Process Performance Target Cost is another crucial performance target within PRINCE2. It emphasizes effective financial management throughout the project lifecycle.  PRINCE2 advocates for clear cost baselines, regular budget monitoring, and controlled expenditure. Techniques like cost breakdown structures, detailed estimates, and justification of change requests all contribute to responsible cost management.  By adhering to the budget and proactively managing deviations, project managers can deliver results within the financial constraints, ensuring efficient resource utilization and project sustainability.
