Simulator (disambiguation) A simulation system, process or deviceSimulator (gastropod), a genus of freshwater snails in the family Planorbidae.Business process modeling (BPM) in systems engineering and software engineering is the activity of representing processes of an enterprise, so that the current process may be analyzed and improved. BPM is typically performed by business analysts and managers who are seeking to improve process efficiency and quality. The process improvements identified by BPM may or may not require Information Technology involvement, although that is a common driver for the need to model a business process, by creating a process master.
Change management programs are typically involved to put the improved business processes into practice. With advances in technology from large platform vendors, the vision of BPM models becoming fully executable (and capable of simulations and round-trip engineering) is coming closer to reality every day.

Business process modeling plays an important role in the business process management (BPM) discipline. Since both business process modeling and business process management share the same abbreviation (BPM), these activities are sometimes confused with each other.
BPM addresses the process aspects of a business architecture, leading to an all encompassing enterprise architecture. The relationships of business processes in the context of the rest of the enterprise systems (e.g., data architecture, organizational structure, strategies, etc.) create greater capabilities when analyzing and planning enterprise changes. For example, during a corporate merger it is important to understand the processes of both companies in detail so that management can correctly and efficiently identify and eliminate redundancies in operations.
The graphical representation of business process information has proven effective for presenting it to business stakeholders, including business analysts and system developers. Visual modeling languages used to represent business processes include Business Process Modeling Notation (BPMN) and the Unified Modeling Language (UML).

Business process modeling has always been a key aspect of business process reengineering (BPR) and continuous improvement approaches, such as Six Sigma. For routine business activities, BPM tools such as Provision, Intalio, K2 [blackpearl], Axway, Lombardi, Holosofx, Holocentric Modeler and TIBCO are used in order to represent a business process, to run a simulation of the process and for communication purposes. For innovative, adaptive, collaborative human work the techniques of human interaction management are required........
