As I see it, the real PLM problem or challenge is really not the PLM software implementation project. The real issue is to know what to implement! The concept of PLM is still much fuzzier than f. ex. the area of ERPs.
In my company we discussed for ages about certain details of PLM, its contents and the selecting of the SW vendor. However the real big thing was that there were no clear goals for the whole PLM development project. I think we missed our opportunity here because all the discussions and the definitions of PLM were held in very different levels and everybody had very different understanding of PLM
within our organization.
We all should have read something like this before we launched our PLM initiative in our company. This book really gives you good and clear view into PLM. I recommend!
