Clarification of the scope of responsibility is important

The BOMs are managed within the scope of responsibility according to the use of application such as managing a BOM by scope of responsibility (role), clarifying the scope of responsibility and manage information according to the operations. It is important to manage and takeover the upstream phase information (Parts, BOM, Drawings) and link it to the downstream phase due to the changes occurred in the operations of upstream phase.

Integrated of multiple BOMs such as E-BOM and M-BOM

Since BOM is getting diversified according to the purpose and use of each application for each process and departments and overall lead time is also getting longer due to modification work of each BOM associated with engineering change and hence there is a possibility of frequent occurrence of errors while reflecting the changes made at E-BOM side to the M-BOM side.

In order to reflect such changes in a timely and accurate manner, the BOM by each application are centrally managed in a database with multiple tables (E-BOM, M-BOM, etc) and the relationship between multiple BOMs such as E-BOM and M-BOM are maintained in a common system with Integrated BOM management. This way one can understand quickly and accurately the level of impact at the time of engineering changes and can also communicate the contents of such changes accurately when changes are required.

It can be said that this process is the key to matching information related to manufacturing with goods. Furthermore, it is considered that the key method is the linkage of information (digital thread) between all processes from planning, sales, engineering, manufacturing and service in the realization of the cyber-physical system (digital twin), as well.

This time, we have explained a management approach for multiple BOMs. In the next column we will introduce a case study how Obbligato users deal BOM structure and management.
