Bill of Materials

BOM-data-lifecycle-process

In my recent post about bill of materials – Bill of Materials (BOM): process or technology challenge? I touched the variety of topics related to BOM organization – multiple BOMs and need to manage BOM located in different systems. My main question at the post was around how to make the work with multiple BOMs easier? The problem is tough and the answer is not easy and straightforward. While I was googling the internet to find what others think about this problem, my attention caught TeamCenter PLM blog post – Bill of Material Lifecycle. This posts presents multiple BOMs as a result of changes in the product lifecycle – design, manufacturing, service. Here is a passage I captured:

It is interesting to discuss on BOM lifecycle and its evolution from conceptual stage to full fledge manufactured product to maintenance. In this blog I will explain through life cycle of BOM across the product life cycle done as in house development. The BOM lifecycle can varies based on overall process of company for example some company might only manufacture as order hence they As Build design BOM and they directly CREATE Manufacturing BOM from it.

All together, it made me think that concepts of data, lifecycle and process is often  can create a confusion and overlap. I want to clarify these concepts and present how they can be combined together to manage single BOM in the organization.

1- Data

Data is the most fundamental part of Bill of Materials. It combined from data about product, assemblies, parts and relationships between them. Fundamentally, assemblies and components are connected together to form the result data set representing a product. This data set can be presented in many ways – tabular, hierarchical and many other forms (eg. graph). Data about parts leads us to the place where information about product, assemblies, components, supplies and manufacturers is managed. This information can reside into one of the following systems – CAD, PDM, PLM, ERP, SCM and others.

2- Lifecycle

Lifecycle defines the difference between bill of materials of the same product, but associated with different product development periods (stages). Here is the example of some typical  stages – concept, design, manufacturing, service. However, these stages are not the same for many companies and can reflect industry, specific business practices, regulation and many other aspects. It is very important to capture relationships between Bill of Materials of the same product (assembly) in different lifecycle stages. Missing lifecycle stage connection can cause a lost of very important product lifecycle information and product development traceability. In some regulated industries such

3- Process

Process is a set of activities that defines Bill of Materials data as well as changes in a lifecycle. Sometimes process can be very informal- save of assembly and parts using design system. It will product design BOM data. However, with the complexity of product development and specific organization, some processes are including changes of data, lifecycle stages as well as people involvement. If you think about ECO process, it might change few bill of materials, lifecycle stages as well as product/part information.

What is my conclusion? The problem of bill of materials management must be separated into three distinct problems: 1/ how to create data with BOM? 2/ how to control product dev stages and differentiate the same BOM across the lifecyle; 3/ how to provide tools to manage process and people to work with data and stages. All together, the problem is complicated. However, separated into these pieces it can help you to build a strategy for your BOM management regardless on tools you are going to use. Just my thoughts…

bom-google-add-on

For the last few years, I’ve been chatting about the opportunity to use Google infrastructure and tools to innovate in PLM, engineering and manufacturing.  Google enterprise apps influence on PDM/PLM market is still minor these days. However, I believe, Google cloud infrastructure and tools are consistently inspire established vendors and new companies to develop better solutions.

Earlier last week, I was discussing about how PLM can take over Excel spreadsheets. For long time, PLM tools have love and hate relationships with Excel. MS Office applications are very popular  in every organization for collaboration. Think about SharePoint, Word, Excel. Specially Excel spreadsheet is a king tool in everything that related to BOM management. My old article “My Excel Spreadsheets: From Odes to Woes“ speaks about pains related to the use of Excel for collaboration.

Online tools can solve many problems people are facing when use standalone Excel spreadsheets. Earlier today, Google informed about launching so called “add-on store” for Google Docs and Sheets. Read more here. One of the killing aspects related to Google Sheets Add-on is a transparent way to integrated application user experience within spreadsheet. Watch this video to see more.

Several applications were announced together with Google Sheets Add-on. I selected few of them that can make a lot of sense for engineering collaboration – Project Sheet (from forscale.project) and Workflows (from letterfeed.com). The following passage from TechCrunch article is my favorite:

With the help of add-ons, Google is clearly hoping to create a developer ecosystem around Docs. But maybe more importantly, these integrations will also make it more competitive in a landscape where Microsoft is now finally taking the online versions of its Office productivity suite seriously. For many desktop Office users, the ability to bring add-ons to the desktop versions of Word or Excel remains an important selling point

What is my conclusion? Eco-system or how it is now called “community” is an important element of future success. Microsoft relied on openness of Office and ability to develop add-ins very long time. In a modern world, Google Apps is a good infrastructure foundation for collaboration. It is still not clear if manufacturing companies are ready to trust Google as IT provider for their needs. I believe, a critical mass of application can be one of the factors that can influence future CIO and engineering IT managers decisions. Another obvious alternative is Office 365. Just my thoughts…

bom-process-vs-technology

The importance of Bill of Material in product development and manufacturing hardly can be undervalued. BOM is a cornerstone of almost all processes and activities – from early requirement and design and to manufacturing, services and support. Therefore, efficient BOM management is an absolutely important element of product development processes. PLM vendors are coming with different solutions to manage BOMs. Together with vendors’ solutions, manufacturing companies are developing practices (and sometimes a complete solutions) how to manage Bill of Materials.

I’ve been discussing the idea of “single BOM” for the last few years as a possible way to simplify BOM management. My earlier post – Severn Rules towards Single BOM is almost five years back (2009) raised very interesting debates. All of them are still relevant in my view. I wanted to highlight one very insightful post by Jim Brown here. Jim speaks about different aspects and advantages of single BOM management. As part of this conversation Jim introduced a concept he called – associated BOMs. Here is the passage I specially liked:

Companies have spent a lot of time and effort making logical connections between different BOMs, and developing tools to help develop and synchronize different BOMs. For example, PLM, MPM, and Digital Manufacturing software helps companies translate an engineering BOM into a manufacturing BOM and then further into a BOP. In fact, they have gone further upstream to match conceptual BOMs and requirement structures downstream to BOMs. Maybe you would call these “workarounds” to the real answer of a single BOM. But I would propose a different view based on history and my observations. Perhaps engineers have done what we do best – addressed the problem in the most practical way as opposed to the most elegant way to solve a problem.

I think, Jim’s post is absolutely relevant today. After few years of discussions on this topic, one of my hypothesizes is that companies are not ready for single BOM solution… yet. At the same time, I do believe companies can take realistic steps into single BOM management already today. The variety of ways companies are managing bill of materials can surprise even people with lot of experience in manufacturing and PLM. After many years, I’m always surprised to find “yet another way” to manage bills, configurations and associated manufacturing and production information.

My attention was caught by Teamcenter PLM blog few weeks ago – Bill of Materials concept.  Author, posted a very good summary about different types of BOMs. Together with eBOM, mBOM, sBOM and few others, it outlines the idea of Master BOM as a centerpiece of BOM Management capable to provide “single source of truth” about BOM. The following passage explains the idea:

To overcome this challenge, the concept of Master BOM has come.  Master Bill of Material can be defined as single source of BOM having all aspect of information for various configuration and discipline. Hence Master BOM by definition is single source of truth for all BOM. Industry is still struggling to find the exact solution in term of defining and managing Master BOM. Also it become more complex due to the facts that different BOM types are managed in different systems. PLM vendors including Siemens PLM has come various solution and tools, but still required to show the success and maturity of managing Master BOM as a single source of truth across various BOM lifecycle and discipline.

This post and exchange of comments made me think about potential two challenges in BOM management – technology and process. The way and technology to support and implement the idea of “master BOM” is quite complicated as well as PLM implementation attempts to integrated product data under the umbrella of “single point of truth”. At the same time, the idea of “master” or “single” BOM management faces multiple political challenges including discussions about internal and external company processes. In my view, modern data management technologies (especially coming from web and open source) can introduce some advantages in BOM management. It can be related to scalability of data management solutions as well as improved collaboration features. Would it be enough to overcome process challenges? This is a good question to ask these days.

What is my conclusion? After decades of development in PDM, PLM and ERP, companies are still struggling with BOM management. The topic is quite complicated and introduce many technological and process challenges for companies. Future pressure around competition, customization and cost can bring BOM management challenges back. It will be interesting to see what (technology or processes) improvement will allow to unblock future of BOM management? No specific conclusion. Just thoughts today…

BOM 101: The four pillars of every BOM management solution

January 17, 2013

I suggest you an experiment. Invite two engineers and ask them to provide a definition for some of PDM/PLM related terms. I’d not be surprised if you will get more than two definitions. It is not unusual to spend lots of time during PLM software implementation meetings to define terms, language and meaning of things. […]
