This textbook covers business architecture modeling in all its essential aspects. Based on the MMABP Philosophical Framework for Business System Modelling it provides a comprehensive overview of four basic dimensions of the business system model together with their essential relationships. The methods, techniques, and tools are described and explained for every model type with examples. Special attention is paid to integrating all dimensions using the Business System Consistency Framework.The book is divided into six chapters. Chapter 1 introduces business architecture and the approaches and tools to model it. MMABP is introduced with its basic principles and put in context with other approaches to business architecture modeling. Chapter 2 then deals with the modeling of a business system in terms of its objectives. The basic principles of process modeling, the distinction between global and detailed views of processes, and an approach to managing the detail of the process model in the form of four levels of process abstraction are introduced. Chapter 3 describes the modeling of a business system in terms of its underlying concepts and the business rules that apply within the modeled system. The basic principles of object modeling, the distinction between global and detailed views of objects, and the approach to capturing the object life cycles are introduced. Chapter 4 presents a simplified metamodel that describes how all models of the business system are related, and consistency rules that guide the analysts to avoid possible inconsistencies. Chapter 5 focuses on the implementation of the business system in an organization. It describes the role and specifics of its information system, explains the comprehensive procedure for building the process-driven organization, and reflects on the organizational maturity and its role in the further development of a process-driven organization. Eventually, Chapter 6 presents a complex example of the application of MMABP, including the functioning prototype of the process system. The prototype is then used to illustrate an essential difference between the conceptual and technology levels of models, and the importance of distinguishing between them.This textbook is written for students in enterprise architecture or business information systems as well as for professionals developing enterprise information systems or process-driven organizations.

This book is about the information modeling of organizations in the widest sense possible. This term express the general meaning of the term "organizational modeling" with the light flavor of informatics practices rather than just the IS or IT view of the organization. Although the topic of the cognition of organizational structure and behavior traditionally belongs to the management theory; informatics brings to this area the necessary exactness in the shape of formal specifications and a systemic style of thinking. Informatics is a source of sophisticated techniques and tools, aimed on discovering the general regularities of the organizational structure and behavior (often called "business rules") with the ability to abstract all non-contentual aspects of the organizational system. Information technology, on the other hand, is a key enabler of organizational changes as it is established in all literature mentioning the theory of business reengineering. Consequently, the well designed Information System must be a clear picture of all substantial aspects of the organization (both the structural and the behavioral ones). Information modeling aims to create the view of the organization which is, on the one hand independent of any non-contentual aspect (including the information technology at first); on the other it is fully consistent with following the process of the development of the Information System (i.e., the infrastructure in general).The book introduces the methodology for modeling the business system based on two complementary views which covers both ontology and business process model of the organization using standard languages UML and BPMN and including tools for ensuring the consistency of both models. The book also outlines the original methodology for service-oriented building of the process managed organization and discusses the problem of the process-oriented management in the field of public administration.
