Which method is known as minimum cost or maximum time schedule method?

Correct answer is maximum time. The critical path is the longest duration path through a network diagram and determines the shortest time to complete the project.

What is cost slope in project management?

Cost Slope: The direct cost curve is a curve that can be approximated by a straight line, depending upon the flatness of the curve. The slope of this straight is the cost slope. It is very helpful in the project cost analysis.

What is the normal direct cost of a project?

Direct costs: Examples of direct costs include fixed labor, materials, and equipment. They are typically one-off costs that come from a single department or the project itself. Indirect costs: Examples of indirect costs include utilities and quality control.

Is that time beyond which the activity Cannot be shortened by any amount of increase in resource?

Crash time is that time, beyond which the activity cannot be shortened by any amount of increase in resources.
