    Many companies have found out the hard way that successful e-commerce requires more than a flashy web presence. Existing business processes must be seamlessly integrated with the new, electronic form of interaction with suppliers and customers. Despite this insight, little research has focused on the transformation of doing business to achieve the presumed benefits of e-commerce. This paper gives directions on how processes may be reengineered with this aim, particularly within the service industry. The presented views are based on existing research into Business Process Reengineering best practices. Careful consideration in this paper is given to the description ofthe conceptual background, which is used to classify existing research and to position the contribution of this paper. The guidelines which are discussed are illustrated by process models, represented by UML Activity diagrams

    USING MODEL-BASED SYSTEMS ENGINEERING TO IMPROVE PROCESS MANAGEMENT IN THE DOD

    Every engineering organization within the DOD relies on documented processes, but few have access to modern process-management resources to assist in the development and the sustainment of their processes. This thesis proposes leveraging existing systems-engineering resources to offer the DOD’s engineering workforce a modern digital process-management solution. The thesis begins with a literature review of existing process-management techniques and uses this research, along with model-based systems engineering (MBSE) practices, to tailor an existing systems engineering methodology for digital process management. The MBSE process-management methodology proposed in this thesis provides the DOD engineering workforce with increased collaborative, modeling, traceability, and simulation capabilities over the traditional process-management practices in use. The effectiveness of the MBSE process-management methodology presented in this thesis was demonstrated through a case study conducted on a DOD process used to accept critical safety items for DOD use. Through the application of the MBSE process-management methodology, performance improvement goals set at the beginning of the case study by the process stakeholders were met and exceeded. Based on the results of the case study, it is the recommendation of this thesis that MBSE practices, already prevalent within the DoD engineer workforce, be utilized to improve process management within DOD engineering organizations.Civilian, Department of the NavyApproved for public release.

    Traditionally, enterprise and functional process understanding were not considered a priority in the Aerospace industry. The build of an aircraft was carried out sequentially. Now, due to increased competitive and customer pressure, time to market has been reduced. Work must be carried out concurrently to satisfy these new competitive forces. In recent years there has been a focus on Business Process Reengineering (BPR). The solution is to have a clear idea of sequence and clear toplevel process defined. Therefore it is imperative to have a clear framework to capture the process. The research demonstrates the development of a methodology to capture process within a major aircraft manufacturer. The research starts by looking at the present practices across the whole organisation. Examination of the present working practices within the organisation facilitated an objective analysis of three modelling techniques within different working groups. This fragmentation was addressed through the presentation of a generic framework. Condition of Supply processes was modelled as a demonstration to the organisations’ practitioners. Through consultation with practitioners from the working groups framework benefits were realised; • Understanding of mapping organisational processes • Generic technique for capturing working processes • Continuation of framework • Future opportunities. Conclusions highlight that the proposed framework is adaptable and easy to use, addressing user requirements; top management and operational level staff. Furthermore maps generated utilising the framework provides capability of drilling down, detailing lower level processes.MRe

    Improving enterprise business processes with systems analysis and design methodologies and tools.

    Enterprises have to be organized in a business process oriented way. This is in order to be successful in a changing and challenging business environment including uncertainty and complexity in managing business and manufacturing processes. The main objective of this thesis is to implement comprehensive modelling methodologies and tools that capture all useful information included within the enterprise business processes. This has been achieved first through implementing the Systems Analysis and Design (SAD) methodologies and tools for integrating the business design processes. The implementation should recognize the enterprise organization view, data and information view, function view, and also product/service view. Such recognition is required in order to improve the reuse of business process models for the implementation of workflow management applications. The implemented design methodologies have been demonstrated through two case studies, including the modelling of business and automotive manufacturing processes. In Addition, the Architecture of the Integrated Information System (ARIS) has been presented in both implementations using ARIS tool set. The ARIS implementation has assisted in supporting analysis for potential changes, specifying requirements, and also supporting the modeled business processes systems level design and integration activities. Results of using the selected graphical design languages with the systematic explanations of modelling the business process functions and activities revealed the need for implementing comprehensive SAD methodologies. Also, the SAD methodologies have assisted with integrating the enterprise through modelling its business activities, technology, and human elements involved. The benefits and disadvantages of each modelling methodology and tool is studied and discussed in detail in this thesis.Dept. of Industrial and Manufacturing Systems Engineering.

    The ratio between success and failure in ICT projects suggests a need for improved understanding of the ICTimplementations. New methods to evaluate the ICT projects are sought. While process modeling has been under way inorganizations for decades, this paper presents a new approach to analyzing benefits based on the introduction of ICT services.In our approach the success of ICT projects is evaluated by analyzing the productivity benefits they enable in the businessprocesses of the users. In its novel way, this paper points out the significant role of interacting processes and related actors.With the help of the Three Viewpoint Model (3VPM) and skill-matrix approaches the critical factors related to improvementbenefits can be found. Our tool allows analyzing and evaluating the output at the time even when the ICT project is notcompleted, also taking into account the dynamic nature of processes

    Building Enterprise Transition Plans Through the Development of Collapsing Design Structure Matrices

    The United States Air Force (USAF), like many other large enterprises, has evolved over time, expanded its capabilities and has developed focused, yet often redundant, operational silos, functions and information systems (IS). Recent failures in enterprise integration efforts herald a need for a new method that can account for the challenges presented by decades of increases in enterprise complexity, redundancy and Operations and Maintenance (O&M) costs. Product or system-level research has dominated the study of traditional Design Structure Matrices (DSMs) with minimal coverage on enterprise-level issues. This research proposes a new method of collapsing DSMs (C-DSMs) to illustrate and mitigate the problem of enterprise IS redundancy while developing a systems integration plan. Through the use of iterative user constraints and controls, the C-DSM method employs an algorithmic and unbiased approach that automates the creation of a systems integration plan that provides not only a roadmap for complexity reduction, but also cost estimates for milestone evaluation. Inspired by a recent large IS integration program, an example C-DSM of 100 interrelated legacy systems was created. The C-DSM method indicates that if a slow path to integration is selected then cost savings are estimated to surpass integration costs after several iterations
