Introduction

Time control is one of the most important responsibilities of a project manager. Every project has deadlines, milestones and deliverables that must be completed within an agreed timeframe. The project manager is responsible for planning, monitoring and controlling the project schedule to ensure work progresses as planned while meeting stakeholder expectations.

Effective time control helps minimise delays, improves the use of resources, supports better decision-making and increases the likelihood of successful project delivery. While the project manager does not complete every project task, they are accountable for ensuring the project team works together to achieve schedule objectives.

This article explains the accountability and authority of project managers in managing project timelines, the tools they use, the challenges they face and the best practices that help keep projects on schedule.

What Is Time Control?

Time control is the ongoing process of monitoring and managing the project schedule to ensure activities are completed according to the approved plan. It involves comparing actual progress against the planned schedule, identifying delays, analysing their causes and taking corrective action when necessary.

Effective time control includes:

• Developing a realistic project schedule 
• Establishing milestones and deadlines 
• Monitoring project progress 
• Tracking schedule performance 
• Managing schedule risks
