Value graph is a brainstorming tool for us to clarifying the goals of a product we are going to deliver and exploring alternate concepts.
It starts with the main product, stretching up to the “WHY” part (the product goals), and stretching down to the “WHAT”(Voice of Customer and Engineering Metrics) and “HOW”(Solution Elements).
We created the following value graph based on our project goal in the early stage, namely a “hardware testing plan” that can reduce hardware testing time and cost.
