generic use case diagrams in which all these
common features are represented) and make them
available for the process (through the repository)
in order to be able to use the common elements in
any activity and adapt them to our needs.
The analysis activity is composed of tasks
which build use case diagrams and specifications
to obtain the analysis model in which the require-
ments are defined. This activity produces internal
artifacts which are the output of some tasks and
the input of others. All these internal artifacts are
included in the analysis model to be used in the
following activities if this is necessary. Figure 2
shows a graphical representation of the analysis
activity tasks using SPEM 2.0 diagrams.
In this subsection, we describe the analysis
activity, enumerating and describing briefly what
tasks are parts of this activity. This analysis activ-
ity is composed of six tasks (see Figure 2):
1. Defining Use Cases of the application.
The purpose of this task is to define the
functional use cases of the application
identified from the stakeholder needs and
study the interactions with the user without
considering the specific aspects of Mobile
Grid environments.
2. Identifying secure Mobile Grid Use Cases .
In this task we study the security aspects
of the application within the Mobile Grid
context and identify the possible security use
cases and misuse cases that can be reused
from those defined in the repository, for the
system in development.
