When a new technology or requirement emerges during the final stages of a project, it's important for the project manager to assess the business value impact of this change. This involves understanding how the change could affect the project's objectives, deliverables, and stakeholders. If the impact is significant, the project manager should review the product roadmap to include any necessary changes. This approach ensures that the project remains aligned with its strategic objectives and stakeholder expectations, while also staying adaptable to changes in the market or technology landscape.
