Definition of Configuration Management* • Applied over the life cycle of a product • Provides visibility and controls of its performance, functional and physical attributes • Verifies that a product performs as intended • Is identified and documented in sufficient detail to support its projected life cycle * Abstracted from EIA-649 © 2003 D. N. Frank Associates
Configuration Management Data Exchange And Interoperability* • Facilitates the interoperability and exchange of configuration management data • To be most effective, the capabilities of the process, tools or systems, should embody the CM principles in ANSI/EIA-649 in conjunction with the business objects and data element definitions in EIA-836 • Provides a set of standard definitions and business objects that can be used by XML frameworks in interfacing the content elements among one or more systems or databases. • The extensible markup language (XML) facilitates data sharing and exchange among different systems • The level of interoperability between dissimilar systems is determined by trading partner agreement * Abstracted from EIA-836 © 2003 D.

ERM-114 - Rev. D What is an Engineering Change • Changing the Product Structure (BOMs) – Adding a part – Deleting a part – Changing the quantity per assembly • Changing the Part Itself – Changing specifications – New Part Number? – Changing approved sources • Changing the Routing (? ) – Changing the process sequence Do all Engineering Changes affect form, fit or function? © 2003 D. N. Frank Associates
BOM 0404 - Rev. B The 4 F Principle • Function: What does it do • Form: What does it look like • Fit: How does it interface • Fee: What do we charge for it Too many of us forget the 4 th “F” © 2003 D. N. Frank Associates
BOM 0405 - Rev. C What must the ECN Do • Tell us WHAT to change • Show us HOW to make the change • Tell us WHEN – Effectivity • Tell us WHO – Define tasks • Show us WHERE – What documents • Tell us WHY – Really explain the reasons © 2003 D. N. Frank Associates
Revision Letter Concepts Assigned To BOM 0414 A - Rev. B • • The Physical Item The Engineering Drawing The Part Master Record (? ) The Bill of Material Record The Routing Record (? ) All Customer Order Line Items All Work Order Line Items All Purchase Order Line Items How well do we do this? © 2003 D.

BOM 0414 B- Rev. A Revision Letter Concepts Attributes • • • Has an associated ECN Document Has an Unique ECN Number Has an ECN Initiation Date Has defined Effectivity Suggested Formats – Numerical prior to manufacturing release – Alpha after Manufacturing release • Omit I, O, Q, S, X, Z • After Y, to to AA, AB, etc. • MIL-STD-100 is a good guide How well do we do this? © 2003 D. N. Frank Associates
Effectivity of Change BOM 0415 - Rev. B • By Revision Letter – Engineering’s preference • By Dates – Do not use before, do not use after – Most manufacturing software does this • Other methods (needs) – Use to depletion of old part – Lot (batch) Number – Project (contract) Number – Customer Number – Purchase Order Number – Serial Number Engineering and manufacturing have differing views of effectivity © 2003 D. N. Frank Associates
Some Lessons Learned © 2003 D. N. Frank Associates
BOM 0417 - Rev. B Effectivity of Change Revisited • Engineering traditionally manages changes via Revision Letter upgrades • Engineering change systems do not always consider Effectivity • Manufacturing software systems do not do a good job of managing change by Revision Code • Effectivity dates are subject to change • Ways to close the gap – Put an ECN Czar in charge of bridging the gap – Only allow manufacturing BOM maintenance via an ECN screen with restricted access, requiring Revision Letter update and Effectivity statement Change impact must be communicated to manufacturing … quickly © 2003 D. N. Frank Associates
The Triage Principle BOM 0409 - Rev. A Engineering Change Priority Planning • A Stop work and fix – The sun will not set before preliminary action is taken • B Define Effectivity and schedule into the manufacturing planning and execution process – Plan for least disruption and part obsolescence – No more than 2 -3 working days until preliminary release • C Aggregate and hold for product upgrade – Batch release no less often than quarterly The business side of EC processing © 2003 D.

The View from the Foxhole EMBOM 9904 D Oh EBOM is EBOM and MBOM is MBOM, and never the twain shall meet, Til Earth and Sky stand presently at God’s great Judgment Seat; But there is neither Designer or Planner, border, nor breed, nor birth, When two strong [people] stand face to face, though they come from the ends of the earth!

The Germ of a New Idea EMM 9807 C - Rev. A • Understanding ERP is not enough • Doing Concurrent Engineering is not enough • Understanding PDM is not enough • Understanding SCM is not enough • These initiatives are only parts of the 21 st century unified approach Global Enterprise Resource Management A New FLA © 2003 D. N. Frank Associates
Prerequisites EMM 9807 D - Rev A • Engineering – Accept the Single BOM concept – Assume cradle to grave data integrity responsibility – Understand configuration management implications on the Master Schedule – Willingness to be an enterprise team player • Manufacturing – Accept the single BOM concept – Participate in configuration management activities – Understand Master Schedule implications of configuration management – Willingness to be an enterprise team player • Management – Be the champion of the GERM process © 2003 D. N. Frank Associates
Ten Steps to the Single BOM EMBOM 9808 G 1. Understand that the design objective is to provide effective documentation for manufacturing 2. Manufacturing and planning participate in the design process 3. Document the bills of material into the manufacturing database 4. Use the master schedule to show design status 5. Start “As-Planned” early in the design process © 2003 D. N. Frank Associates
Ten Steps to the Single BOM (con’t) EMBOM 9808 H 6. Document the design for manufacturing the first time out 7. Use the Single BOM to capture drawing numbers and revision status 8. Use the Single BOM to maintain the “As. Something” status 9. Use the Single BOM for customer and/or Government reporting requirements 10. Use the Single BOM as the catalyst for engineering/manufacturing integration © 2003 D. N. Frank Associates
A Final Thought • If we consider the bill of material as a living document that migrates from one phase to another, – We could measure the quality of the quotation against the accepted configuration – We could measure the quality of the design against manufacturing being able to build from the engineering documentation … directly – We could measure manufacturing performance against the baseline configuration – We can capture the “as-maintained” and compare to any “asbuilt” for effective maintenance and upgrade – We could measure the enterprise performance against what the customer really wanted © 2003 D. N. Frank Associates

BOM System Evaluation Quiz Score 1 to 5, where 5 BOM 0101 P is high - Rev. E o o o Does your BOM system meet real needs Is it simple and easy to understand Does it have flexibility for future growth Does it really describe the manufacturing process Are BOM functions & responsibilities focused Is there good feedback of BOM effectiveness Is the BOM a good communicator of information Is BOM maintenance simple and effective Is the BOM System cost effective Does Management participate in BOM decisions Is there only one enterprise BOM system Email responses to dfrankasso@optonline. net I’ll share results with all responders © 2003 D.
