We propose a dynamic way to model task structures from multi viewpoints at different abstraction levels. For this, we provide a multi-view task modeling framework that defines a two-layered approach: at conceptual-level specific framework concepts for providing a conceptual foundation to model and structure tasks at different abstraction levels; and at representation-level through a formal task modeling language. The motivation behind this is decoupling the complexity of the underlying system behavior and business logic, and giving a comprehensive picture from all perspectives. The framework concepts and the language are customizable and extendible, thus enabling the framework to be used for creating task models for different purposes, from system analysis to performing usability evaluation. We provide details of a case study in which we successfully used the framework for conducting task model-based usability evaluation.
