Project Monitoring and Control is the fourth stage of the Project Management Life Cycle (PMLC). In this stage, the project team monitors project progress, identifies deviations from the project plan, and takes corrective action to keep the project on track. 

Here are some of the key activities that take place during project monitoring and control:

1. Monitor Project Progress: The project team tracks project progress against the project plan to ensure that the project is on track. This includes measuring actual progress against planned progress, and identifying any deviations. 
2. Monitor Project Risks: The project team monitors potential risks to ensure that they are being managed effectively. This involves tracking the likelihood and impact of each risk, and taking action to mitigate or avoid them. 
3. Control Project Changes: The project team controls changes to the project by assessing their impact on the project and making adjustments to the project plan as needed. 
4. Control Project Quality: The project team ensures that project deliverables continue to meet the required quality standards by implementing the quality management plan. 
5. Control Project Communication: The project team ensures that project information continues to be communicated to stakeholders on an ongoing basis. This includes providing regular progress reports, addressing stakeholder concerns, and managing stakeholder expectations. 
6. Control Project Budget: The project team monitors project spending to ensure that it stays within the project budget. This involves tracking actual expenditures against planned expenditures, and taking corrective action as needed. 
7. Control Project Schedule: The project team monitors project progress against the project schedule to ensure that the project is completed on time. This involves tracking actual progress against planned progress, and taking corrective action as needed. 

Project monitoring and control is a critical stage of the PMLC. It ensures that the project stays on track and that any issues are identified and addressed in a timely manner. By completing the activities in project monitoring and control, the project team can ensure that the project is completed successfully and that project deliverables meet the required quality standards.
