This workshop focuses on exploring, evaluating, and enhancing current information modeling methods and methodologies. Though the need for such studies is well recognized, there is a paucity of such research in the literature. The objective of EMMSAD'06 is to provide a forum for researchers and practitioners interested in modeling methods in systems analysis and design to meet, and exchange research ideas and results. EMMSAD'06 is the eleventh in a very successful series of EMMSAD workshops, previously held in Crete, Barcelona, Pisa, Heidelberg, Stockholm, Interlaken, Toronto, Velden, Riga and Porto.

This paper introduces a graphical modeling notation based
on coloured petri nets for the performance and cost evaluation of mobile
applications. When developing such an application some restrictions due
to the low bandwith of mobile networks need to be considered. The notation
can be used to model the workflow of an mobile application with just
a small effort. The resulting model can be (automatically) transformed
into a coloured petri net for simulating the communication behaviour
depending on typical user interactions. The simulation results are an
important basis for improving the applications performance and the occuring
costs for using mobile networks.

Business Process Management (BPM) systems provide a broad
range of facilities to enact and manage operational business processes.
Ideally, these systems should provide support for the complete BPM
life-cycle: (re)design, configuration, execution, control, and diagnosis of
processes. In the research presented, we evaluate the support provided
by the FileNet P8 BPM Suite, which is consistently ranked as one of the
leading commercial BPM systems. Taking realistic business scenarios as
starting point, we completed a full pass through the BPM cycle with
several tools from the FileNet P8 BPM Suite. We checked whether the
expected support was provided by these tools and we also tested their
interoperability. ... |

We describe the automation of a novel technique (NaLER) which was originally designed to facilitate legacy database model validation. The NaLER technique uses natural language sentences built from
live database content to elicit validation judgments from domain experts.
However, during implementation we discovered that the method we had
adopted for the automation had a serendipitous side effect in that the
legacy model first had to be mapped to an upper ontology. This normally
difficult process was significantly eased by the sentence templates which
are defined as part of the NaLER technique. It is this novel process of
mapping, and the choice of ontology it entails, which forms the focus
of the paper. ... |

Conceptual modelling methods such as Object-Role Modelling (ORM) have traditionally been developed with the aim of providing
conceptual models of databasestructures. More recently, however, such
modelling languages have shown their use for modelling(the ontology)of
domains in general.In these latter cases, the modelling effort results in a
(formally based) conceptual reasoning systems using a domain calculus
on top of a domain grammar. ...

Business practice shows that, often, different process models are employed
in the various phases of the Business Process Management life cycle,
each providing a different paradigm for capturing and representing the business
process domain. Recently, significant efforts have been made to overcome the disintegration
of process models by providing complementary language standards
for process design (BPMN) and execution (BPEL), based on the claim that these
languages are semantically integrated. However, the conceptual mapping between
both languages remains unclear, thus it is undecided whether any BPMN diagram
can be transformed to BPEL. In this paper we argue that there is conceptual mismatch
between BPMN and BPEL that needs to be identified in order to guide the
language integration process semantically. In our analysis we take into account
the various perspectives of the Business Process Management life cycle, in particular
business and technical analyst perspectives. Our approach is generic and
can also be utilized as a guiding framework for identifying conceptual mismatch
between other business process modeling languages. |

In this paper we present an approach for specifying and prioritizing information security requirements in organizations. It is important to prioritize security requirements since hundred percent security is
not achievable and the limited resources available should be directed to satisfy the most important ones. We propose to link explicitly security requirements with the organizations business vision, i.e. to provide business rationale for security requirements. The rationale is then used as a basis for comparing the importance of different security requirements. A conceptual framework is presented, where the relationships between business vision, critical impact factors and valuable assets (together with their security requirements)are shown.

In most UML-based methodologies, the analysis tasks include
mainly modeling the functional requirements using use cases, and modeling the
problem domain using a class diagram. Different methodologies prescribe different orders of carrying out these tasks, and there is no commonly agreed order
for performing them. In order to find out whether the order of these analysis activities makes any difference, and which order leads to better results, we carried
out a comparative experiment. Subjects were asked to create the two analysis
models for a certain system in two opposite orders, and the qualities of the produced models were then compared. The results of the experiment reveal that the
class diagram is of better quality when created as the first modeling task, while
no significant effect of the analysis order was found on the quality of the use
cases. We also found out that analysts prefer starting the analysis with data
modeling. |

Design by contract is a well-established paradigm in software engineering. Bertrand Meyer first introduced the rigorous distinction between the responsibilities of service provider and service consumer for fine grain software artifacts (classes). This paper considers service contracts in the context of service-oriented architecture for complex enterprise information infrastructures. Identifying dependencies between applications with service contracts may help to master the complexity of numerous interconnected informationsystems and to ease evolution towards a service-oriented architecture. ... |

Integration of new components into existing information systems (IS)
is a challenging problem mainly because of the data sharing. In this paper we
propose a situation-driven approach for IS components (IS-COTS) integration
into existing IS. We claim that such an approach has to take into account a large
number of situations and therefore has to be built by applying situational
method engineering principals and defined as a collection of reusable method
chunks. The main contribution of this work consists of the metamodel for IS-
COTS definition, the specification of the requirements for the proposed
approach and the illustration of our approach with three method chunks. |

Several different approaches to Situational Method Engineering
exist. They differ in terms of the primary element of the paradigm: the method
fragment definition. Here, we introduce four method fragment definitions from
the literature and compare their metamodels according to structural and
functional criteria. The structural comparison showed a general alignment of
some concepts that are sometimes referred with different names while the study
of the compositional aspects results in evidence of substantial differences. |
