Requirements engineering has evolved historically connected to the waterfall
process model of system development. For agile processes its value continues to
be essential to develop systems that really satisfy the customer needs. The iterative
process model with high interaction with the customer is the key to preserve its
importance. Organizational and requirements patterns can be used to guide the
requirements engineer to obtain efficient processes to develop systems following
principles and approaches of agile development. In the context of a real systems
development organization a proposal of an agile process for system development
iteratively and interactively using organizational and requirements patterns has
been formulated and evaluated in a real case study. This proposal has been
modeled in the SPEM meta-model and considers advancing the application of
software metrics to the requirements phase in order to better plan following
iterations. The team that worked in the evaluation has been recruited internally in
the organization and the author of the proposal and of this dissertation has also
been a member of the organization. He trained his colleagues and followed and
recorded the evaluation conducted. A questionnaire has been formulated and
applied to the team and the results of this application are reported here. Some of
the characteristics of the proposed process have been incorporated to the
organization systems development practice and some are being considered for
incorporation with the necessary adaptation. These are here commented together
with the team opinion about the SPEM modeling and advanced application of
software metrics.
