Abstract: With the market shift from a seller to the buyers market, in a highly competitive environment, companies look forward to new management. Business process reengineering (Business Process Reengineering, BPR) is the result of many business practices. Can improve business operations performance breakthrough new management ideas and methods. This article describes the technology-based workflow process of business process reengineering concepts, methods, processes and tools to implement business process reengineering to provide a technical reference.Keywords: Business Process Reengineering (BPR) workflow (WorkFlow) process modeling一、workflow technology(一)Workflow and Workflow Management SystemAccording to international definitions of Workflow Management Coalition, workflow is the automated operation of the business process, in part or whole to the performance of the participants on the documents, information or tasks in accordance with the rules to take action and make it passed between the participants. In short, the workflow is a series of interrelated, automated business activities or tasks, work with a fixed procedure for the regular activities of a concept put forward. By the definition of good work down into tasks, roles, rules and processes for implementation and monitoring, to improve the level of production organization and work efficiency.Workflow and other management ideas, technologies, is an optimization method is optimized to work thinking and techniques, which have the following advantages:1.Main business processes can greatly shorten the processing time. In general, their daily activities, about 70% of the class activities are processes, workflow, business activity throughout the sector at all stages of planning through better business processes, parallel execution of independent activities, reduce business process does not necessary intermediate data and other methods to reduce the wait and the purpose of temporary storage space, which can greatly speed up the process of processing speed, improve peoples working efficiency and management of the standardization level.2.Use of workflow technology, quickly and easily access all relevant data and workflow, automatically become a task to provide for the relevant information needed to reduce the staff is very tedious and time-consuming data to find work. This increases efficiency, reduces management costs, thus greatly improving service quality.3. Use of workflow technology can maximize the integration of enterprise information resources available to achieve full use of resources. As workflow technology has flexibility and openness, it can ensure the enterprise information system can be extended successfully to meet the changing market environment.Workflow management system is to provide a workflow generated (including business process definition), workflow and business process workflow management and monitoring functions necessary to support a set of tools. Most workflow management system application process generally use the following four steps:(1) Process definition. The main task of this stage is based on enterprise business process a process model (workflow model) that can be handled with a formal computer language to describe the business process. Analysis and implementation process model is a necessary basis for workflow management. (2)Model analysis and process optimization. This stage is to use static or dynamic model analysis methods and tools to analyze the performance of process models, in order to find the model possible bottlenecks, deadlocks and so on, in order to improve and optimize the model.(3)Application systems development. The stage optimization model under the corresponding information systems, database systems, the implementation of workflow management software and workflow management software, integration with other systems.(4)WfMS implementation. WfMS implementation is the use of workflow management software, according to the process optimization model to create process instances, schedule and control the course of business, the implementation of activities. In this implementation process, WfMS will interact with the operator or trigger the application of system-related functions. In practical applications, workflow management systems implementation and business process reengineering are closely related. Implementation of the workflow management system is aimed to enhance the flexibility of enterprises, and can change according to market continuously improve their business processes.(2) Workflow and Business Process Reengineering Business Process Reengineering (BPR) is a thorough business process re-think and re-design. This will inevitably lead to management concepts, business processes, organizational structure and corporate culture of many multi-level change, so there must be steps to a purpose and a plan for the implementation of BPR, to ensure ultimate success. BPRs life cycle can be divided into project planning, process modeling, process optimization, systems implementation and project evaluation five stages:(1)Project Planning. The main task of this stage to develop business planning and BPR objectives. Senior leadership in this phase enterprise development through the development of business strategies to guidance from higher levels of project implementation is necessary; In addition, business leaders should also be on the implementation of the necessity and importance of BPR form of unanimity, to determine the process of recycling target. (2)Process modeling. The main task of this stage is to accurately describe the existing business processes, build business process models. Process modeling is a business process analysis and optimization design.(3)Process optimization. The main task of this stage is the stage in the process model based on the analysis and optimization of enterprise business processes. Optimizing business processes, we must give full play to the role of information technology. On the one hand, with the computer, networking and the rapid development of communication technology, information technology can provide flexible business-oriented working groups and based on communications interoperability. This may change the behavior of businesses - from the serial into a parallel mode of collaborative work. On the other hand, information technology, in particular, is based on rigorous mathematical model based on simulation analysis and optimization tools, early detection of bottlenecks and put forward reasonable optimization process or comments.(4)System implementation. This phase is mainly under the optimized process model, the re-establishment in the enterprise with new business processes that match the organizational structure, conduct training, complete business process transformation.(5)Project evaluation. BPR implementation, the need for new monitoring and evaluation of business processes to the problems found, if necessary, the process needs to be perfect again. Contrast WfMS application life cycle and the five stages of the implementation of BPR, we can see the workflow technology can better support the BPR in the process analysis, process optimization, system implementation and evaluation of the four stages of the project. In addition, because WfMS can schedule and monitor the implementation of activities, to achieve good process management and control.Thus, workflow technology has good support for BPR. In fact, the implementation of workflow technology is the most widely used BPR techniques. 二、Based on workflow technology, BPR implementation process Business processes and activities according to the complexity of the composition, based on workflow technology, the implementation of BPR can be implemented using a variety of ways. Here one of the process modeling, process optimization, system implementation and assessment of the four stages of the project content, methods, tools and related notes.(一)Set up a business workflow modelEnterprise is a complex economic, social and physical systems, must be from multiple angles to describe its business processes. Usually from the organization, resources, business processes and data to examine four aspects of enterprise business processes.(1) Organization described the organizational business units and their mutual relationship. Exist between organizational units are subordinate or collaborative relationship, to form a certain hierarchy; (2)Resources in the enterprise resource description and resource entity type attributes. Resources are the activities to implement the necessary conditions; resource entity may be the implementation of activities, that may be required for the implementation of the activities of equipment, materials or activities in the physical output of the new entity. Between the organization and resources mapping, every resource entity has a corresponding responsibility to organizational unit, the organizational unit responsible for this resource entitys use and maintenance;(3)Business process business process description, which is included in the definition of the business process activities and the logical relationship between these relationships.(4)Data from the perspective of enterprise data describing the relationship between business process and data in the data structure of relations, set up a business process workflow model is to determine several aspects of the business and its relationship process.(二)Analysis of enterprise workflow modelTransformation of the original process by the existence of irrational factors in order to improve business process performance is one of the major BPR objectives, therefore, the establishment of a business workflow model, you must analyze, identify problems and use of optimization solutions.(三)Optimization of enterprise workflow modelAfter these several times on business workflow model simulation runs and analysis of operating results, it is often to modify or re-define the workflow model simulation environment. This is because the original workflow model through simulation and found that the unreasonable structure of the model or relationship, you need to make changes or adjustments. Modify or adjust the model to achieve the following two purposes: （1）Adjust the workflow model and the actual business process to improve their consistency. The model started with the actual business process possible inconsistencies, the simulation analysis can be part of that model, which does not match with the actual situation, then modify the workflow model by repeatedly and run the simulation process, adjusting the model to make it step by step approach the actual business process. （2）Optimization of the workflow model, the final optimized business process. Through the implementation of simulation and analysis of simulation results may be unreasonable that where the current workflow model, such as rising costs caused by an irrational allocation of resources, reduced efficiency. At this time, by modifying the model structure or parameters, re-run the simulation, you can find a better solution to optimize workflow model, the ultimate purpose of business process optimization. Can use sever
