The terms "project leader" and "project manager" are often used interchangeably, but they have specific differences. A project leader sets the project's vision and direction, focusing on strategic planning and aligning it with organizational objectives, while a project manager handles day-to-day operations, managing tasks, resources, and timelines for tactical implementation. Project leaders inspire and guide the team, influencing decision-making, while project managers coordinate activities, ensure goal achievement, and excel in resource management. Project leaders have more authority, impacting strategic direction and stakeholder management, while project managers operate within defined boundaries, focusing on successful project delivery.
