Crafting Information Technology Governance

Information Technology (IT) governance has emerged as a fundamental business imperative, and rightfully so, because it is key to realizing IT business value. IT governance describes the distribution of IT decision-making rights and responsibilities among different stakeholders in the enterprise, and defines the procedures and mechanisms for making and monitoring strategic IT decisions. This article presents a holistic view of IT governance, in which structural, process, and relational capabilities are an integral part of an effective IT governance architecture. the article concludes with an IT Governance Assessment Process (ITGAP) model, with which business and IT executives can assess the effectiveness of their company's current IT governance architecture.     

Frameworks for Enterprise Architecture

Enterprise architecture addresses the double challenge of increasing IT efficiency while continuing business innovation. Organizations can use enterprise architecture frameworks to manage system complexity and align business and IT resources. An enterprise architecture approach can help align business and IT resources and conform them to fundamental principles and common methodologies governing the entire information systems development process. In that sense, architectural frameworks are a convenient way to support such methodologies and separate roles that facilitate and implement these methodologies as needed. Still, many organizational and technical enterprise architecture challenges remain.     

Interoperable enterprise systems: Principles, concepts, and methods

Interoperable enterprise systems (be they supply chains, extended enterprises, or any form of virtual organizations) must be designed, controlled, and appraised from a holistic and systemic point of view. Systems interoperability is a key to enterprise integration, which recommends that the IT architecture and infrastructure be aligned with business process organization and control, themselves designed according to a strategic view expressed in an enterprise architecture. The paper discusses architectures and methods to build interoperable enterprise systems, advocating a mixed service and process orientation, to support synchronous and/or asynchronous operations, both at the business level (business events, business services, business processes) and at the application level (workflow, IT and Web services, application programs).     

Components of a multi-perspective modeling method for designing and managing IT security systems

Information technology (IT) security design and management are a major concern and substantial challenge for IT management. Today’s highly complex business and technological environments and the need to effectively communicate and justify IT security requirements and controls demand methodical support. The modeling method presented in this paper addresses this demand. The method is based on the assumption that enriched enterprise models integrating technological, business, organizational and strategic aspects provide an effective foundation for developing and managing IT security systems and facilitating communication and understanding between stakeholders. The proposed modeling method for designing and managing IT security in organizations accounts for different perspectives and is based on multi-perspective enterprise modeling. The core components of the method, based on analysis of requirements at different levels of abstraction, are: modeling language concepts specifically designed to address security issues, process models that guide the use of the resulting language, and a modeling environment. The method facilitates elaborate representations of the various aspects of IT security at different levels of abstraction and covers the entire lifecycle of IT security systems. It not only supports multi-perspective requirement analysis and design but also enables monitoring and analysis of IT security at runtime. The presented artifact is evaluated with recourse to a research method that enables the configuration of multi-criteria justification procedures.     

From enterprise architecture to business models and back

In this study, we argue that important IT change processes affecting an organization’s enterprise architecture are also mirrored by a change in the organization’s business model. An analysis of the business model may establish whether the architecture change has value for the business. Therefore, in order to facilitate such analyses, we propose an approach to relate enterprise models specified in ArchiMate to business models, modeled using Osterwalder’s Business Model Canvas. Our approach is accompanied by a method that supports business model-driven migration from a baseline architecture to a target architecture and is demonstrated by means of a case study.     

面向跨企业多方协同应用的Web服务安全模型

现有的Web服务安全工具仅提供单个服务的安全策略配置功能,忽略了业务流程层面的安全需求。为此,提出一种面向跨企业多方协同应用的Web服务安全模型,将Web服务安全建模、部署与监控过程,融合到企业业务流程管理过程中。在此基础上构造基于Secure-WSCDL的建模工具、转换工具和监控工具,实现SOA架构下业务模型与安全建模在软件工程生命周期中的同步。通过简化的国际贸易进出口流程实例,验证了该模型与相应工具的有效性。
