Production Process Map

Basics Recommended Format

Generic Example

Basics

• Production Process Map An evolution of a production flowchart, identifying

• Inputs – What’s needed at this step

• Outputs – What’s the product/result of this step

• Key Activities – What actions yield the step’s output Processing of inputs and previous steps’ outputs

• Safety Critical Characteristic (SCC) Notation All SCC-related information employs red color font or shapes Non-SCC information employs black color font

Recommended Format

Contractor format is acceptable, provided the alternate format is explained (as in the following slides)

“1.1” means this is a 2nd Level Map of Level 1’s Step 1

Red box means there is an SCC created or detected at a lower level Map

Red Letters in Input, Output or Key Activities mean the SCC is created or detected at this very point in the Map

Safety Critical Characteristics (SCCs) Identified in this Map

Code Description A Material Structure Unsound

B Interface Thread Incorrect

C Leak Rate Over Max

D Presence of Interface Holes

E Incorrect Assembly

• Identify what SCCs are portrayed within the map Defects herein are used solely for illustration

• State “No SCCs in map” for submittals without SCCs

Topmost Level

• Steps 1 & 4 identify the creation and detection points for the Safety Criticals (red text).

A lower level map may not be necessary

• Steps 2 & 3 identify Safety Criticals are either created or detected or both in a sub-processes.

A lower level map is necessary

Step 2 Detailed [1/2]

• Sub-Steps identify creation and detection of SCCs, as well as proactive measures to prevent them (e.g., in-process check)

Sometimes the process inputs can be enable creation of SCCs

• Ovals are off-page connectors Disposition off-page connector refers to SCC non-conformance process handling
