What I learned this week … is that there are still some technical challenges that make implementing PLM challenging, but that is not what this post is about. The technical challenges include customization, data migration, and integration among others. See Oleg’s post on the “3 main factors of mainstream PLM adoption” for more detail on each of these, and his views on why these three factors impact the adoption rate of PLM. I accept Oleg’s premise on these factors (although we will likely continue to debate the relative priority of ERP integration) from a technical perspective. But I think any technical conversation about PLM implementation has to be complemented with a view on why PLM is really hard – you have to change the way people work in order to improve your product development performance and your product profitability.
