Stakeholders play crucial roles in technology projects by providing perspectives, resources, and validation throughout development. They can include project sponsors, team members, customers, suppliers, and regulatory authorities. Each stakeholder contributes unique inputs that shape project goals, help identify requirements, and review progress. Engaging stakeholders fosters collaboration, ensuring that diverse interests are considered, which can enhance project outcomes. Additionally, their involvement can expedite acceptance and adoption of the final product, as they can advocate for it within their networks and emphasize its value, ultimately driving project success.
