| E. What kind of businesses allows to simplify the control func-
tion? F. Why is not necessary to write a code with this new system? G. What new name can be given to this new system? Designing executable business processes as a programming paradigm 1. Despite the fact that the first analogues of modern business pro- cess management systems (at that time they were called workflow sys- tems) appeared more than fifteen years ago, until recently, most of the process management works were limited by the study of production activity of enterprises, identification of repetitive chains of actions, formalization and integration of these chains into completed business processes, analysis of selected business processes, and development of recommendations for changes in business processes so that at the same time the operating efficiency of the enterprise increased. This did not imply automated execution of business processes. 2. The use of computer systems was limited only to business process modeling. That is, after the development or modification of a business process it was introduced to organizations by administra- tive methods, which are long, clumsy and expensive. In recent years, quality changes occurred in this field. Currently, enterprises have been actively implementing computer systems directly executing business processes in the computer environment which are called the business process management system (BPMS). These systems dis- tribute tasks to the executors and monitor their implementation. The sequence of tasks is determined by the business process diagram. 27 Control points move across the diagram; in the design modes c ontrol points generate tasks for the executors. 3. Thus, at an office-type enterprise, an analogue of the production line appears: this mechanism makes it possible to exclude routine oper- ations from the employees’ actions, inefficient procedures related to information search and transmission, and significantly to increase the rate of employee interaction. This is due to the fact that by using BPMS, employees accomplish received tasks sticking to receiving data required for task execution from other employees; they transmit the results of their work to other employees; and they study the job descrip- tions. All information needed to perform the task appears on the em- ployee’s computer screen. 4. At enterprises with stable recurring chains of operations, the use of BPMS provides other advantages: significantly simplifies the control activities for works in progress and increases the transparency of busi- ness operations; improves the enterprise product quality: through auto- matic regulatory activity and monitoring tools to observe all rules pro- vided makes it possible to promptly change business processes in re- sponse to the changing business environment of the enterprise; makes it possible to solve the problem of enterprise scale integration; reduces the cost of enterprise automation, and improves the rate of software development and reliability. 5. Let us explain the last item in the list. Reducing costs is one of the reasons for selecting a process automation option. In the traditional approach, at the beginning a detailed technical project (in the form of a plain text) is drawn up. This is approved by the customer, and subse- quently it is converted to program code by software programmers. Au- tomation based executable business processes makes it possible to elim- inate duplication: in this case, the analyst immediately develops execut- able business processes, which are approved by the customer and do not have to be translated into a program code. Therefore, the develop- ment time and costs of the work of the executors are significantly re- duced. Automation based on executable business processes makes it 28 possible to quickly adapt the development to changing problems and new ideas started up in the course of development, to reduce develop- ment costs, to reduce the technical support costs, and significantly to reduce the cost of modifications and maintenance. 6. Thus, system implementation, customization and management, based on executable business processes prove to be faster and cheaper as compared to traditional automation in which separate application components are developed for various problems and functions. These advantages (faster, cheaper, easier to support and maintain) coincide with the paradigm advantages of object-oriented programming as com- pared to procedural programming. By analogy, the activity of designing executable business processes can be called a new programming para- digm. жүктеу/скачать 1.33 Mb. Достарыңызбен бөлісу:
