Business process modeling for e-business describes how a business completes missions or tasks. A single model focuses on a one business task and its completion. It takes many process models to illustrate how a business carries out its daily functions.
Processes can be made up of many actors (people, organizations or even systems) simultaneously performing a wide array of tasks. The actors must complete their tasks in a logical, coordinated process to accomplish the overall goal. Most processes have critical decision points where the process flow can either focus on the status of the system or a specific process execution.
A process can look very different when described from the viewpoint of different actors. A business process modeling methodology needs to be able to represent these different aspects of a process.
The visual aspect of business process modeling makes it critical in the e-medicine arena. Some popular applications for this practice are:
Business process models can be instrumental in the re-engineering process. They can be used to develop various simulations for testing processes on inputs that have yet to occur. They can also be used to create systems automating the very processes they model. Programmers can use the process model as a guide in developing information systems.
Some common methodologies making use of business process modeling are:
Swim lane business process maps are flow charts showing an organization’s structure. A swim lane is a visual tool used in process flow diagrams, differentiating and assigning responsibilities for the sub-processes of a business plan. Swim lanes can be sorted and arranged either horizontally or vertically.
Swim lane flowcharts differ from other flowcharts because their processes are sorted visually by placing them in their own areas labeled lanes. Parallel lines break the chart into those lanes, with each one representing a person, group or sub-process. Lanes are then labelled to show company structure and organization.
When used to diagram a business process involving more multiple departments, swim lanes clarify the needed steps and who is responsible for them. They also show how delays or mistakes are most likely to come about.
Electronic health record workflow management systems heavily rely on process definitions provided during business process modeling. Most EHR workflow management systems implement certain basic workflow operators, such as sequence, synchronization and exclusive choice. Business process modeling provides framework and language for EHR in the medical industry.
