Supporting Requirements Reuse in a User-centric Design Framework through Task Modeling and Critical Parameters
MetadataShow full item record
Better establishing requirements will benefit design. By adapting task-modeling techniques to support critical parameters within the requirements-analysis phase of scenario-based design, we are able to provide designers with a systematic technique for capturing requirements in a reusable form that enables and encourages knowledge transfer early in the development process. The research work presented concentrates on the domain of notification systems, as previous research efforts led to the identification of three critical parameters.
Contributions of this work include establishment of a structured process for capturing critical-parameter requirements within a user-centric design framework and introduction of knowledge reuse at the requirements phase. On one hand, adapting task models to capture requirements bridges the gap between scenarios and critical parameters, which benefits design from user involvement and accurate requirements. On the other hand, using task models as a reusable component leverages requirements reuse which benefits design by increasing quality while reducing development costs and time-to-market.
