How do research and development expenditures typically change during a product's development?

During the development of a new product, research and development (R&D) expenditures follow a predictable pattern as the project progresses through its lifecycle:

• Early Stages: Expenditures are typically low as the project begins and initial concepts are explored.1
• Peak: Costs increase over time, eventually reaching a maximum as the development effort intensifies.1
• Late Stages: Expenditures decline slowly once the product nears completion and early production challenges are resolved, eventually disappearing as the product establishes itself in a market niche.1

Managing these costs is a critical aspect of research and development, as companies must balance the expense of continued investment against the potential for commercial success and the need to maintain a steady flow of new innovation.1
