Validation of Visual Contracts for Services

Alain Wegmann, José Diego de la Cruz Garcia

Visual modeling languages have specialized diagrams to represent behavior and concepts. This diagram specialization has drawbacks like the dif-ficulty to represent the effects of actions. We claim that visual contracts can de-scribe actions in a more compl ...

A Cognitive Reference Based Model for Learning Compositional Hierarchies with Whole-Composite Tags

Ashish Kishore Bindal, Alain Wegmann, Anshuman Bahadur Saxena

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 ...

Service-Oriented Business Design for IT students

Alain Wegmann, Blagovesta Hristova Kostova

In this Full Innovative Practice Paper, we present a teaching approach, based on service science, for integrating a business curriculum in the engineering educational program. Our approach is a composition of experiential learning, systems thinking, and se ...

From Composites to Service Systems: The Role of Emergence in Service Design

Alain Wegmann, Anshuman Bahadur Saxena

Service Design is an engineering endeavor to enrich some aspect of the real world through a man-made artifact. Systems approach to modeling reality is particularly relevant to Service Design as it seeks to explain reality as a composition of functional obs ...

A Modeling Framework for Analyzing the Viability of Service Systems

Alain Wegmann, Gil Regev, Arash Golnam

Recent research has explored the principles of service system viability based on systems inquiry invoking perspectives from Systems Theory and Cybernetics in particular Stafford Beer’s viable systems model (VSM). However based on Banathy & Jenlink (2004), ...

Revisiting Goal-Oriented Requirements Engineering with a Regulation View

Alain Wegmann, Gil Regev

Goal-Oriented Requirements Engineering (GORE) is considered to be one of the main achievements that the Requirements Engineering field has produced since its inception. Several GORE methods were designed in the last twenty years in both research and indust ...

Modeling Value Creation and Capture in Service Systems

Alain Wegmann, Arash Golnam

In service-dominant (S-D) logicvalue is viewed as being co-created between companies, customers, and other actors within a service system. In order to understand how service systems maintain their viability and competitiveness, two fundamental questions sh ...

Experiential learning approach for requirements engineering education

Alain Wegmann, Gil Regev

The use of requirements engineering (RE) in industry is hampered by a poor understanding of its practices and their benefits. Teaching RE at the university level is therefore an important endeavor. Shortly before students become engineers and enter the wor ...

A Novel Approach to Modeling Enterprise Services Leveraging Object Cloning and Multilevel Classification

Alain Wegmann

Object-oriented modeling is concerned with capturing common properties of objects. The dominant thinking in this realm is to classify objects that share certain properties into what is called a class, which in turn enables us to instantiate additional obje ...

Aligning Value and Implementation in Service Design: A Systemic Approach

Alain Wegmann, Gil Regev, Arash Golnam

The promise of service design is to enable a service supplier to prosper by delivering continuous value to customers. This prosperity is of strategic value to the service supplier. There is value in a service for both the service supplier and its service c ...

Simulation-Driven Approach for Business Rules Discovery

Alain Wegmann, 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 ...

Systemic Classification of Concern-Based Design Methods in the Context of Enterprise Architecture

Alain Wegmann, Pavel Balabko

Enterprise Architecture (EA) is a relatively new domain that is rapidly developing. The primary reason for developing EA is to support business by providing the fundamental technology and process structure for an IT strategy [TOGAF]. EA models have to mode ...

A Systemic Approach for Designing Open Innovation Value Networks

Alain Wegmann, Gil Regev, Arash Golnam

The past two decades have seen a number of changes to the business and technological environment that have favored the rise of “open” collaborative innovation as alternative to the more traditional ”closed” models. The traditional view of innovation as a c ...

Teaching Enterprise and Service-Oriented Architecture in Practice

Alain Wegmann, Gil Regev, José Diego de la Cruz Garcia

Many companies expect their IT developers to understand their business strategy and to specify IT systems that will impact favorably the execution of their business strategy. Enterprise Architecture (EA) and Service-Oriented Architecture (SOA) address thes ...

On Viable Service Systems: Developing a Modeling Framework for Analysis of Viability in Service Systems

Alain Wegmann, Gil Regev, Arash Golnam

This paper explores the contribution of systems modeling to the design and analysis of viability in service systems. We apply a modeling framework called SEAM (Systemic Enterprise Architecture Method) to gain an understanding of how a service system mainta ...

Definition of an Object-Oriented Modeling Language for Enterprise Architecture

Alain Wegmann

In enterprise architecture, the goal is to integrate business resources and IT resources in order to improve an enterprises competitiveness. In an enterprise architecture project, the development team usually constructs a model that represents the enterpri ...

Declarative Specification and Alignment Verification of Services in ITIL

Alain Wegmann, Gil Regev

IT organizations that wish to implement the best practices recommended by the IT Infrastructure Library (ITIL) need to specify the level of service provided to their customers. The implemented service needs to comply with this specification. We propose a m ...

Refinement Propagation. Towards Automated Construction of Visual Specifications

Alain Wegmann

Creation and transformation of visual specifications is driven by modeler’s design decisions. After a design decision has been made, the modeler needs to adjust the specification to maintain its correctness. The number of adjustments might make the design ...

SeamCAD: Object-Oriented Modeling Tool for Hierarchical Systems in Enterprise Architecture

Alain Wegmann

Enterprise Architecture (EA) requires modeling enterprises across multiple levels (from markets down to IT systems). Providing tool support for such models is a challenge (e.g. model containment hierarchy, navigation difficulties, problems to relate elemen ...
