In e-business, addressing the technical issues alone is not enough to drive the evolution of existing legacy applications, but it is necessary to consider problems concerning the strict relationship that exists between the evolution of the legacy system and the evolution of the e-business process. To fulfill this purpose, this chapter proposes a strategy for extracting the requirements for a legacy system evolution from the requirements of the e-business process evolution. The strategy includes a toolkit composed of a set of decision tables and a measurement framework, both referring to the organization, business processes, and legacy software systems. The decision tables allow the identification of the processes to be evolved, the actions to be performed on them and their activities, and the strategies to be adopted for evolving the information systems. The measurement framework aims at achieving a greater understanding of the processes and related problems, taking into account organizational and technological issues.

Printing service order information systems sometimes experience problems in completing running business processes including, frequent loss and inaccuracy in registering orders from customers, often also losing order data from customers, recording orders often experience errors, resulting inaccurate reporting of order data. A computerized ordering service information system will greatly help improve performance and accuracy in making reports on business processes running at a company. The existence of enterprise modeling of information systems ordering printing services with the TOGAF framework will be a method that greatly helps management make a decision that will synergize with the business process activities at the company. So that the objectives of the system can be achieved properly. The TOGAF framework can be a solution and will help to produce a system architecture design, a business process architecture, a technology architecture, a number of proposed business opportunity strategy proposals and an ongoing system change proposal.

It is generally accepted that the process control of a small and medium-sized manufacturing business enterprise is the foundation of high quality care of firm’s business processes. Any business process is seen as an indivisible sequence of activity steps designed to perform complex business activities. In its statutory documents the company should have concise descriptions of at least the main processes, along with their contexts in a given department of the company and the employee position.The main business processes, of course many others, are not immutable, on the contrary, they are very often changing. Many processes occur, others are modified others disappear as antiquated and useless to support strategic business objectives. All this is a consequence of the firms’ effort needed to maintain competitiveness in the harsh and dynamic consumer market.Business processes are not isolated, many of them are part of a relatively large process chains, so-called enterprise services, see (Erl, 2005). The discipline of Software Engineering responded to the possibility of consolidating enterprise functionality with enterprise services with the method SOA (Service Oriented Architecture) leading to new applications for enterprise information systems.In contrast to business processes, business services are still not sufficiently recognized in the statutory documents of enterprises. Informaticians, producing software applications for enterprise information systems, must draw on company management knowledge relating to the general context and processes together with management to prepare business services. There are therefore more relevant questions based on the emergence of corporate services and information modeling in the discipline of Information Engineering. Acceptable responses are not included in a lot of publications or in publications of the doyen of SOA Thomas Erl, see (Erl, 2006) and thus the proposed SOA paradigm suffers from the same problem.The present article tries to give an answer to those questions and show the relevant theoretical basis for finding service solutions of business process logic. Furthermore, this article wants to show possible conversions of known methods of process analysis of Information Engineering disciplines, such as the method Eriksson – Penker Business Extensions, or the method ARIS by prof. Scheer, into the platform of enterprise services.

Modelling Approaches

Purpose - The purpose of this paper is to present a business process measurement framework for the evaluation of a corpus of business processes modelled in different business process modelling approaches. The results of the application of the proposed measurement framework will serve as a basis for choosing business process modelling approaches. Design/methodology/approach - The approach uses ideas of the Goal Question Metric (GQM) framework to define metrics for measuring a business process where the metrics answer the questions to achieve the goal. The Weighted Sum Method (WSM) is used to aggregate the measure of attributes of a business process to derive an aggregate measure, and business process modelling approaches are compared based on the evaluation of business process models created in different business process modelling approaches using the aggregate measure. Findings - The proposed measurement framework was applied to a corpus of business process models in different business process modelling approaches and is showed that insight is gained into the effect of business process modelling approach on the maintainability of a business process model. From the results, business process modelling approaches which imbibed the principle of separation of concerns of models, make use of reference or base model for a family of business process variants and promote the reuse of model elements performed highest when their models are evaluated with the proposed measurement framework. The results showed that the applications of the proposed framework proved to be useful for the selection of business process modelling approaches. Originality - The novelty of this work is in the application of WSM to integrate metric of business process models and the evaluation of a corpus of business process models created in different business process modelling approaches using the aggregate measure.

The traceability links existing between a business process and the supporting software systems s is a critical concern for the organizations, as it directly affects their performance. Methodologies and tools are needed for detecting these kinds of relationships and keeping an evidence of the existing connections. This paper proposes an approach for modelling a business processes evidencing the links existing between their activities and the components of the supporting software systems. The approach described in this paper is concerned with the use of information retrieval techniques to software maintenance and, in particular, to the problem of recovering traceability links between the business process models and the components of the supporting software system. An information retrieval approach is introduced based on two processing phases including syntactic and semantic analysis. The application of the approach is explored through a case study.

Adequate Communication

A long-standing and important goal in the field of e-business is to achieve interoperability between interacting commercial, private, and public partners as well as to support it by adequate communication and Information Systems. For the design and realization of such interoperable systems, many instruments, methods, and technologies were developed in the past, such as standards and ontologies for the exchange of data and knowledge. Most of them focus on the technical issues of interoperability. But in practice, e-business refers to interactions between self-determined, goal-driven social-technical systems. Thus, further aspects like business goals, organizations, business processes, and social relationships have to be modeled and discussed. Therefore, a more holistic understanding of interoperability is attempted in this chapter. Based on this extended perception of interoperability in e-business this chapter will consider and discuss not only well known facets of interoperability, but also additional often neglected facets of interoperability, and try to systematize them with the aid of the concept of morphology.

Development Processes

The constant change and rising complexity of organizations, mainly due to the transforming nature of their business processes, has driven the increase of interest in business process management by organizations. It is recognized that knowing business processes can help to ensure that the software under development will meet the business needs. Some of software development processes (like unified process) already refer to business process modeling as a first effort in the software development process. A business process model usually is created under the supervision, clarification, approval, and validation of the business stakeholders. Thus, a business process model is a proper representation of the reality (as is or to be), having lots of useful information that can be used in the development of the software system that will support the business. The chapter uses the information existing in business process models to derive software models specially focused in generating a data model.

Business Analysis

Although numerous firms have experimented with business process reengineering (BPR), many have achieved less than dramatic results (Davenport, 1993; Hammer & Champy, 1993; Kotter, 1995). To explore possible reasons for BPR underachievement, an in-depth case study was undertaken. The case focuses on events surrounding the redesign of a fundamental business process (Personal Lines Insurance) at Safeco Corporation. Redesign is led by the Information Systems and Services (ISS) department as they are in charge of the Personal Lines Systems (PLS) that support the business. Analysis of the interviews provides a detailed description of the project and uncovers possible reasons for failure of the reengineering effort.
