that produce a specific service or product (serve a particular goal) for a particular customer or
customers. It may often be visualized as a flowchart of a sequence of activities with interleaving
decision points or as a Process Matrix of a sequence of activities with relevance rules based on data in
has two major meanings. Firstly, it is the process of model creation as certain
object representation of the original reflecting its most important features and properties. If the model
is already constructed, then modeling — is the research (analysis) process of system functioning. The
final goal of
business process modeling
consists in achieving operational enhancement .
Business process model
is the formalized description (graphic, tabular, text, symbolical) of real-
life or expected activity of the enterprise.
It is possible to use various methods for
business process modeling
The modeling method, or the
, includes sequence of actions which should be executed for model creation, i.e.
modeling procedure, and the applied notation (language).
3 The review of notations and tools of business process modeling
It is senselessly to speak about advantages of this or that system or notation until the main
objectives which this project has to solve aren't defined. In this work I compare
the most popular
notations used for the description of business processes
(EPC and IDEF).
One of the most important aspects of the description of business process model is the reflection of
the operating influences, feedbacks on control and control procedure control on the model. Control
procedure can be reflected in the ARIS EPC notation only by means of the incoming documents
indication. Unlike ARIS, each procedure in the IDEF0 notation must have at least one control
response. If we show only sequence of procedures performance at creation of the model without caring
of reflection of the operating documents and information, these models will have low value from the
point of view of the analysis and further use.
If we try to reflect all conditions and restrictions defining performance of functions, it will be
required to describe a large number of events and the input information, and the model will become
difficult and badly readable. The notation of IDEF0 hasn’t got these disadvantages.
Thus, IDEF0 notation is useful for small on scales (small and medium-sized enterprises, 2-5
people in group of consultants) and duration (2-3 months) projects. ARIS EPC notation is useful for
large and/or long projects .
Within this work the one-time project of the decision-making process description by means of an
ELECTRA method will be considered.
Both notations (IDEF0 and ARIS EPC) have significant
advantages and disadvantages, also they complement each other. It is decided to model the
process with the use of both notations for the purpose of their comparison and finding the best
of them in this situation.
Today there are a lot of various program tools for working with business process models from
simple graphic editors to full-fledged multipart ВРМ-systems. In this work the choice was made in
favor of Business Studio system. Advantage of this system consists in possibility of use of the most
popular notations: IDEF0, Process (Basic Flowchart), Procedure (Cross Functional Flowchart), BPMN
2.0, EPC. Thus, this system will be suitable for the comparison of IDEF0 and ARIS EPC notations
best of all.
