  This report describes de design of an experiment that intends to compare two
variants of a modeldriven system development method, so as to assess the impact
of requirements engineering practice in the quality of the conceptual models.
The conceptual modelling method being assessed is the OO-Method [Pastor and
Molina 2007]. One of its variants includes Communication Analysis, a
communication-oriented requirements engineering method [Espa\~na, Gonz\'alez et
al. 2009] and a set of guidelines to derive conceptual models from requirements
models [Espa\~na, Ruiz et al. 2011; Gonz\'alez, Espa\~na et al. 2011]. The
other variant is an ad-hoc, text-based requirements practice similar to the one
that is applied in industrial projects by OO-Method practitioners. The goal of
the research, summarised according to the Goal/Question/Metric template [Basili
and Rombach 1988], is to:
  *) analyse the resulting models of two model-based information systems
analysis method variants; namely, the OO-Method (OOM) and the integration of
Communication Analysis and the OO-Method (CA+OOM),
  *) for the purpose of carrying out a comparative evaluation
  *) with respect to performance of the subject and acceptance of the method;
  *) from the viewpoint of the information systems researcher
  *) in the context of bachelor students.
