Resumen:
This article discusses a case study in which they used two complementary methodologies: MDA (Model Driven
Architecture) and MERODE (Model-driven, Existence-dependency Relation Object-Oriented Development). MDA
as MERODE are methodologies that support the paradigm of the separation of domain model (conceptual model,
business model) of the application of their technical specifications in order to generate flexible solutions, and
therefore easier to maintain. As has already been shown in previous studies the benefits that these methodologies
bring to the attributes of flexibility and maintainability of the applications, our work focused on verifying the
impact on development time involved in using these two methods together. To achieve our goal, was conducted
using the estimated time COCOMO (Constructive Cost Model), during the actual measurements were taken, and
finally analyzed the differences between estimated and actual times, with the result that the use of MDA and
MERODE together does not affect significantly the development time of the application.
