Strategic Sourcing Manager vs. Purchasing Manager

Can someone explain to me if there is a difference between these two positions?

Fundamentally, there is no difference as it is usually more a matter of company philosophy that may determine the title. For example, I have had positions of Purchasing Coordinator, Purchasing Facilitator, Senior Buyer, Manager-Sourcing and Corporate Purchasing Manager in Japanese and US owned companies and in all cases was responsible for Strategic Sourcing, Purchasing, Procurement, Supply Chain Management, etc. Right now I am Corporate Purchasing Manager and my strategic vs tactical tasks vary from week to week.

There is difference between Strategic Sourcing Manager (SSM) & Purchasing Manager (PM).

Normally, the role of SSM is into new product introductions, new vendor developments, whereas PM's role is mostly into procurement of material/compoenents for day to day production requirements.
