Process Modeling
- Business processes can be quite complex
- Process model: any abstract representation of a process
- Process-modeling tools provide a way to describe a business process so that all participants can understand the process

Flowcharting Process Models
- Flowchart
- Any graphical representation of the movement or flow of concrete or abstract items
- Clear, graphical representation of a process from beginning to end
- Uses a standardized set of symbols
- Process mapping
- Often used interchangeably with flowcharting
- Specifically refers to activities occurring within an existing business process

Extensions of Process Mapping
- Hierarchical modeling: ability to flexibly describe a business process in greater or less detail, depending on the task at hand
- Modeling software that supports hierarchical modeling
- Provides user the flexibility to move easily from higher-level, less detailed views to the lower-level, more detailed views

- Matches the logic and structure of SAP’s ERP software design
- Two structures: events and functions
- Events: a state or status in the process
- Functions: part of the process where change occurs

Process Improvement
- Value analysis
- Each activity in the process is analyzed for the value it adds to the product or service
- Value added is determined from the perspective of customer
- Real value: value for which the customer is willing to pay
- Business value: value that helps the company run its business
- No value: an activity that should be eliminated

Evaluating Process Improvement
- Disrupting the current process to make changes can be costly and time consuming
- Dynamic process modeling takes a basic process flowchart and puts it into motion
- Uses computer simulation techniques to facilitate the evaluation of proposed process changes
- Computer simulation
- Uses repeated generation of random variables that interact with a logical model of the process
- Predict performance of the actual system

ERP Workflow Tools
- Workflow tools
- Software programs that automate the execution of business processes and address all aspects of a process, including:
- Process flow (logical steps in the business process)
- People involved (the organization)
- Effects (the process information)
- ERP software provides a workflow management system
- Supports and speeds up business processes

Implementing ERP Systems
- Late 1990s: many firms rushed to implement ERP systems to avoid the Y2K problem
- Since 2000: pace of implementations has slowed considerably
- Most Fortune 500 firms have implemented an ERP system
- Current growth is in the small to midsized business market
- Implementation of ERP is an ongoing process

Implementation and Change Management
- Key challenge is not in managing technology, but in managing people
- ERP system changes how people work
- To be effective, change may have to be dramatic
- Business processes that are more effective require fewer people
- Some employees may be eliminated from their current jobs
Concepts in Enterprise Resource Planning, Fourth Edition

Implementation and Change Management (cont’d.)
- Organizational change management (OCM): managing the human behavior aspects of organizational change
- People do not mind change, they mind being changed
- If ERP implementation is a project that is being forced on employees, they will resist it
- When employees have contributed to a process change, they have a sense of ownership and will likely support the change

Summary (cont’d.)
- SAP’s system landscape was introduced to show how changes to ERP system during implementation (and beyond) are managed
- Most challenges to ERP implementation involve managing personnel and their reactions to the change, rather than managing technical issues
