What are the three key factors for successful product development according to the Wall Street Journal?

A business can use its product roadmap to guide its product development process by setting clear goals, nurturing a strong project culture, and maintaining close contact with customers. The roadmap serves as a strategic document that outlines the vision, direction, and progress of a product over time. It helps align the stakeholders and teams towards the business goals and provides a framework for planning and coordination of resources. It also helps in prioritizing features, tracking progress, managing expectations, and communicating plans and updates to the stakeholders.

Some strategies for a successful product launch include creating a clear sense of project goals early in the process, nurturing a strong project culture, and maintaining close contact with customers throughout the process. It's also important to conduct market research, create a strong marketing plan, and ensure that the product meets the needs and expectations of the target audience.
