Process maps help you to understand and to communicate the activities, or
steps, in a process. Process maps also help you to see the relationship between
inputs and outputs in a process, identify key decision points, and uncover
rework loops.
A process map answers the following questions.
- Which areas of the process
show the greatest opportunity for improvement?
- For a specific project, where
does the process start and end?
- What are the inputs and
outputs of each step in the process?
- Which steps are the
bottlenecks and sources of defects?
- Which steps have a direct
impact on customer requirements?
- Can you simplify, combine, or
eliminate steps in the process?
How-to
- As a team, determine where
the process starts and where it ends, then walk through each step of the
process.
- Identify the data associated
with each step of the process. Consider the following items.
- Activities: Names of the
steps in the process map.
- Inputs: X variables that
can influence the output of interest, either directly or indirectly.
- Outputs: Y variables
that depend on X variables.
- Process data:
Information that further defines the characteristics of a process, such as the
yield or
DPMO at each step.
- Lean data: Information
that is used to identify and eliminate waste, such as resource utilization or
cycle time at each step.
- Record the collected
information in a process map.
