Abstract :
The paper investigates the needs of organisational context modelling within a usability-oriented approach to interactive systems requirements engineering. Task models usually produced during the requirements engineering process are derived basically from an analysis of the the users´ individual tasks. Consequently, some major usability problems in interactive tasks performing arise from a lack of the organisational context modelling. The TOCO (task organisational context) model is proposed and then an example of context modelling using TOCO is presented
