PLM and ERP: Separated by a common Bill of Materials (BOM)

PLM and ERP: Separated by a common Bill of Materials (BOM)


Yesterday, I had a privilege to share my thoughts about Bill of Materials and BOM management during my keynote at ProSTEP iViP Symposium in Stuttgart. That was my first time at ProSTEP conference. The first day is over. I will be publishing  updates in my live blog here.

The discussion about Bill of Materials is always interesting and entertaining. BOM is a centerpiece of every engineering solution. As an organization you have to manage different aspects of Bill of Materials during design, engineering, manufacturing and support stages. These days, as companies are moving from selling products into services, support and maintenance BOM is getting more into the focus of discussions. After all, Bill of Materials is complex topic. On the following picture you can see multiple dimensions of BOM complexity:


In every organization, Bill of Materials has two notions  – technical and political. The first one is absolutely important. The following three characteristics are absolutely important if you think about reliable BOM management solution: 1/ ability to manage multi-disciplinary data; 2/ scalability; 3/ user acceptance. User acceptance is a tricky thing. The demands of people in an organization about BOM are different. Engineering, manufacturing, support, supply chain, sales – these organizations have want to see BOM differently.


However, regardless on the role of a person in organization, the following demands are absolutely critical: 1/ No errors (each mistake in BOM is painful and can lead to significant problems in an organization ; 2/ No painful date re-entry (nobody wants to enter information into BOM multiple times); 3/ No painful synchronization of data between PLM, ERP and other systems.


Below you can find a full deck of my presentation:

What is my conclusion? Bill of Materials and BOM is a very interesting topic. My hunch, it is getting even more in the focus of people as products are getting more complex. These days every single product is a combination of mechanical, electronics and software. Manufacturing companies are selling it as a services. Customers are demanding configurability, high quality and low cost. How to manage all these things together? The following three questions are absolutely important when you think about BOM management – 1/ How to support connected processes in an organization? 2/ How to stop synchronizing BOM between silos (PLM, ERP and others)? 3/ How PLM and ERP can support a concept of “single BOM”? Just my thoughts…

Best, Oleg
