Introduction
The purpose of this report is to provide an example of a
CommonKads design model [Van de Velde et al., 1993]. Although it not
evaluates the values and qualities of the design model itself, it can
sure be helpful in the discussion about what should be in a design
model and where and how should it be represented.
To achieve this goal we investigated a scheduling task in the crew
scheduling department of Sabena. Previous analysis of this task was
already done in [Duursma, 1993]. For reasons of clarity we included
a brief summary of the task and communication model that were
developed in the latter paper. Elaborating this task analysis resulted
in the construction an expertise model and finally the required design
model.
