Usage of business process tools for modeling requirements on system changes

摘要

Company information environment (which means data and applications working with these data) has to fully support company business processes. Outputs of these processes are the products (production sphere) or services (public administration institutions). Nevertheless the company development and external influences (e.g. customers behaviour, changes in data requirements, the impact of competition, the influence of suppliers, customers influence, legislation changes etc.) lead into the processes changes, which are further reflected in demands on used information environment. The institutions (and their customers) need data from 'classical' transactional systems and from geographic information systems (for spatial decision making). Requirements for changes of spatially oriented data are more frequent than requirements for changes in classical information systems. The reason is that technology conditions are developing, territories are changing, demands of users on spatial data are changing, etc. Another factor is that IT elements are today often outsourced, which enables company to focus on its core business activity. Change requests on information systems are repetitive and so they are actually repetitive instances. But it is also necessary to keep in mind specific conditions of outsourcing where the harmonization and sequences between contracting authority and vendor is significant and important. Therefore it is suitable to run RFC (request for change) instances as the instances of modeled change process, which is what this text is being concerned with.
