Anyone who has dealt with Bill of Materials (BOM) knows about the challenges and complexities involved with it. Sometimes we get asked, managing a single BOM itself is cumbersome, then why do we even need another one in the form of a Manufacturing Bill of Material (mBOM)..?

What we have seen with our customers  is that, when there is only one BOM then it is usually owned by the engineering department (CAD BOM/ eBOM) and will be available for  the Manufacturing Department as  a “read only”. This is not good enough for the manufacturing teams as they need to author and add data specific to manufacturing , for example  manufacturing specific consumable parts like glue, oil or Tool Fixtures and such. Another key factor is how the BOM is structured; typically eBOM is structured around organization systems and functions and represent the product architecture, but for manufacturing team a mBOM needs to be  organized according to the manufacturing assembly order.

When customers need to work towards the industry 4.0 goal, they need to have  smarter manufacturing  solutions and systems that provide more ways to capture the manufacturing business intelligence and then suggest solutions based on the previous patterns. With this in mind they need to invest in  manufacturing BOM authoring and management area. During a mBOM adoption, the key is not to recreate the data that’s already in eBOM, but to reuse the eBOM and add additional information specific to manufacturing. That way there is both reuse and traceability of the data.

At a high level mBOM creation automation solutions exist in multiple flavors

  1.  Recipe based mBOM:  In a recipe based mBOM, customers can initiate the mBOM creation via pre-configured  templates pointing to eBOM. Based on the recipe stored with the template it will automatically fetch the engineering parts into mBOM. This kind of solution helps customers who have heavy standardization in their product offerings.
  2. Reusable Manufacturing Assembly: In such a solution, customers can leverage the same manufacturing assembly across multiple product lines to reduce the design, development and procurement costs
  3. New Offline Processing Solutions: This approach is to tailor the mBOM creation process and application to the customer need using customization. This standardizes and automates the process to capture the business intelligence and its reuse via customization.
  4. Smarter Validations: Such solutions suggests what’s next to the business users, that way users spends less time discovering the problem and more time solving it.

Over all value of such solutions is not just the flexibility it offers the manufacturing team, it also reduces manufacturing process planning and execution lead time with improved structure accuracy and significant reduction in change reconciliation processing time.

More often PLM starts as a CAD/Design data vault for many companies, later evolving to a design data exchange platform .  Most successful companies are taking PLM beyond just a design data exchange and access control platform; to a knowledge driven decision support system.  This means PLM not only needs to manage the multitude of information generated at various stages of the product lifecycle , but also capture the product development knowledge and feed it back to the product lifecyccle. For example, the requirements and design for a newer version of a product  needs to be also driven by the knowledge elements captured from the previous version’s lefecycle, from inception to design to manufacturing and service.

When PLM stays just in the Design Engineering world, it’s constrained to exchange information and capture knowledge from downstream stages managed by disconnected, silo based systems. This results in engineers spending huge amount of time in data acquisition tasks. Industry studies shows that information workers spend 30-40% of their time only for information gathering and analysis, thus wasting time in searching for nonexistent information, failing to find existing information, validating the information or recreating information that can’t be found.

Quality escapes is another challenge with such disconnected systems when product doesn’t confirm with the engineering definition. Non-conformances found on the shop floor  are costly to review and dispose and even more severe when the product is already on service. Reconciling change is also extremely challenging, especially its downstream propagation, resulting in significant productivity losses. Slow change processing along with quality escapes cause delays in new product introduction affecting the overall ability of the companies to compete.

The first step towards transforming PLM to a true knowledge driven decision support system is to extend it to the CAD/CAM/CNC process chain, thus taking it to the shopfloors. Such a solution helps to establish a  continuous loop from Engineering into the shop floor for operations management and manufacturing execution systems (MES). Such a continuous loop system provide more ways to capture the business intelligence and then suggest solutions based on the previous patterns. Then it’s much easier to capture information and use analytics to synthesize valuable knowledge elements compared to the fragmented solutions many companies have today.  It’s also a foundational element for establishing a Digital Twin per Industry 4.0 vision
