A business process modeling is a collection or group of related activities or business processes that produce a specific service or product. Business processes are visually represented as diagrams of simple box with arrow graphics and text labels, better known as Business Process Models.
Business Process Modeling Overview:
Business Process Modeling(IDEF0) is the first step in Business Modeling and it is followed by Process Flow Modeling(IDEF3) and Data Flow Diagrams(DFD). In Business Process Modeling, an organization’s functions are represented by using boxes and arrows. Here boxes represent activities and arrows represent the information associated with an activity. Input arrow, Output arrow, Mechanism arrow and Control arrow are the different types of arrows that are used in business process modeling.
The business process modeling is started with a context diagram and it provides a brief overview about the organization’s activity. In order to understand the activities of an organization in a detailed manner, the context diagram is then decomposed into many sub activities diagrams.
Similarly decomposition of context diagram is done in process flow modeling and data flow diagrams. Context diagram is similar to a conceptual data model in data modeling. The following example gives the layout of the context diagram.

Quite often it is necessary for an organization to revise and re-examine it’s decisions, goals, targets etc., in order to improve the performance in many ways and this activity of re-engineering is called as Business Process Re-engineering which is also known as Business Process Re-design or Business Process Improvement.
Analyzing present business process diagrams, process flow diagrams(work flow diagrams) and data flow diagrams may lead to success in business process re-engineering since these diagrams are very powerful in visualizing the activities, processes and data flow of an organization.
Business Process Re-engineering Examples
The entire organization’s business processes or an individual department’s business processes can be re-engineered according to the needs of an organization.
For example, a bank may have many activities associated with it like investing, credit cards, loans, etc., and they may be involved in cross selling(e.g. insurance) with other preferred vendors in the market. If the credit card department is not functioning in an efficient manner as the way the bank expected, it might re-engineer the “credit card” business process.
In this situation, bank may think about decreasing the interest rate, offering promotion, redemption, balance transfers etc., to the customers in order to facilitate the performance. This would lead to re-engineer or re-design the current bank’s credit card process. The net effect is the improvement in performance of credit card division and conversely, if anything goes wrong, major losses are also expected.
Computer system’s infrastructure, competition, financial strength, expenses reduction, customer satisfaction, product quality, better management, employees involvement are some of the areas that an organization is interested to do business process re-engineering and change the existing processes.
Project Infrastructure
An organization may migrate from X database to Y database for better performance, storage capabilities and reliability.
Competition
An organization may buy a new and sophisticated application in order to overcome the competitive pressure.
Financial strength
Many small and big companies need money to expand their business and in this situation, they may get loans, or issue shares etc.
Product Quality
A calling card distributor may buy good calling cards from the vendors that are good in quality, time and easy connection.

- BPM’s data flow models visualize the data flow within the organization and business-to-business transactions.
- BPM’s decomposition diagrams for business process modeling, process flow diagrams and data flow diagrams visualize the processes and activities in a detailed manner.
Workflow:
- BPM’s workflow helps to define, create, execute, automate and manage processes within the organization and business-to-business-transactions to get more productivity.
Documentation:
- The entire business process procedures can be documented in a shared multi user repository. This provides technical and non-technical persons to understand the different processes that occur in each departments of the organization, its performance and the outcome of each business processes.
