What is the essential difference between GTD and traditional planning and project management?

The three basic objectives of project management are:

1, project scope management

It is a management process to control the work content of the project in order to achieve the goal of the project. It includes the definition, planning and adjustment of the scope.

2. Project time management

It is a series of management processes to ensure that the project is finally completed on time. It includes the definition of specific activities, activity sequencing, time estimation, schedule and time control. Many people introduce GTD time management into it, which greatly improves work efficiency.

3. Project cost management

This is a management process to ensure that the actual costs and expenses of the project do not exceed the budgeted costs and expenses. Including the allocation of resources, the budget of costs and expenses, and the control of expenses.
