Please describe what Business Process Mapping is and why it is used

Business Process Mapping describes the capture of a set of business activities that deliver an outcome.  Mapping is usually performed using visual tools that use standardized shapes to indicate entities.  Mapping involves capturing activities, the roles performing the activities, systems and tools used to execute the activities and inputs and outputs from the activities.  Process mapping is frequently conducted in cross functional workshops with a facilitator capturing the activities performed by Subject Matter Experts (SMEs).  Common uses of process mapping include:
* automation
* compliance documentation
* business process improvement
* standardization
