Teaching an Ethnographic Approach to Requirements Elicitation in an Enterprise Architecture Course

Alain Wegmann, Gil Regev, Julie Lang

Requirements elicitation is an important part of information systems development. It is often performed as a technical task, but from a close look it is mainly a social activity. The main work consists of interacting with stake-holders in order to understa ...

Value Map - An Innovative Tool for Business Model Innovation

Alain Wegmann, Arash Golnam, Aarthi Gopal

In this paper, we present a modeling framework called “Value Map”. Value Map assists in conceptualization, representation and analysis of value creation and capture processes with the objective of innovating a firm’s business model. We illustrate the appli ...

Specification and Implementation of a Meta-model for Information Systems Cartography

Alain Wegmann, Gorica Tapandjieva Sekulovska

Models are used in software engineering, enterprise architecture, requirements engineering, etc. In this context, models can give support in creating a shared understanding of what exists in an enterprise. For this purpose we suggest to use a cartography t ...

Patterns for Value-Added Services Illustrated with SEAM

Alain Wegmann, Gorica Tapandjieva Sekulovska, Aarthi Gopal, Maude Laetitia Grossan

The basic idea behind the provision of a service is to hide the service implementation details from the client in such a way that more value is provided to the client. Very often support services allow too much of their implementation details to be visible ...

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 ...

Coopetition within and between value networks – a typology and a modelling framework

Alain Wegmann, Arash Golnam

This study develops a typology of coopetition in value networks, wherein a distinction is made based on two factors. Firstly, whether coopetition takes place inside a particular value network (i.e., intra-value network coopetition) or between value network ...

Coopetition-based business models: The case of Amazon.com

Alain Wegmann, Arash Golnam

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

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 ...

What We Can Learn about Business Modeling from Homeostasis

Alain Wegmann, Gil Regev

Business modeling methods most often model an organization’s value provision to its customers followed by the necessary activities and structure to deliver this value. These activities and structure are seen as infinitely malleable; they can be specified a ...

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 ...

Requirements modeling in SEAM: The example of a car crash management system

Alain Wegmann, Gil Regev, Arash Golnam, Anshuman Bahadur Saxena, Biljana Bajic-Bizumic, Gorica Tapandjieva Sekulovska, George Popescu, Maedeh Yassaee

This paper presents how business and IT requirements are captured with the Systemic Enterprise Architecture Methodology (SEAM). The method is applied to the Car Crash Management System (CMS) - Software Product Line (SPL) case study. The existing business s ...

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 ...

Simulation-Driven Approach for Business Rules Discovery

Alain Wegmann, Irina Rychkova, Biljana Bajic-Bizumic

Business rules are everywhere. Some of these rules are implicit and thus poorly enforced, others are written but not enforced, and still others are perhaps poorly written and obscurely enforced. In this work, we propose an interactive, simulation-driven ap ...

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

Alain Wegmann, Irina Rychkova, Didier Rey Marchetti, 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 Cognitive Reference Based Model for Learning Compositional Hierarchies with Whole-Composite Tags

Alain Wegmann, Anshuman Bahadur Saxena, Ashish Kishore Bindal

A compositional hierarchy is the default organization of knowledge acquired for the purpose of specifying the design requirements of a service. Existing methods for learning compositional hierarchies from natural language text, interpret composition as an ...

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

Alain Wegmann, Lam Son Lê

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 ...

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 ...

From Business Services to IT Services by Capturing Design Decisions

Claude Petitpierre, Alain Wegmann, Biljana Bajic-Bizumic

The main goals of any service-oriented design include flexible support and adaptability of business services and improved business-IT alignment. The existing approaches, however, have failed to fully meet these goals. One of the major reasons for this defi ...
