PLM And Management Of CAD Files

One of the questions that disturbs me when I’m thinking about PLM is a complexity. In a modern enterprise manufacturing organization, complexity kills. When I’m thinking about the way data management passed since the first introduction in PDM systems, I see a huge amount of blocks built on top of basic PDM functions. In the beginning, PDM was about managing of data records about file. After, additional silos of data were added to represent various aspects of products – Bill of Materials, ECO, Requirements, Projects, Supply, etc. Then we got a mess…  I’d compare it to the situation happened with MRP/ERP industry about 15-20 years ago. Started at the early beginning as MRP and lately a MRP-II, it comes long way to acquire all possible and impossible islands of enterprise data to become, finally, ERP. We are facing a very similar situation these days in PLM.

CAD Files Control Dilemma
For every PLM system, the management of CAD files is a fundamental question that needs to be answered at the early beginning. This is Shakespeare’s “to be or not to be” question of all PLM vendors. Touch CAD files or do not touch CAD files? I see a lot of advantages in management of CAD files: you are getting control on valuable design and engineering information, there is an ability to have a system that has deep and tight connections to the daily life of people in the organization via CAD system operation and many others. On the other side, control of CAD files put a lot of restrictions on users, increase the overall system complexity and in the end create dependencies on vendors of CAD products.

Invisible CAD Data Management
There are two examples I want to talk about in the context of CAD data management: CATIA V6 and Google Apps. Do you see something in common between them? Yes, I do. In both systems, data management and version control are embedded parts of products. You have a built in mechanism to manage version of CAD models as well as Google Apps document. You still need to take care about next version, lock and un-lock operations in CATIA. However, you shouldn’t care about version of your files in Google Apps. The idea I had is a notion of “invisible CAD data management”. It happens, but users should not care about that.

What is my conclusion today? I think, dependencies on CAD were born in the beginning of PDM. We need to revise our technological decisions came from early days on how we can keep control of CAD files and management their revision. The connection between the CAD version management and overall product development (PLM) processes need to become less restrictive and more flexible.

Just my thoughts…
Best, Oleg
