When building a house or constructing an airplane that must be completed by a certain date, which type of scheduling should be used?

A) forward scheduling
B) backward scheduling
C) horizontal scheduling
D) vertical scheduling

Backward scheduling is used when a project has a fixed end date. It involves planning the necessary tasks by starting from the project's deadline and working backwards to determine when work should start. This approach ensures that the project is completed by the specific due date, making it suitable for constructions like houses or airplanes that have a set completion date.
