A Flow Graph of PLM, CRM, SCM and ERP during a Product's Life.
Importance/value on one axis and product life on the other.
Oleg Shilovitsky recently published an article in his blog, Beyond PLM, titled "ERP vs. PLM: More Competition in The Future?"
The article poses good questions and several comments are worth reading. The below graph shows the major Enterprise systems for manufacturing companies in a use/importance FLOW perspective, something like reality, versus the typical, over the wall integration graph shown by many vendors. Oleg asked me to publish it and I hope it adds clarity to the discussion.
The graph is not something ZWS created, I don’t know the author, but I give him/her all credit.
