Models support design Simple things do not necessarily need a model The solution is relatively easy to construct Few people collaborate or use the solution(often only one) The scope of future needs is unlikely to grow substantially Certain complex systems must begin with a design or another abstract representation Construction of an office building needs architectural plans and a mocK-up for visualIzation Modeling provides visualization of the entire system Allows assessment of various options Communicates design risks before actual construction Business Process Analysis and Modeling 2/2/202

Models are the foundation for complex analysIs a model serves as an abstraction of the item being built Business analysts, engineers, scientists, and other professionals who build complex structures or systems create models Sometimes the models are physical Scaled mock-ups of airplanes, houses, or autos Sometimes the models are less tangible Financial models, market trading simulations, electrical circuit diagrams Traditional flow charts are a common method for representing the paths ot a process Structure charts, or simple block diagrams with arrows, are often used on whiteboards Business Process Analysis and Modeling 2/2/202
Models are the foundation for complex analysis 18 Business Process Analysis and Modeling 2/2/2021 A model serves as an abstraction of the item being built. Business analysts, engineers, scientists, and other professionals who build complex structures or systems create models. Sometimes the models are physical. Scaled mock-ups of airplanes, houses, or autos Sometimes the models are less tangible. Financial models, market trading simulations, electrical circuit diagrams Traditional flow charts are a common method for representing the paths of a process. Structure charts, or simple block diagrams with arrows, are often used on whiteboards
Todays business processes require modeling One-dimensional flow charts or models miss key attributes Business processes have a flow of work items and more Organizational and business information are key attributes How long does it take? How much does it cost? Who provides the service What policies, procedures, and business rules apply When is the process efficiency optimized? Process models document the business and assist in communicating organizational change to the enterprise. Once documented and shared with the organization, the process needs to be monitored and updated to provide optimal performance Corporate governance: Implementing controls to help ensure legal compliance with the Sarbanes-Oxley Act for accurate financial forecasting and reporting 19 Business Process Analysis and Modeling 2/2/202

Purposes of business process modeling Business process models serve many purposes, including: Documenting existing procedures Determining requirements for staff, systems, and facilities Planning changes to existing processes and systems Testing and analyzing existing and proposed processes s Identifying defects in your processes(bottlenecks, and so forth) Process model data can support other business applications that rely on this information: Workflow, policy and procedure documentation, application development Models visually represent an organizations current workflow(an as is model)and allow what-if scenarios for future(to-be)designs Effective models need a well designed modeling structure To understand what it takes to complete the activities Ensures consistent and complete representation of in formation Including normal operations, alternatives, and exceptions to standards Business Process Analysis and Modeling 2/2/202
