STEP	WHO	WHEN	INFO TO USE	WHAT TO DO	RESULTS
1	Machining Department Supervisor Manager or Programmer	Upon receiving Engineering Change Notice, drawing revision, specification, purchase order (PO) or other information that might affect an MPS	Job Order, written spec, print or advice from machinists or others; own observations; MPSs	Review new information and MPS (if any) and identify any questions which need to be resolved; work with any team member, customer or supplier as appropriate to resolve questions and reach agreement on what is needed in the MPS(s); determine how well current MPSs meet the needs identified; if any customer or reference specifications (other than dimensional) are involved notify QA Manager per TOP-TPSMM; ensure that there is an Operation and Inspection Order set up for each machining operation, verify that all Inspection Orders clearly specify "who", "what", "how", "when",  and "how many" for each operation; verify that all operational and inspection issues related to handling storage, packaging, preservation and delivery are covered. NOTE REGARDING WELDING OPERATIONS; Welding is a "special" process whereby the results of the operation cannot be fully determined without destructive testing. For any welding operation the MPS must be specific concerning all details of the process (gage settings, amperage, wire, etc.) and of the welder's qualifications (team position).	Clear, agreed-to specifications and process plan; decision regarding how MPSs should be changed (if at all); QA Manager notified if change may be needed
2	Machining Department Clerk	Upon receiving new information from Supervisor, or feedback from machine shop personnel	Marked up MPS with redlined changes, or new information	Change MPS on computer to reflect new info; be sure MPS revision date is updated on computer; route to a second person approved to create MPSs (Supervisor, Manager or Programmer) for review and approval (both new and updated MPSs get reviewed).	Updated MPS in data base; MPS change routed to reviewer
3	Machining Department Supervisor, Manager or Programmer	Within 1 week of receiving MPS change for review	MPS; revised drawing, customer specification or other data deemed needed	Review MPS versus specs and other documentation; for welding operations see note in step 1; if any problems found or potential need seen notify Engineer or Programmer, so note on MPS; if okay, approve MPS.	MPS routed to Clerk, either approved or disapproved, with any problems or possible need for further consideration noted
4	Machining Department Clerk	Upon receiving revised MPS	MPS	If problems noted on MPS, return to step 1 (or, if minor, step 2); if approved, send MPS to Programmer if NC program changes are potentially required.	After MPS update approved, MPS routed to Programmer if program changes are possibly needed
5	Programmer	Upon receipt of revised MPS	MPS; input from Leadman, Manager, or Engineer	Change NC programs as necessary per TOP-MORDR to reflect MPS change.	NC programs updated to reflect relevant MPS changes
