A Situated Approach to Systems Based Modeling of Services

Alain Wegmann, Anshuman Bahadur Saxena

Situatedness refers to the imagery that a conceptualization invokes. The image, as a whole, provides the context for interpreting the relevance of the categories revealed in the image. At a basic level of conceptualization, the conceptual relevance of an o ...

A Method of Functional Alignment Verification in Hierarchical Enterprise Models

Alain Wegmann

Enterprise modeling involves multiple domains of expertise: requirements engineering, business process modeling, IT development etc. Our experience has shown that hierarchical enterprise models, made of an assembly of system models, are effective. In these ...

An RM-ODP Based Ontology and a CAD Tool for Modeling Hierarchical Systems in Enterprise Architecture

Alain Wegmann

Enterprise Architecture (EA) requires modeling enterprises across multiple levels (from markets down to IT systems) i.e. modeling hierarchical systems. Our goal is to build a Computer Aided Design (CAD) tool for EA. To be able to build this CAD tool, we ne ...

Towards the Definition, Implementation and Communication of an IT Strategy: The Case of IT Strategy at EPFL

Didier Rey Marchetti, Alain Wegmann, Gorica Tapandjieva Sekulovska

Large enterprises need to coordinate the IT initiatives that exist in different organisational units of the enterprise. If these initiatives are not coordinated, the resulting IT system is likely to become difficult to use and expensive to develop/maintain ...

A Return on Our Experience of Modeling a Service-oriented Organization in a Service Cartography

Alain Wegmann, Gorica Tapandjieva Sekulovska

We present a longitudinal project using action design research, which is a four-year collaboration between two EPFL entities: The research Laboratory for Systemic Modeling (LAMS) and EPFL’s IT department, called the VPSI. During that time the VPSI was goin ...

Ontology for SEAM Service Models

Alain Wegmann, Gorica Tapandjieva Sekulovska

A service system is a popular concept in academia and industry. At the same time, it is a challenging concept to represent, due to its recursive nature and difficulty to relate it to entities in reality. In this paper we present an ontology for modeling se ...

Modeling an Emergency Service System for a Hospital Network

Alain Wegmann, Gil Regev

In this paper we describe a service modeling project done at an IT department that provides IT services to a network of state owned healthcare providers in the state of Vaud in Switzerland. The goal of the project is to un- derstand how to maintain busines ...

High-level design and analysis of business processes the advantages of declarative specifications

Alain Wegmann, Gil Regev

Business process modeling techniques, such as BPMN, encourage the early specification of the exact order in which the activities of the process will be executed. However, a business process may be exposed to different environments and subjected to many con ...

The Role of Invariants in the Co-evolution of Business and Technical Service Specification of an Enterprise

Alain Wegmann

We explore invariants as a linking mechanism between the business and technical service perspectives: From the business perspec- tive, invariants can be used to model (business) requirements of an en- terprise; from the technical perspective, invariants ex ...

Coopetition In The Global Book Industry: The Case Of Amazon.Com’s Evolution

Alain Wegmann, Arash Golnam

Coopetition (collaboration between competing firms) is a phenomenon which has recently captured a great deal of attention due to its increasing relevance to business practice. The current research on coopetition is still short in explaining how the potenti ...

Extending Business Process Models with Appreciation

Alain Wegmann, Gil Regev

We use homeostasis, the maintenance of steady states in an organism, to explain some of the decisions made by participants in a business process. We use Vickers’ Appreciative System to model the homeostatic states with Harel’s statecharts. We take the exam ...

Where do Goals Come From: the Underlying Principles of Goal-Oriented Requirements Engineering

Alain Wegmann, Gil Regev

Goal is a widely used concept in requirements engineering methods. Several kinds of goals, such as achievement, maintenance and soft goals, have been defined in these methods. These methods also define heuristics for the identification of organizational go ...

On the Situated Semantics of Service Systems

Alain Wegmann, Anshuman Bahadur Saxena

Service System refers to the group of entities that work together to implement a service. An important challenge for the service designer is to organize her conceptualization of the service in a way that helps her identify the functional components require ...

A Method and Tool for Business-IT Alignment in Enterprise Architecture

Alain Wegmann, Gil Regev, Pavel Balabko

Enterprise architects seek to align enterprise processes and structure with their supporting IT systems so that enterprises can flourish in their environment. The enterprise architecture (EA) discipline has emerged from business best practices. EA framewor ...

Problem structuring to enable innovation in business/IT projects

Tatiana Porté, Alain Wegmann, Gil Regev

In this paper, we present a problem structuring method in business and IT analysis illustrated with an example. The project describes an IT consulting case done for a Swiss medical society faced with a problem of change management and digital transformatio ...

Hierarchy-oriented modeling of enterprise architecture using reference-model of open distributed processing

Alain Wegmann

Modeling Enterprise Architecture (EA) requires the representation of multiple views for an enterprise. This could be done by a team of stakeholders that essentially have different backgrounds. One way to do this is to structure the model into hierarchical ...

A Situated and Embodied Approach to Service Design

Alain Wegmann, Anshuman Bahadur Saxena

The two basic questions that every service-designer has to consider are – what features to include in a service, and who all to engage in the implementation of these features? We demonstrate that the true semantics of the value, which a service aims to cre ...

Modeling Service-Level Requirements: a Constancy Perspective

Alain Wegmann, Gil Regev

IT service requirements offer a seemingly classic Requirements Engineering (RE) problem. But, when attempting to solve it with RE methods, we are faced with difficulties. RE methods encourage us to identify the functional and non-functional requirements of ...

Value Map: A Diagnostic Framework to Improve Value Creation and Capture in Service Systems

Alain Wegmann, Arash Golnam

In this paper, we introduce a problem structuring method (PSM) called “Value Map”. Value Map is an extension to the Supplier Adopter Relationship Diagram in the Systemic Enterprise Architecture Method (SEAM). Value Map assists in understanding, analysis an ...

Capturing Design Rationale with Functional Decomposition of Roles in Business Processes Modeling

Alain Wegmann, Pavel Balabko

Enterprises need to create and maintain the fit between their business processes and their business process support (BPS) systems. This frequently requires re-engineering of business processes. If the business processes design ration-ales are made explicit ...
