Driver-based planning methodology is proposed as a solution, emphasizing the use of operational drivers to create financial models that improve decision-making and responsiveness to changes. Alight Planning software is highlighted as a comprehensive solution that facilitates driver-based planning, allowing for more accurate financial planning and analysis through integrated data and automated model management.
