This document outlines a framework called the Product Livelog to collect, structure, evaluate, and prioritize product ideas in a transparent way. The framework uses 5 simple questions to build business cases for proposed solutions: 1) What is the problem? 2) Who is the customer? 3) How do we know it's a problem? 4) How big is the opportunity? 5) What is the proposed solution? Answering these questions creates transparency into why certain initiatives are prioritized over others. The framework is meant to make prioritization simple, transparent, inclusive, impactful, and objective.
