Measurement Theory - Process Mapping What is process
mapping?
Identifying all the steps in a process the inputs/outputs, and
controls in each step, understanding the responsibilities for each
step and mapping the steps as they should occur.
Why process mapping? Problems are always the result of a
process. A problem
arises in the process and causes a certain result.
A process can only be discussed when it is understood.

Measurement Theory - Process Mapping Who should be involved?
Process mapping should involve all the stakeholders in the
process.
The people involved in the daily process execution are critical
to the process mapping.
What is the goal?
To develop a common, holistic understanding of the process, the
process steps and how they work.
To create a tool for the quality improvement.
