Collapse Button Quick Abstract
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 service systems with the SEAM systemic method. As part of the ontology, we provide a meta-model, well-formedness rules and formalization in the Alloy language. The ontology we propose represents an updated and minimalistic version of the existing SEAM modeling language ontology that puts an emphasis on the behavior. We validated the ontology by modeling around 20 case studies. The running example we use throughout this paper is one of these case studies.

Collapse Button Quick Abstract
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 exclusively propositional form of part-whole relations. Nevertheless, the lexico-syntactic patterns used to identify the occurrence of part-whole relations fail to decode the experientially grounded information, which is very often embedded in various acts of natural language expression, e.g. construction and delivery. The basic idea is to take a situated view of conceptualization and model composition as the cognitive act of invoking one category to refer to another. Mutually interdependent set of categories are considered conceptually inseparable and assigned an independent level of abstraction in the hierarchy. Presence of such levels in the compositional hierarchy highlight the need to model these categories as a unified-whole wherein they can only be characterized in the context of the behavior of the set as a whole. We adopt an object-oriented representation approach that models categories as entities and relations as cognitive references inferred from syntactic dependencies. The resulting digraph is then analyzed for cyclic references, which are resolved by introducing an additional level of abstraction for each cycle.

Collapse Button Quick Abstract
Business-IT alignment is complicated because of the need to align multiple business and IT points of view. A philosophical foundation can help generate methods that bring together these disparate viewpoints in a common model that all stakeholders can agree to. In this paper, we describe the philosophical foundations of the Systemic Enterprise Architecture Method (SEAM) and show how it can help business-IT alignment with the example of a concrete business process. These foundations are applicable to other methods as well.

Collapse Button Quick Abstract
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 and design of value creation and capture in service systems. To develop the Value Map, we reviewed the literature that examine value creation and capture particularly in the marketing and microeconomics domains. The literature review helped us to discover and explore the relationships among the important concepts relevant to the processes of value creation and capture. Having identified these concepts and their relationships, we graphically represented them in the form of a conceptual model. The conceptual model provided insights into the structure and the dynamics of value creation and capture and served as a reference point for developing the notational elements and the modeling constructs in the Value Map. We illustrate the applicability of the Value Map by modeling value creation and capture in the service system of a social networking company called Webdoc.

Collapse Button Quick Abstract
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 deficiency is the gap that exists between how the computer science and management science communities perceive the concept of service. We present a flexible, semi-automatic, model-driven approach to designing IT services that directly satisfy business needs and requirements. We begin with the design of business services and the capture of the design decisions that transform the business design through multiple model layers to the IT service design. All layers can be simulated using the Alloy Analyzer tool. The last layer can be run on a given target platform. This approach is demonstrated on the running example based on the consulting project conducted at the company General Ressort. The central aspect of our approach is separating the design decisions from anything that can be automated. It provides the multi-perspective view of the system, by making the modeling process faster, leaving the designer the space to focus on the design decisions and not on drawing the models.

Collapse Button Quick Abstract
Business modelling methods most often model an organization’s value provision to its customers followed by the activities and structure necessary to deliver this value. These activities and structure are seen as infinitely malleable; they can be specified and engineered at will. This is hardly in line with what even laymen can observe of organizations, that they are not easy to change and that their behaviour often is not directly centred on providing value to customers. We propose an alternative view in which organizations exist by maintaining stable states that correspond to their identity. We analyse how these states are maintained through homeostasis, the maintenance of ones identity. Homeostasis helps to explain both the inability of organizations to provide maximum value to their customers and their reluctance to change. From this point of view, resistance to change is not something to fight or to ignore but an essential force behind organizational behaviour that can be built upon for creating adequate strategies.

Collapse Button Quick Abstract
Many firms redesign their business models to be service-oriented in light of the increasingly central role that services play in their business models. Two fundamental questions should be addressed in designing service-oriented business models: how is value created for and with the customers by the service provider? and, how is the value captured by the service provider?. The first question deals with “value creation” while the second addresses “value capture” in the “service value equation”. A service-oriented business model that addresses these two questions can sustain the viability and competitiveness of the firm as a service provider. The extant research mainly focuses on the service design from the value creation perspective. Thereby, there has been little discussion about service providers’ value capture and its trade off with value created for and with service customers. In this paper, adapting a holistic perspective, we introduce a modeling framework that can assist in understanding, analysis and design of value (i.e. value creation and capture and their interplay) in service-oriented business models. Our modeling framework is grounded in insights and conceptualizations of the extant theories, constructs and frameworks on value creation and capture in business and service systems. We illustrate the applicability of our framework by conducting a descriptive case study of the value creation and capture in Amazon service system in the period between 1997 and 2001.

REGULATION, THE INVISIBLE PART OF THE GOAL ORIENTED REQUIREMENTS ENGINEERING ICEBERG

Collapse Button Quick Abstract
Goal-Oriented Requirements Engineering (GORE) is considered to be one of the main achievements that the requirements of the Requirements Engineering field has produced since its inception. Several GORE methods were designed in the last twenty years in both research and industry. Curiously, GORE methods seem to have emerged out of nowhere in the early 1990s, the concept of Goal appearing as a natural element in explaining human and organizational behaviour. We have found no theoretical or philosophical work that explicitly link GORE to an underlying organizational model. In this paper, we show that most GORE methods are implicitly based on the goal-seeking, decision making organizational model. We argue that there are other organizational models that may better explain human behaviour, albeit at the expense of more complex models. We present one such alternative model that explains individual and organizational survival through continuous regulation. We give our point of view of the changes needed in GORE methods to support this alternative view through the use of maintenance goals and beliefs.

Collapse Button Quick Abstract
SEAM is an enterprise architecture method that defines a visual language for modeling. Our goal is to provide formal semantics for SEAM. Model simulation, model comparison, and refinement verification are practical benefits we expect from this formalization. This paper complements the existing SEAM semantics by formalizing property relations. This formalization is based on the theory of multi-relations and Relation Partition Algebra (RPA).

Collapse Button Quick Abstract
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 process tedious for large specifications. We are interested in techniques that will reduce the modeler’s obligation to control specification correctness. Every single transformation of the visual specification can be captured by the notion of refinement used in formal methods. In this work we present the technique that supports a stepwise refinement of visual specifications based on calculations. We use refinement calculus as a logic for reasoning about refinement correctness. When a design decision is made by the modeler, the necessary adjustments are calculated based on rules of refinement propagation. Refinement propagation can automate the specification adjustment and enforce its correctness.
