Process Simulation Overview
Business process simulation until now has seldom been implemented. Because of tight development schedules, the plan to simulate the current “as-is” and desired “should-be” processes typically falls victim of having too little time. Simulation is a powerful tool and it is worth the time spent doing simulations before going into production. It helps run “what-if” experiments to see what the impact will be of:
• Reducing or increasing the number of people assigned to an activity.
• A sudden increase of the number of instances flowing through the process.
• Changing the approval ratio from 70% approved / 30% disapproved to a worse case 50% approved / 50% disapproved.
This can help avoid the embarrassment and cost of launching a new process with a flaw that only becomes obvious on day 3 of production. It can verify that the desired output meets the metric objectives and easily finds bottlenecks in processes and leads to breakthroughs.
Process Simulation Lab
This exercise will demonstrate how a business analyst can analyze and propose changes to business processes using Oracle BPM Studio.
The objectives of this exercise are
• Run simulations on business processes and analyze the following results.
- Throughput and process analysis
- Activity-based costing
- Resource allocation
Make changes to the process to optimize the flow
The simulation algorithm is based on discrete events and can process events in a serial fashion as they occur in time. You need to create Process Simulation Models and Project Simulation Definitions to run simulation. The Process Simulation Model captures a “What-if scenario” for a particular business process model. You can have multiple Process Simulation Models for a particular business process model. This allows you to create different simulations based on different combinations of resource allocations and activity behavior. The Project Simulation Definition is used to take the dependency and shared resources across processes in to account. It consists of Process Simulation Models of multiple processes.
The simulation does not execute the actual code of each activity within the process. However, by configuring parameters within the models and definitions, you can mimic the behavior of your business process. You need to ask the right questions to get the right response! In order to perform simulation the process needs to be complete and semantically valid.
