Single Bill of Materials

Adopting a Single Bill of Materials (BOM) Strategy for Engineering and Manufacturing Integration

You think BOM is a simple “stückliste” ?

BOM is a very complex structure

Data is complicated. Each department demands different data.

Is there a single “master” BOM?


'The question is,' said Alice, 'whether you can make words mean so many different things.'

'The question is,' said Humpty Dumpty, 'which is to be master — that's all.'

--Lewis Carroll--

Who is controlling BOM?

How to synchronize BOM data across the product lifecycle chain?


Vertically integrated frameworks


The challenges of multiple BOMs

#1 → BOM Transfer

#2 → Keep Item data in sync

#3 → Keep consistency of silos

Variations of single BOM solutions


Single Structure BOM Views Federated systems

Why are companies not ready for a “single BOM”?

Multidisciplinary design tools No agreement to shareData controlling behavior


Single BOM and John Gall’s law

Gall's Law:

“A complex system that works is invariably found to have evolved from a simple system that

worked.”


Single BOM maturity model

(1) Share: Access the same BOM

(2) Reference: Connects multiple elements of BOM

(3) Query: Retrieve BOM on-demand from diverse systems


SHARE REFERENCE QUERY

1

2

3

Share the same BOMAccess & edit data

Share between departmentsShare between engineers Share between contractors

How to eliminate the sync?


How to work with the “same” BoM?

1

Reference BOMMultiple CAD and PDMsCAE environmentsOther engineering silos

Elements of a BOM need to be easily referenceable in a single environment

This is “mostly” PLM problemHow to manage multidisciplinary BOM between MCAD, ECAD and software?


2

Query BoMMultiple lifecycle stages

Enterprise systems

PLM, ERP, SCM, Services

Multiple systems

How to integrate BoMs related to different stages of product lifecycle?


3

BOM management demands...

...No mistakes ...No manual typing ...No painful synchronization

Conclusion

There is no single recipe for a single BOMIt is a combination of technologies

that can do a job
