Not-Linear BOM Perspectives

September 2, 2010

Summer is finally over. This is a good reason to stop talking about fancy social software and cool Apple’s features. Let’s move back to the core of design, engineering and manufacturing. Yes, I’d like to talk about Bill of Materials. The following blog article drove my attention earlier this week – BOM: An ENOVIA V6 Perspective. Vik Paranjpe of Razorleaf is discussing details about V6 BOM specifics. I found his initial passage very interesting:

By now companies have accepted the reality that product creation is not a linear task going from Design department to manufacturing and beyond. All the departments (including Design, Development, Quality, and Manufacturing) provide input to the product development process, e.g. Quality might have an opinion on the types of components to be used which in turn will impact the design being produced. This increases the need for a centralized BOM management solution that provides a single source of truth for the bill of materials with different “views” of the BOM for each department.

What I specially like is a definition of product creation as “not linear task“. It fits my perspective on the need to consolidate Bill of Material management effort. My last take on this was about a year ago in my post – Seven Rules Towards Single Bill of Materials. Since then, I had a chance to discuss a concept of Bill of Material consolidation with customers and experts. I think, companies need to make an effort in consolidating their Bill of Materials related tasks. However, the software available today on the market contains multiple gaps that can make implementation very complicated.

Single BOM vs. Multiple BOMs
This is one of the key questions people is asking when trying to analyze the capability of BOM Tools. In my view, this question is very misleading. The real question should be related to the ability of software to handle the complexity of tasks related to product structure modeling for all users in the organization. Designers, Engineers, Manufacturing planners and all other relevant people need to have an ability to access the product structure and BOM Information.

Automatic vs. Manual
I can see a “not-linear” product creation as the ability of Bill of Material tools to handle multiple synchronization and change steps related to performing various tasks in design, engineering and manufacturing planning. BOM provides you with the ability to consolidate it. One of the usual mistakes is trying to provide a fully automated process of Bill Material synchronization rules. The appropriated balance of automatic and manual tasks is absolutely important to make BOM tool fit the needs.

BOM Tools – Devil in Details
In order to perform BOM-related tasks successfully, BOM software needs to provide a diverse set of tools. The granularity of these tools is a key, in my view. You need to be able to perform a variety of BOM slice&dice, changes and reviews. The usability and availability of rich set of functions is the key.

What is my conclusion? Despite a long history, Bill of Material management is a still very challenging task. PDM/PLM vendors are working for decades to provide improved software modules to satisfy user demands. Each time, we see new modules and approaches in Bill of Material management. Lately, I can see a trend to provide better vertical integration in PLM tools. BOM management is a central part of this vertical integration. However, implementation of complex PLM suites is an expensive task. A good question could be what is the potential alternative of vertical integration?

Seven Rules Towards Single Bill of Material

October 14, 2009

I’d like to continue discussion around the topic raised yesterday by Jim Brown and this is about “single bill of material”. I was reading Jim’s post and my thoughts was about why managing of single bill of material is questionable? I think the key answer to that is because in a real company we have multiple systems and everybody are touching bill of material. So, since I hardly believe business owners of these systems will agree how to share Bill of Material, we do have a “multiple bill of material” status-quo.


Now, I don’t believe systems like we have in manufacturing companies – all these EDM, PDM, PLM, ERP, CRM, MDM… will be magically agree on how to share bill of material in short term. But at the same time, I think, our industry is spending mega-bucks trying to synchronize all these bill of whatever we have (materials, documents, processes, requirements, configurations etc.). So, since Daily PLM Think Tank is about ideas, I decided to put key seven rules that can bring us to the new status quo of “single bill of material”. May be definition of this bill of material in the beginning will be shared between multiple systems, but even so, it will create movement toward single bill of material.

So, here are my seven rules.

1. Complete Data Representation. Data in Bill of Material starting from Part Number and ending all characteristics need to be complete to satisfy needs on all “company-customers” in every department starting from sales and ending up in manufacturing and services.

2. Unique Part Numbers. We need to establish a central system to maintain by single system. If Part is going to change from Form Fit and Function standpoint, new unique Part Number need to be created.

3. Synchronized Changes. We need to prevent changes that potential can be made on partial data representation. Example could be changes in Design System without appropriated changes in manufacturing and all other systems or data collections.

4. To use Part Numbers only.
Bill of Materials need to be made of Part Numbers only. We need to prevent usage of any alternative identification such as – drawing numbers etc.

5. Include all scheduled items. We need to include all items that need to scheduled for manufacturing and shop-flow. Everything that going to production need to be incuded into bill. There is no item that will be excluded for whatever reason (i.e. non completed assemblies and semi-finished items).

6. Less levels will be better.
The simple solution is the most complicated one. Today manufacturing is struggling to become lean. I think to manage as less as possible levels in Bill of Material will allow to simplify significantly everything we are doing (including way to synchronize or management bill of material).

7. Complete Approval before change. All requested to change need to be approved by all people that are using Bill of Material before bill is going to change. This is will allows trust between users of the bill of materials.

So, in my view, by following such rules we can get much better quality Bill of Material in organization. This is not requires religious discussions about single vs. multiple bill of materials. In the end, nobody cares in how many databases/files/servers we are going to store this (or these) bill of materials.

As usual, I’m very interesting in your feedback. Especially on such non-technological topic. Please, let me know what do you think?

Best, Oleg


SolidWorks World 2009 is Ready for PLM!

February 5, 2009

SolidWorks World 2009 in coming to Orlando next week and I’m preparing to blog about this. And, yes… I’d like to start a discussion about how the SolidWorks community is ready for PLM. Compared to many SolidWorks visualization tools, many customers find PLM and anything to do with data management just plain booooring… But if you take another minute and think about it a bit more, you might think differently… We are in an economical downturn. This is a perfect time to show some additional areas of focus rather than concentrating only on the newest and latest set of SolidWorks features. That’ s not to say that features aren’t interesting – I am sure they are all great and will be perfectly delivered by my colleagues from DS SolidWorks Corp.  What I am saying is that this is an opportunity to leave features alone for a bit, and speak more about PLM.

 PLM can help you practically to get better control over the cost of the products you design and manufacture. I’m sure that you know that 80% of the product cost is defined during the design phase. You can establish the right environment in which you control design, engineering and manufacturing information at the same time in the PLM system. This is possible by supporting Item Masters and multiple Bill of Materials. As soon as you will be able to produce an engineering and manufacturing BOM, and visually compare and synchronize changes, you will be able to optimize your product cost during the design time, since you will already be taking manufacturing and supply chain information into consideration.

 Imagine that you can access the engineering and manufacturing Bill of Materials directly from your SolidWorks environment, collaborate together with manufacturing planning engineers on the same Bill of Material structure, and optimize your changes together. PLM tools will allow you to work in cycles together with your engineering and manufacturing colleagues. At the end of the design phase, you will have a “ready for production” Bill of Materials. You will be able to get rid of all the excel spreadsheets you are using today to produce multiple Bill of Materials. These will be replaced with tools integrated into SolidWorks. You can see some examples of SmarTeam PLM interfaces with SolidWorks bellow.

 I hope this has sparked your. I will keep blogging on these topics during the next week, live from SolidWorks World, and look forward to seeing you all next week in Orlando. Let’s keep our fingers crossed for good weather (compared to what I’ve been experiencing lately in Boston, Mass :) ).

 Oleg.
