A system approach to a top down process discoveryIt is believed that a business process may be revealed using a bottom-up, but the model obtained in this way overloaded with details, are difficult to understand and often just provide a description of an individual script execution. The methods of model construction process using a top-down, highlighting all of the scripts execution is presenred. The result is a multi-level hierarchical model, suitable for analysis.

A method of determining the process goals, tasks and requirementsAn error in the business process goal setting leads to its incorrect analysis, miscalculation in the formation of the requirements for the projected IT system. In this paper we systematize the terms: a goal, a task and a requirement, that it is essential for the proper business process investigation. We also formulate a method for determining process goals, describe a way of identifying the require- ments by the analyses of the processes product and of the mode of process execution.

Adaptation of Bunge-Wand-Weber ontology for business process modeling
The Bunge–Wand–Weber ontology is widely used in object-oriented development of IT applications.
It shows how a real world objects are mapped to the ontology concepts. Wand and Weber suppose
that the ontological expressiveness of a modeling language used to describe the world around
us, can be assessed by investigating the mapping from a set of language primitives to a set of constructs
of the proposed ontology. One of the main success factors of the use of modeling language
or notation is its ability to provide a set of modeling primitives, which can be directly mapped to the
relevant concepts of Bunge–Wand–Weber ontology. However, the existing Bunge–Wand–Weber ontology
is not fully suitable for describing business processes. The analysis shows that the ontology
misses the concept of time, the mapping of logical operators of modeling language on the concepts
ontology remains unclear, ontology contains no concept necessary to map a performer of process
operations. The paper proposes to clarify the distinction between internal and external events, thus
introduce a category of time; adds the concept of the actor who initiates the start of the execution or
completion of the process operations; change the definition of the transformation, adding the meaning
of unit of work that doesn’t change the object, but rout it to the next operation thus allowing to
map logical operators. As a result of the proposed adaptation the Bunge — Wanda — Weber ontology
becomes adequate to the task of business processes modeling.
