The project plans should be adaptable and account for potential changes and uncertainties. The government should allocate resources efficiently and ensure proper budget control to prevent financial overruns. Also, resource utilization should be monitored to optimize cost-effectiveness while maintaining project quality.enProject PlanningStakeholder ParticipationResource AllocationLeadership MonitoringArticle
