Über dieses Buch

the virtually unlimited possibilities of modern information and communication technology. Future enterprises will therefore have to operate in an ever more dynamic and global environment. They need to be more agile, more adaptive, and more transparent. In addition, they will be held more publicly accountable for every e?ect they produce. These challenges are traditionally addressed by black-box thinking-based knowledge, i.e., knowledge concerning the function and the behavior of ent- prises, as contained in the organizational sciences. Such knowledge is su?cient, and perfectly adequate, for managing an enterprise (within the range of c- trol). However, it is de?nitely inadequate for changing an enterprise. In order to bring about changes, white-box-based knowledge is needed, i.e., knowledge concerning the construction and the operation of enterprises. Developing and applying such knowledge requires no less than a paradigm shift in our thi- ing about enterprises, since the organizational sciences are dominantly oriented toward organizational behavior, based on black-box thinking.

A Holistic Software Engineering Method for Service-Oriented Application Landscape Development

Abstract

Enterprises are transforming into enterprises which follow from a business as well as from an IT perspective a service-oriented paradigm. This change towards service-oriented enterprise and IT architectures has to be reflected in the methodologies of developing whole application landscapes as well as individual applications. Quasar (Quality Software Architecture) has been developed as the standard architecture and development method of Capgemini sd&m for individual applications. For the development of service-oriented enterprise application landscapes, Quasar Enterprise has been designed. Both Quasar and Quasar Enterprise are integrated with each other within a holistic software engineering method to seamlessly cover the full development lifecycle of service-oriented application landscapes, from business modeling and service design to actual software development. In this paper, we illustrate how a company-wide ontology of development artifacts serves as the key feature for integrating both methods.

Empowering Full Scale Straight Through Processing with BPM

Abstract

The SNS Bank (the Netherlands) has made a strategic decision to empower her customers on-line by fully automating her business processes. The ability to automate these service channels is achieved by applying Business Process Management (BPM) techniques to existing selling channels. Both the publicly available and internal processes are being revamped into full scale Straight Through Processing (STP) services. This extreme use of online STP is the trigger in a shift that is of crucial importance to cost effective banking in an ever turbulent and changing financial world. The key elements used in implementing these goals continue to be (Free) Open Source Software (FOSS), Service-oriented architecture (SOA), and BPM. In this paper we will present an industrial application describing the efforts of the SNS Bank to make the change from traditional banking services to a full scale STP and BPM driven bank.

Progressing an Organizational Approach to BPM: Integrating Experience from Industry and Research

Abstract

In 2002, Company Q knew it had a problem. No longer could it continue to run its operations as it had previously. Disparate projects were having a counteractive effect. Changing legislation and regulations were increasing reporting requirements and competition. Increased usage of its transport networks were resulting in scheduling difficulties, delays and customer dissatisfaction. A thorough review of alternative business management approaches indicated merit in adopting Business Process Management (BPM) as an organizational approach. At the time however, the process of how to adopt such an approach had received little attention in either academic or practitioner literature. Consequently, Company Q approached QUT for assistance with progressing and measuring BPM as a holistic approach to managing an organization. This paper reflects upon the role of the study in Company Q’s subsequent BPM journey.

Collaborative Enterprise Modeling

Abstract

Key challenges in enterprise business process modeling are to capture complex inter-departmental and organizational processes, and to integrate different perspectives on the operation of the enterprise. Actors often convey different and only partly overlapping perceptions of their business processes, which hinder the construction of fairly accurate models in first modeling attempts. These different accounts of the business processes need to be integrated in a way to create a realistic and acceptable picture of the enterprise. To avoid this reoccurring pitfall and trial-and-error situation, and supporting the integration of different views on enterprise processes, collaborative modeling is emerging as a powerful approach. In this chapter, we report findings from a case study in which we used a collaborative approach to support enterprise business processes modeling with participation of analysts, process owners, and professionals. The deliverables of this chapter are based on a case study with participation of industry partners during a collaborative enterprise modeling session. We will reflect on the approaches used, lessons learned and the role of technology for supporting collaborative modeling.

Assessing the Efficiency of the Enterprise Architecture Function

Abstract

Many large organizations have difficulties managing enterprise transformations involving their extensive and complex portfolio of business processes, information systems, and infrastructure. Enterprise Architecture (EA) is an increasingly important instrument to better manage enterprise transformations. EA provides a means for getting insight into the current state landscape, creating a target blueprint, and setting out a roadmap to achieve that target state. Although investing heavily in EA, few organizations have implemented a truly efficient EA function. In order to implement an improvement cycle for the EA function, organizations conduct efficiency assessments. In this article we present an integral assessment model to determine the efficiency of the entire EA function. Our model takes an eclectic view, which makes it easily adaptable to organization specific characteristics. We use a case description to illustrate the working of our model, and to show which type of concrete insights it provides to identify points for improvement.

Business Value of Solution Architecture

Abstract

The theory and especially the practice of IT architecture have been developed quite vigorously the last years. However, hardly any quantitative data about the value of IT architecture is available. This paper presents the results of a study, which measures the value of IT solution architecture for software development projects. The study identifies ten architecture-related project-variables and correlates these with eight project success variables. Statistical analysis of 49 IT projects shows that the use of solution architecture is correlated with decreased budget and time overrun, increased reliability of project planning and increased customer satisfaction. The results of the study indicate that IT usage of solution architecture for custom software development projects leads to better project results. Also the limitations of the study are discussed.

Quality Enhancement in Creating Enterprise Architecture: Relevance of Academic Models in Practice

Abstract

This chapter presents an explicit approach, that is both theory and practice driven, to support evaluation and collaboration activities when creating enterprise architecture. The approach will be applicable in addressing evaluation and collaboration related aspects in two primary phases of the Architecture Development Method (ADM) of The Open Group Architecture Framework (TOGAF). The phases of interest are preliminary phase (defining architecture principles) and phase A (creating architecture vision). These two phases involve activities where evaluation of alternatives and collaboration among key stakeholders and enterprise architects, are paramount. Based on theoretical insights, a collaboration process to facilitate the steps in the formulated approach has been developed. Both the approach and the process design for its realisation, have been evaluated by exposing them to practitioners. This was done using structured walkthoughs. Insights from these walkthrough sessions with experienced enterprise architects, were used to enrich the theoretical models. Generally this chapter aims at demonstrating how theoretical models, enriched with experiences from industry, can fill the currently existing lack of profound analysis of success factors for enterprise architecting. Note that this lack exists in both academia and industry.

Architecture-Driven Requirements Engineering

Abstract

This paper presents an architecture driven requirements engineering method. We will demonstrate how to integrate requirements engineering in architecture design and we will demonstrate how to use enterprise architectures during solution realization projects. We will demonstrate how architecture can be used during problem investigation, solution specification and solution validation through an example application.

Informed Governance of Enterprise Transformations

Abstract

Modern day enterprises are confronted with a variety of challenges, forcing them to continuously transform themselves to better meet these challenges. The diversity of the challenges and the resulting desires to transform (parts of) the enterprise, make it desirable to align all required and desired transformations in such a way that they complement each other rather than nullifying, or even undermining, each other’s effects. Therefore, mature governance of these enterprise transformations is absolutely crucial. We will argue that this requires a transformation authority, being the organisational function which is responsible for the governance of enterprise transformations. In this chapter, our driving interest is the implementation of mature transformation authorities.

Judging whether a portfolio of enterprise transformations is well aligned requires insight into the desired overall result, as well as the planned and achieved effects of the individual transformations. This is what we refer to as informed governance. In this chapter we will position the discipline of enterprise architecture (referring to the architecture of the enterprise, and not just enterprise-wide IT architecture) as the core means to achieve informed governance. We will argue that mature governance of enterprises transformations presupposes the use of enterprise architecture to direct the portfolio of transformations.

Our discussions we will be based on theories from management science, as well as experiences from our own industrial practices. We will also discuss two cases of enterprises involved in the implementation of transformation authorities and use these to further refine our theoretical model.

Strategy and Architecture – Reconciling Worldviews

Abstract

The relationship between strategy and enterprise architecture is troublesome in many organizations. It seems that this cumbersome relationship is similar to the more ‘traditional’ tension that seemingly exists between business and IT. This paper explores three underlying causes of this tension, most notably (1) overlap in domain of expertise, (2) different languages and (3) different underlying worldviews. It is argued that there is no single solution to resolving this tension. Instead, the tension should be seen as a polarity that must be managed continuously. Only by ensuring that both groups of practitioners have a shared understanding of the issues that the firm faces and are committed to resolving them together can the tension between these groups be relieved.

Measuring the Risks of Outsourcing: Experiences from Industry

Abstract

In this paper we present the findings of 50 cases regarding the application of the Rightshore Assessment Study (RAS), a tool and approach for determining the sourcing scenario based on the measurement of the risks of outsourcing. RAS is aimed at assessing both the organizational capability and the complexity of the IT domain, yielding the potential qualitative and quantitative benefits and risks for outsourcing information systems portfolios or part thereof. After a description of RAS, we present an overview of the findings of the studies of the past few years. These studies have been conducted at 10 different organizations in various industry sectors. We have related aspects such as process maturity, people, knowledge management, IT platforms and support to the benefits and risks of outsourcing. In this paper, we compare these findings, analyze them and draw conclusions on both the outsourcing risk factors and ways how to improve them. We conclude with a chapter with an analysis of the approach and ideas for further research.
