Difference between Product Manager, Product Marketing Manager and Program Manager

Product Marketing is external-facing and is responsible for the go-to-market strategy: communicating about the product to the world, providing tools for the sales channels to market and sell the product, online marketing campaigns and basically managing the launch.

Since most of us are familiar with the 4P’s of marketing,
Product – Product Manager
Price – Product Manager/Product Marketing Manager
Place – Product Marketing Manager
Promotion – Product Marketing Manager

Having said that, in some cases a Product Manager may be responsible for all of the above. It depends on the company, the size, the nature of the project etc.

In Micrsoft and hence most companies in Seattle, the folks who define the product and drive the project are called Program Managers, which can initially seem a little confusing because Program Management can also mean multiple Project Management.
