Project managers and finance professionals need to adopt certain strategies and best practices in order to overcome challenges and achieve the benefits of integration. This includes creating a clear and consistent project charter, scope, and baseline that define the project goals, deliverables, costs, and revenues. It's also important to develop a realistic and flexible project budget and cash flow that reflects the project scope, schedule, resources, and quality. Furthermore, this budget and cash flow should be aligned with organizational financial systems. Regular communication with the finance department is essential for data entry, invoicing, payment, and reconciliation. Additionally, project budget and cash flow should be monitored and controlled with tools such as variance analysis, earned value management, and cash flow forecasting. Whenever there are changes in the project scope or other factors, the budget and cash flow should be updated or revised with a formal change management process. Finally, project budget and cash flow performance should be reported using clear formats like dashboards, graphs, or tables.
