Mobile Product Marketing Question:

Product strategy means saying no from time to time. Product managers should prioritize by cherry-picking the project that's likely to generate 80% of the impact and forecast what that impact is, as well as the SWAG cost in resources, money and other scarce resources before they decide to build.

This framework forces a product manager to really think through themes, create a plan, allocate resources, eliminate the need to prioritize different projects against each other, and model/forecast the impact.
