First I will understand the problem and see how it aligns with my company's mission and identity. Next, research if there is an existing solution and more about the competition. Brainstorm with your business and engineering partners about the viability of the opportunity. If it is prospective opportunity, engage with the customer to understand the problem and capture the requirements. Work on the feature set, UX, wireframes, acceptance criteria, milestones, and the launch window. Work with the engineering to execute and deploy an MVP. Launch the MVP and validate the customer interest and your opportunity hypothesis. Understand the metrics, refine and repeat.
