BOM management is a tough topic because those words mean something different to each company that I work with. Even within a single company, you could ask different departments and get different answers. So I venture in \u2013 knowing this is a topic often surrounded by strong opinions and heated debates!<\/p>\n<p><strong><em>Learn more by watching this webinar, &#8220;<a href=\"https:\/\/www.plm.automation.siemens.com\/global\/en\/webinar\/bom-management\/58824\" target=\"_blank\" rel=\"noopener nofollow noreferrer\">Multi-domain BOM management<\/a>,&#8221; as part of our <a href=\"https:\/\/www.plm.automation.siemens.com\/global\/en\/topic\/impact-of-plm-strategy\/59248\" target=\"_blank\" rel=\"noopener nofollow noreferrer\">webinar series on strategies to streamline product innovation<\/a>.<\/em><\/strong><\/p>\n<p>Which bill of materials management or BOM management solution is best for you?

The part bill of materials is where configurations are defined, parts get registered to orderable configurations, manufacturing effectivities are defined, and where decisions on which parts get bought from whom and where parts will be manufactured and stored. This element of a BOM is concerned with Parts \u2013 not designs. It is critical to have alignment between the Design and Part BOM definitions. For some customers, Part and Design data are contained in a single BOM. For others, business drivers require this information to be tracked separately. These and many other factors needs to be considered when discussing Master Data Management (MDM) and where this data should live &#8211; PLM or ERP. My colleague, Ashok Krishnamurthy, explores some of these issues in his blog on <a href=\"https:\/\/blogs.plm.automation.siemens.com\/t5\/Teamcenter-Blog\/Moving-Product-Master-Data-Management-closer-to-the-product\/ba-p\/291025\" target=\"_blank\" rel=\"noopener noreferrer\">Master Data Management<\/a>.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li><strong>Design<\/strong>: In a <a href=\"https:\/\/www.plm.automation.siemens.com\/global\/en\/products\/collaboration\/design-bom.html\" target=\"_blank\" rel=\"noopener nofollow noreferrer\">design BOM<\/a> (often called the virtual product definition), mechanical designers and engineering are usually focused on generating the 3D components that make up the product. Electrical engineers construct detailed PCB board layouts, wiring diagrams and component placements. Software engineers convert high-level models into source code. The dynamic nature of this work requires flexibility in how the data is organized. It enables designers to work in structures that are most effective for them. The design BOM\u00a0is critical to drive effective downstream processes \u2013 like DMU, weight roll-ups, parts catalogs, service instructions, etc. The better your design BOM, the better all those will be as well.

You&#8217;ll find some great information about how DMU can be leveraged across the organization in Mark Heinrich&#8217;s discussion about a <a href=\"https:\/\/blogs.plm.automation.siemens.com\/t5\/Teamcenter-Blog\/A-Visual-Product-Experience-Not-just-for-designers-anymore\/ba-p\/365929\" target=\"_blank\" rel=\"noopener noreferrer\">visual product experience<\/a>.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li><strong>BOM Configuration Management<\/strong>: <a title=\"BOM configuration management\" href=\"https:\/\/www.plm.automation.siemens.com\/global\/en\/products\/collaboration\/bom-configuration-management.html\" target=\"_blank\" rel=\"noopener nofollow noreferrer\">BOM configuration<\/a> management is the discipline of managing the content of the product definition throughout its lifecycle. From planning (what options do we want to offer to our customers) through development (which design pieces go together to support all valid configurations) and manufacturing (which configurations can be produced at which manufacturing location). BOM configuration management includes the evolution, maturity, and release of product data. We&#8217;ve gone into more detail on this topic in several recent discussion, including the blog series about <a href=\"https:\/\/blogs.plm.automation.siemens.com\/t5\/Teamcenter-Blog\/Beyond-Product-Configurator-Software-Total-Variability\/ba-p\/325559\" target=\"_blank\" rel=\"noopener noreferrer\">product configurator software<\/a>.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li><strong>Variability<\/strong>: Product variability is part of BOM configuration management, but I\u2019ve found it\u2019s a topic that often gets a lot of attention, so thought I should call it out. Product variability management is all about engineering a product to offer solutions to meet a range of customer needs efficiently. Let\u2019s use cars as an example. When the automobile first rolled off the assembly line, it came in black. Now, when you want to buy a new car you can go to a web site to \u201cbuild\u201d the exact car you want \u2013 from the color, to the transmission, to the stereo system etc. Companies have to find a way to offer the diversity customers are demanding while still remaining profitable (you can\u2019t build a custom car for every person \u2013 but you want them to think that you do!)\u00a0\u00a0\u00a0For some companies, product variability management is more about serving various markets. You have basically the same product that needs to be \u201ctweaked\u201d for different markets. That might include packaging with the correct local language, different components based on regulations or availability etc. Effective <a href=\"https:\/\/blogs.plm.automation.siemens.com\/t5\/Teamcenter-Blog\/Product-Variant-Management-Delivering-the-Variability-Your\/ba-p\/288803\" target=\"_blank\" rel=\"noopener noreferrer\">product variant management<\/a>\u00a0is becoming more and more critical to success.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li><strong>Architecture:<\/strong> To better manage configuration and product variability, product architectures help to organize similar content across several products. A product architecture provides a stable definition of how your product is broken down and organized, and can be used consistently for similar products or for the same product as it evolves. For many customers today, this product breakdown is simply part of the overall product structure. We\u2019re starting to see more and more that this approach is not sufficient. Different users may have different ways that are best for them to organize the product (i.e. some users may prefer a system-based breakdown, a breakdown based on spatial zones, or one based on manufacturing assembly sequencing).\u00a0For this additional level of flexibility, the <a href=\"https:\/\/blogs.plm.automation.siemens.com\/t5\/Teamcenter-Blog\/Product-Architecture-Breakdown-Guides-Product-Engineering\/ba-p\/306102\" target=\"_blank\" rel=\"noopener noreferrer\">product architecture<\/a> can be separated from the product content so the product content may be organized and navigated in different ways for different users. Many companies are turning to this approach to help rapidly respond to customer needs and introduce new products quicker.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li><strong>Coordinated Change: <\/strong>Coordinating <a title=\"BOM change management\" href=\"https:\/\/www.plm.automation.siemens.com\/global\/en\/products\/collaboration\/bom-change-management.html\" target=\"_blank\" rel=\"noopener nofollow noreferrer\">BOM change management<\/a>\u00a0across various product representations is an issue that is gaining more and more visibility as products grow more and more complex. For example, the scope of what makes up a single change often includes mechanical and electrical design updates, part changes, documentation updates, introduction of a new option or rule, etc. To effectively manage \u201cchange\u201d, you have to be able to collect together and coordinate all those pieces.

But I think it\u2019s ok \u2013 it helps me get to this next part.<\/p>\n<p>To us, it has become abundantly clear that one of the problems that come up when you talk about bill of materials or BOM management is that the scope of what people might mean is so broad.
