project planning
Project planning is part of project management, which relates to the use of schedules such as Gantt charts to plan and subsequently report progress within the project environment. Project planning can be done manually or by the use of project m ...
. Many processes have been developed to aid engineers in making accurate estimates, such as
*Analogy based estimation
* Compartmentalization (i.e., breakdown of tasks)
