies are one of the major concerns in 21st century, leading to introduction of several scenarios for predicting the climate parameters affected by increasing emissions of greenhouse gases. Therefore, this study sought to investigate...
