Since Process Model was designed specifically to conduct process simulations, it has extensive features that aid in this endeavor. Users create entities, such as phone calls or mortgage applications, and activities that are performed on these entities. They also create resources such as people and pieces of equipment, and assign resources to activities. These elements are all combined into a visual map of the process that depicts the entry of each entity into the process, the subprocesses it goes through, and the outputs.
For each entity, activity, and resource, various parameters are manipulated to provide precise control over the process simulation. For each entity, such as a support call, users can set the specific input volume,and input timing. For each activity such as handling a call, the user controls the cycle time average and cycle time variation. Resources can be assigned differentially to multiple tasks, and costs can be set differentially as well. Multiple types of entity, such as support calls and sales calls, can be handled within a single model.
Once the parameters have been set, the simulation is run and reports are generated. Users can run the simulation for a set period of time, and it can be viewed in real time to see how the entities are processed, or run at high speed so that results are obtained quickly. Reports provide detailed information about the volume processed, the cycle times for the process overall and for subprocesses, and the costs, and the amount of value-added (VA) vs. non-value-added (NVA) work. Resource utilization data is also available.
This is just a brief explanation of the many ways users can control all the aspects of a process simulation. The program is quite powerful and should allow Six Sigma project teams to examine their existing processes and any potential improvements they are considering.
