Based on the pattern selected the pattern
builder expands the BSP pattern. It uses as input
parameters: the pattern selected; the organizational
unit and; the kind of work item. As output
parameter it presents the complete pattern
(expansion) of BSP with transactions (Figure 8).

4 CONCLUSIONS AND FUTURE
WORKS
The organization of work, both within and between
companies, is becoming more and more complex.
This is why information systems have been
developed to support the management of process
and their automation (Aalst, 2002). Workflow
systems associated to other technologies (e.g.:
internet, electronic documents management and
database systems) make such automation feasible.
One of the most important stages in the
development of a workflow system is modeling of
BP executed in the organization. In this paper we
observed that the existents models for WP design
do not have enough support for the structural
aspects of the organization. This constraint may
commit the accuracy and efficiency of the
Workflow Project.
Aiming at approaching this constraint, we
proposed the TMBP an extension of TMWP to
support the structural aspects of the organization
and the reuse of BSP patterns.
The paper has shown that the patterns stored in
the Pattern Catalogue are selected by a Catalogue
manager and expanded by a BSP builder.
Future works could preview the development of a
wizard to support BSP modeling, based on the
semantics of the PCatalogue package. For example,
the FORO-WF (Foro, 2002) tool, based on the WIDE
model could be modified to support TMWP extension.
Last, but not least, new extensions to the TMBP may
come to be necessary, as new patterns are identified.
Patterns that would need other modeling elements for
their expansion in a BP model, besides those proposed
in the TMBP. This flexibility of TMBP if
fundamental, once as mentions in (Aalst, 2002), there
are many kinds of BPs performed in organizations,
which may be related to different structural aspects.
