What are some tools and methods for analyzing and optimizing Bill of Materials and variant costs?

A software application is an essential tool for BOM management, as it can help create, edit, share, and track BOMs across different departments, stages, and platforms. A good BOM software should feature integration with CAD, ERP, PLM, and CRM systems; version control and change management; multi-level and modular BOMs; cost estimation and analysis; variant and configuration management; and reporting and visualization. Utilizing a BOM software can prevent manual errors, duplication, and inconsistency while streamlining workflows and collaboration.

This involves various tools and methods used specifically to enhance efficiency and reduce expenses. For BOMs offering functionalities for cost estimation and supplier management, digital tools such as Product Lifecycle Management (PLM) systems and Enterprise Resource Planning (ERP) are vital. Advanced analytics and simulation tools help in scenario planning and predicting cost impacts of changes in BOM configuration or material substitutions. Continuous improvement methodology like Lean Six Sigma can further optimize BOMs and variant costs.
A BOM analysis tool can be a great asset in optimizing your BOM and variant costs. It can help you compare different BOMs and variants, find and replace obsolete or expensive parts, consolidate common parts and materials, reduce complexity and variation, optimize your sourcing and procurement, and evaluate the impact of changes and alternatives. Utilizing a BOM analysis tool can not only reduce material, labor, and overhead costs but also improve your quality and performance.

It seems most users love spreadsheets. Using SQL and a recursive query I extract BOMS to a spreadsheet, I then extract costs associated with parts, labour/ohead etc.. Basic lookups and a few formulae later you have "costed BOMS" in a spreadsheet. The users can then use the spreadsheets to do what if analysis WITHOUT affecting the system data. Of course, if they do find some startling options we can submit a change request for approval and update system data.
A BOM optimization tool can be a great help in enhancing your BOM and variant costs. It can assist in defining and prioritizing design criteria and constraints, as well as generating and evaluating different design scenarios and solutions. Furthermore, it can optimize product features, functions, and attributes, while maximizing your value proposition and competitive advantage, and minimizing risks and trade-offs. Ultimately, using a BOM optimization tool can result in increased customer satisfaction, market share, and profitability.

In an industry where we make to print this is not a real option. Prior to implementing a BOM we have already "optimized" it to make sure we meet the customers specification/drawing requirements etc. Perhaps in a bakery or "mixing plant" I can see the real need for this as alternatives can be a big issue for them.
A fourth tool that can help you refine your BOM and variant costs is a BOM simulation tool, which can be used to test and validate your product design and manufacturing processes prior to production. This tool can simulate the behavior and performance of your product under various conditions and scenarios, allowing you to identify and resolve any potential issues or defects. Additionally, it can be used to verify compliance and quality of your product, estimate the time and resources needed for production, and predict the demand and profitability of your product. By using a BOM simulation tool, you can avoid costly mistakes, delays, and rework, as well as improve your reliability and efficiency.
Finally, to improve your BOM and variant costs, you should start your BOM early in the product development process and update it regularly. Additionally, use a standard format and structure for your BOMs and variants, assign clear roles and responsibilities for your BOM stakeholders, document and communicate any changes or revisions to your BOMs, and review and audit your BOMs periodically. By following these best practices, you can ensure the accuracy, completeness, and consistency of your BOMs while also enhancing collaboration and coordination.

I'm reading this before I start the generation of a BOM template ready for goods we are set to manufacture at the start of 2024. Too early? Consider:- Tools take 42 weeks to manufacture and make first samples. I can keep track of material size development along the way and ultimately have a working BOM when the time comes for production. ?? I will then generate parts in the system and upload my BOM's to the system (More than 200 parts warrants an upload to me. ?? Else manual input!)

Well first off engineering should be in charge of releasing BOMS and all changes to the BOM including deleting it. But they should alert purchasing and sales of the hold on the particular BOM involved so as to reduce shortages of product inventory.
-
We have a multi disciplined team during the start of all projects. BOM changes are discussed with all teams and they must decide how each change affects them. Ongoing production:- We go as far as having check sheets in engineering change meetings. A list of questions for each discipline to ask of themselves for any given change. Ultimately we are all responsible for the BOM, and associated data, being accurate.
