In this lecture, we'll talk about a critical accountability of all PMs: defining your product's strategy. We will define strategy as part of a broader "business motivation" as defined in the Object Management Group's Business Motivation Model. You should first define the "ends" you would like to achieve, i.e., how you'll measure the success of your product, and then define how you'll get there. You can read more about the Business Motivation Model in the OMG spec: https://www.omg.org/spec/BMM/About-BMM/
