Previous issue date: 2002-03-27 / This work proposes an integration of the approach CREWS L ecritoire based
on scenarios with the approach of use cases described by Regnell & al and the Method
GBRAM. In this case, the work of Regnell is extended with the notion of Requirement
Chunk (RC), strategies for discovering objectives through the relationships AND, OR, and
refinement between RCs, as well as extending the model with a physical level where the
internal actions of the system are described.
On the other side, the approach CREWS L ecritoire is extended with
coupling of objective and use case where the scenarios are obtained by applying a strategy of
refining use cases, and also with an integration of normal and exceptional scenarios in one
synthetic model of use with one unique vision for each actor.
The Method GBRAM is extended with the alternative contract dependency,
composicional contract dependency, inclusive and exclusive contract dependency, as well it
introduzed the use case technique, described by Regnell et al and extended with the notion of
scenarios for caracterize exceptionals, variationals and normal situations.
With the integration of threes methods, the new method which benefit from the
advantages of the approaches of CREWS-L ecritoire, use cases.and goals. The new method
proposes a coupling between objective and Use Cases in a top-down decomposition of
different levels of abstraction. The method combines the two concepts into a Requirement
Chunk (RC). An RC is a pair of <objective, Use Case> related with AND, OR and
refinement. These three types of relations between RCs lead to a hierarchic organisation of
RCs in three levels of abstractions: functional, behaviour, and physical. / This work proposes an integration of the approach CREWS L ecritoire based
