COSTUME: A
Method for Building Quality Models for Composite
COTS-based Software Systems
The
use of quality models during the selection of Commercial, Off-The-Shelf
(COTS)
products provides a framework for the description of the domains which
the COTS
products belong to. Descriptions of COTS products and user quality
requirements
may be translated into the quality concepts defined in the model,
making
selection more efficient and reliable. In this paper we propose a
method for
the construction of quality models for Composite COTS-based Software
Systems
(CCSS), defined as systems that are composed by several interconnected
COTS
products. Selection processes carried out when procuring a CCSS require
not a
single COTS product to be selected but a set of them. As a consequence,
instead
of a classical quality model, we need a more elaborated one, defined as
the
composition of those models that belong to the domains of the COTS
products
that form the CCSS.
