Introduction to the Exploring Modeling Methods for Systems Analysis and Design '07 workshop

Erik Proper, Terry Halpin
The field of information systems analysis and design includes numerous modeling methods and notations (e.g. ER, ORM, UML, DFDs, BPMN, EPC), that are typically evolving. Even with some attempts to standardize, new modeling methods are constantly being introduced, many of which differ only marginally from existing approaches. These ongoing changes significantly impact the way information systems are being analyzed and designed in practice.

Towards a Quality-Aware Web Engineering Process

Cristina Cachero, Geert Poels, Coral Calero, vrijdag 22 juni 2007

Evidence-Based Web Engineering (WE) is necessary in order to (1) help industry practitioners in making rational decisions about technology adoption and (2) increase the acceptability of WE methodologies. Particularly, empirical data should be provided to support traditional WE claims such as increased productivity or better quality of the applications deployed using a WE methodology.

Towards a life cycle of method engineering

Naveen Prakash, S.B. Goyal, vrijdag 22 juni 2007

We propose a three stage method development life cycle. The requirements engineering phase consists of elicitation and representation of method intentions, the design phase produces the architechture of the method and the construction phase consists of organizing method features in a coherent whole.

Representation of Method Fragments: A Domain Engineering Approach

Iris Reinhartz-Berger, Anat Aharoni, vrijdag 22 juni 2007

The discipline of situational method engineering (SME) promotes the idea of retrieving, adapting, and tailoring fragments, rather than complete methodologies, to specific situations. In order to succeed in creating good methodologies that best suit given situations, fragment representation and cataloguing are very important activities. We introduce a visual SME approach,whose roots are in domain engineering.

Towards a Pragmatic Perspective on Requirements for Conceptual Modeling Methods

Boris Wyssusek, Johannes Maria Zaha, vrijdag 22 juni 2007

The mere unmanageable amount of techniques for conceptual modeling of information systems poses a challenge both for users of existing techniques and for developers of new techniques. However, interpreting the emergence of new conceptual modeling techniques as a result of changing architectural paradigms for information systems seems to be inappropriate.

An Ontological Framework of Method Engineering: An Overall Structure

Mauri Leppänen, vrijdag 22 juni 2007

A large number of strategies, approaches, meta models, techniques and procedures have been suggested to support method engineering (ME). Most of these artifacts, here called the ME artifacts, have been constructed, in an inductive manner, synthesizing ME practice and existing ISD methods without any theory-driven conceptual foundation. Also those ME artifacts which have some conceptual groundwork have been anchored on foundations that only partly cover ME.

Improving Data Modelling Through the use of Case-Based-Reasoning

Paulo Tomé, Ernesto Costa, and Luís Amaral, vrijdag 22 juni 2007

Experience plays an important role in Information Systems data modelling activity. This role is justified by the fact that determining the correct and consistent information requirements is a difficult and a challenging task. Currently three types of data modelling techniques are widely used: entity-attribute-relationship, object-relationship and object-oriented.

Extending the ORM conceptual schema design procedure with the capturing of the domain ontology

Peter Bollen, vrijdag 22 juni 2007

In this paper we will extend the ORM conceptual modeling language with constructs for capturing the relevant parts of an application ontology in a list of concept definitions. In addidtion we give the adapted ORM meta maodel and an adaptation of the accompanying Conceptual Schema Design procedure (CSDP) to cater for the explicit modeling of the relevant parts of an application- or domain ontology in a list of concept definitions.

Integrating Requirement and Solution Modelling: Approach and Experiences

Anders Carstensen, Lennart Holmberg, Per Högberg, Svein G. Johnsen, Dag Karlsen, Frank Lillehagen, vrijdag 22 juni 2007

We discuss how an Enterprise Modelling approach, namely C3S3P, has been applied in an automotive supplier company. The paper concentrates on the phases of the C3S3P development process such as Concept Study, Scaffolding, Scoping, and Requirements Modelling. We have also presented the concept of task pattern which has been used in the MAPPER project for capturing, documenting and sharing best practices concerning business processes in organisation.

Can UML Be Simplified?

John Erickson, Keng Siau,vrijdag 22 juni 2007 

UML’s complexity is regularly criticized by practitioners and researchers alike, who argue that such complexity is a considerable detriment to the adoption and use of UML in the field. Attempts have been made to assess and/or measure UML’s complexity in a number of ways.

Ten Years Plus with EKD: Reflections from Using an Enterprise Modeling Method in Practice

Janis Stirna, Anne Persson, vrijdag 22 juni 2007

This paper presents experiences and reflections from using the EKD Enterprise Modeling method since the beginning of the 1990’ies. A large number of application cases have been carried out. The paper focuses on the EKD modeling language, the EKD modeling process and supporting tools.

Extending the Discussion of Model Quality: Why Clarity and Completeness may not always be enough

Jan Mendling, Jan Recker,vrijdag 22 juni 2007 

Quality of modeling for information systems analysis and design is an important field of research in which, however, a comprehensive and generally acknowledged understanding is still outstanding. Notions of “model” and “quality” often remain vague and focus on particular aspects such as “syntax” or “semantics” rather than a comprehensive perspective on model quality.

QoMo: A Modelling Process Quality Framework based on SEQUAL

Patrick van Bommel, Stijn Hoppenbrouwers, vrijdag 22 juni 2007

This paper aims to contribute to the area of conceptual model quality assessment and improvement. We present a preliminary modelling processoriented ‘Quality of Modelling’ framework (QoMo), mainly based on the established SEQUAL framework for quality of models.

Subtyping Revisited

Terry Halpin, vrijdag 22 juni 2007

In information systems modeling, the business domain being mod-eled often exhibits subtyping aspects that can prove challenging to implement in either relational databases or object-oriented code. In practice, some of these aspects are often handled incorrectly.

Fact Oriented Business Service Modeling

Peter Bollen, vrijdag 22 juni 2007

In this paper we will present the results of research into factoriented business service modeling. The set of modeling constructs that are defined in this paper are fully ‘compatible’ with the models in the dataoriented perspective in the fact oriented school of conceptual modeling.

A UML Profile for Modeling Framework-based Web Information Systems

Vítor Estêvão Silva Souza, Ricardo de Almeida Falbo, Giancarlo Guizzardi, vrijdag 22 juni 2007

The rapid evolution of the area of Web Engineering has motivated the proposal of several methods and frameworks for the development of Web Information Systems (WISs). In particular, it is becoming more and more common to use containerbased architectures and frameworks when it comes to their development.

Automatic Knowledge Retrieval from Conceptual Models

Jörg Becker, Daniel Pfeiffer, vrijdag 22 juni 2007

Conceptual models are an important repository for knowledge in companies and public institutions. The retrieval of this knowledge can prepare reorganisations projects and support IT investment decisions. However, so farthis information source has hardly been utilized in automated analyses. We argue that if modelling languages are endowed with specific characteristics the resulting models can be analysed in an automatic manner.

Exploring the Dynamic Costs of Process-aware Information Systems through Simulation

Bela Mutschler, Manfred Reichert, vrijdag 22 juni 2007

Introducing process-aware information systems (PAIS) in enterprises (e.g., workflow management systems, case handling systems) is associated with high costs. Though cost evaluation has received considerable attention in software engineering for many years, it is difficult to apply existing evaluation approaches to PAIS.

Modelling MAS-Specific Security Features

G. Beydoun, G. Low, H. Mouratidis, B. Henderson-Sellers, vrijdag 22 juni 2007

In this paper, we pursue a modelling approach to address security requirements for multi-agent systems (MAS). This will allow developers to account for both the system and agent-specific security requirements of a MAS during the requirements phase and throughout the whole Software Development Lifecycle of the system.

Defense against Insider Threat: a Framework for Gathering Goal-based Requirements

Virginia N. L. Franqueira, Pascal van Eck, vrijdag 22 juni 2007

Insider threat is becoming comparable to outsider threat in frequency of security events. This is a worrying situation, since insider attacks have a high probability of success because insiders have authorized access and legitimate privileges. Despite their importance, insider threats are still not properly addressed by organizations.
