Engineering prints can present some difficult issues when working on changes.

• Maintain a master list of current prints in your document control system.
• If prints are distributed, they must be controlled.
  • Operators verify documents against the master list.
  • The Document Control Coordinator marks prints with a job number.
  • The print is good only for the job number.
• Prints and documents of external origin must be included in your document control system.
  • Customer prints
  • Industry regulations
  • ISO 9000 standards
  • References used for your documentation
• Your master list should have a section (Documents of External Origin) containing the following information about each document or print.
  • Document name
  • Current revision
  • Document location(s)
  • Document number (assigned by your company)
