How Close to Reality is the „as-is” Business Process Simulation Model?

What is it about?

This paper seeks to identify, systemize and elaborate implementable techniques of preparing a business process model based on the historical data, which truly reflects the real process behavior. The research has been performed in Polish telecommunications company. Authors investigate technical process of expanding cellular network. After elaborating “as-is” model, authors use ADONIS simulation tool to run a series simulations and confront simulation results with actual historical events. After this, assessment whether computer simulation model can precisely map real-life business process - and consequently act as credible basis for process improvement - is made.

Why is it important?

A fully equipped simulation model is found to allow reconstructing the historical execution of business activity with low margin for error. Hence the model reflects the business reality and can be taken as a reference model while redesigning the process. Some limitation were identified and discussed.
