cmpic Recently i noticed two different discussions. One on LinkedIn in the CMPIC®  Configuration Management Trends group, where Chris Jennings started with the following statement:

Product Lifecycle Management (PLM) vs CM

An interesting debate has started up here about PLM vs CM. Not surprisingly it is revealing a variety of opinions on what each mean. So I’m wondering what sort of reaction I might get from this erudite community if I made a potentially provocative statement like …
“Actually, PLM and CM are one and the same thing” ?

24 days ago

It became a very active discussion and it was interesting to see that some of the respondents saw PLM as the tool to implement CM. Later the discussion moved more towards system engineering, with a focus on requirements management. Of course requirements management is key for CM, you could say CM starts with the capturing of requirements.


There was some discussion about what is the real definition of PLM and this triggered my post. Is the definition of PLM secured in a book – and if so – in which book as historically we have learned that when the truth comes from one book there is discussion

But initially in the early days of the PLM, requirements management was not part of the focus for PLM vendors. Yes, requirements and specifications existed in their terminology but were not fully integrated. They focused more on the ‘middle part’ of the product lifecycle – digital mockup and virtual manufacturing planning. Only a few years later PLM vendors started to address requirements management (and systems engineering) as part of their portfolio – either by acquisitions of products or by adding it natively.

For me it demonstrates that PLM and CM are not the same. CM initially had a wider scope than early PLM systems supported, although in various definitions of PLM you will see that CM is a key component of the PLM practices.

plmbookStill PLM and CM have a lot in common, I wrote about is a year ago in my post: PLM, CM and ALM; not sexy ! and both fighting to get enough management support and investments.  There is in the CMIP group another discussion open with the title: What crazy CM quotes have you heard ? You can easily use these quotes also for the current PLM opinion. Read them (if you have access and have fun)

But the same week another post caught my interest. Oleg’s post about Inforbix and Product Data Management. I am aware that also other vendors are working on concepts to provide end users with data without the effort of data management required.  Alcove9 and Exalead are products with a similar scope and my excuses to all companies not mentioned here.

cm_futureWhat you see it the trend to make PLM more simple by trying to avoid the CM practices that often are considered as “non-value add”, “bureaucracy” and more negative terms. I will be curious to learn how CM practices will be adhered by these “New Generation of PDM” vendors, as I believe you need CM to manage proactively your  products.

What is your opinion about CM and PLM  – can modern PLM change the way CM is done ?
