框架

我这一阵子在研究．NET 3．0的WPF(Windows Presentation Framework)框架,去年年底学习Flex/ Apollo框架,几年前使用Windows Forms框架和ASP．NET框架。上个世纪末我专注在Java Swing框架,更早以前还使用过C++的MFC框架和OWL框架。这些都是应用框架(Application Framework)。一般来说,现在的主流应用框架都是“面向对象”加“事件驱动”的,具有类别继

Trying to adopt systems development methodologies — a case-based exploration of business users' interests

Information systems methodologies are an important component of the IS infrastructure and a primary device for organizing systems development work. Evidence suggests that methodology adoption and use are problematic. This research seeks to generate insight into business users' interest in adoption through detailed examination of a case. A framework is developed for organizing relevant research findings. The field research methods are described and details of the case reported. The case highlights the role of business managers in methodology adoption and the influence of business pressures originating in the strategic environment. Analysis shows the organizing framework to require extension to include a more direct role for business decision makers. it is argued that previous research has obscured the legitimate concern of business with systems development methodologies. As business increasingly asserts its interest in and control over IS, it will be necessary to give greater consideration to the needs of business in the selection and adoption of methodologies.

一种基于多Agent系统的企业应用集成框架

在利用Agent模板语言(APL)进行多Agent系统(MAS)快速开发的基础上,提出了基于APL和多Agent系统的面向过程的企业应用集成框架。根据业务过程的一般结构与特征,框架采用分层的业务逻辑模型,实现业务逻辑与业务执行的分离。通过这种方式避免企业业务流程的局部变化引起系统整体结构的较大变动。同时在利用APL对业务过程进行描述的过程中引入了角色与结构化活动,一方面使得用户能够根据角色把业务过程分解为子过程,另外结构化活动的引入弥补了APL在描述复杂业务流程方面的不足。通过这种方式,使得用户能够利用所提出框架,提高企业应用集成系统的开发效率,增强系统的灵活性。     

Business process design: Process comparison and integration

This paper proposes a framework for business process design, which is based on process comparison and integration. This framework supports process stakeholders to model business processes collaboratively, which can greatly enhance the efficiency and effectiveness of business process design. By applying this framework, each process stakeholder can create his or her own model of the business process. The different models of the same business process can be automatically compared to find the conflicts between them. Based on the conflicts, process stakeholders can collaborate to improve the models. Then the models can be integrated to form a more complete model.     

A requirements engineering framework for cross-organizational ERP systems

The development of cross-organizational enterprise resource planning (ERP) solutions is becoming increasingly critical to the business strategy of many networked companies. The major function of cross-organizational ERP solutions is to coordinate work in two or more organizations. However, how to align ERP application components and business requirements for coordination and cooperation is hardly known. This paper reports on the outcomes of applying a coordination theory perspective to an analysis of the ERP misalignment problem. We present a conceptual framework for analyzing coordination and cooperation requirements in inter-organizational ERP projects. The framework makes explicit the undocumented built-in assumptions for coordination and cooperation that may have significant implications for the ERP adopters and incorporates a library of existing coordination mechanisms supported by modern ERP systems. We use it to develop a proposal for how to achieve a better alignment between ERP implementations and supported business coordination processes in inter-organizational settings. We report on some early assessments of the implications of our framework for practicing requirements engineers. Both our framework and library rest on a literature survey and the first author’s experience with ERP implementation. In future empirical research, we will further validate and refine our framework.     

The procurement alignment framework construction and application

Procurement has become increasingly important for organizations acting in dynamic supply chains and competitive markets. In practice however, companies struggle with adapting and improving their procurement business function. In line with the general trend in management and organization studies, both scholars and practitioners aim to define an integrated procurement policy that is truly aligned on all organizational and IT aspects. The central aim of this paper is to present a framework that supports the definition and application of such an integrative procurement approach. The framework is developed upon insights from IT business alignment (more specifically IT Procurement alignment), procurement maturity measurement and segmentation. It facilitates organizations in monitoring the maturity and alignment of their procurement on five different business/IT perspectives. In addition, the framework enables specific procurement improvements by taking the situational aspect of procurement segmentation into account. The framework was validated twice: through interview expert consulting and through a questionnaire using scale analysis. In a case study it was found suitable for assessing procurement maturity and identifying concrete procurement improvements.
