The purpose of this work was to study the possibility of connecting two effective techniques (activity table and simulation) for carrying out business process modeling and improvement. The activity table is a technique for process modeling and improvement. Business process modeling is done by identifying the business processes and is continued by choosing a process, defining its work processes and activities. Process improvement is achieved by simulation of the activity table, suggesting changes and improvements, and giving solutions for existing problems. Then the simulation process was run using iGrafx software. The problem of conducting a surgery is introduced and used as an example to test the technique.
