Cost-benefit analysis
Estimates the total monetary value, costs and benefits, of a project.
Typically used for public projects such as highways and other public facilities.
Jules Dupuit
Credited with conceiving cost-benefit analysis.
What caused cost-benefit analysis to become common?
The Federal Navigation Act of 1936.
This act required that the U.S. Army Corps of Engineers undertake waterway system projects when the total benefits exceed the costs of the project.
What is one of the biggest challenges in conducting cost-benefit analysis?
Converting the outcomes of projects into a monetary figure.
Cost-benefit analysis requires that all costs and benefits be converted to a monetary value. This means that social and environmental benefits, such as the preservation of open space, have a monetary value.
In a cost-benefit analysis, the costs and benefits must be set for
A particular time and specified location.
In a cost-benefit analysis, the proposed project is compared to what?
The current situation without the project.
In a cost-benefit analysis, the monetary benefits of the project outweigh its monetary costs if…
The ratio of benefit over costs is greater than one.
In comparing multiple alternatives, the largest ratio creates the highest net monetary value.
What is cost-effectiveness analysis?
A method for selecting among competing projects when resources are limited.
This was developed by the military.
For example: if a community has $50,000 to spend on park improvements, then several different projects can be prepared, such as adding playground equipment or purchasing a new lawnmower.
What is the CE ratio?
AKA The cost-effectiveness ratio which can be used to determine which option is the most cost effective.
(cost of new strategy - cost of current practice)/(effect of new strategy - effect of current practice)
What is Net Present Value?
Calculates the net monetary value of a project, discounted to today’s present value.
For example, if the net present value of a proposed hockey arena is greater than zero, then one can conclude that the monetary benefit of the hockey arena outweighs its monetary costs.
What do you need to know to calculate net present value?
The years of the project’s lifespan, the quantified monetary benefits, the monetary costs, and the interest rate.
What is the alternative to net present value?
Internal rate of return
How is internal rate of return different than net present value?
The project’s net present value is at zero and the interest rate is blank.
If the calculation results in an interest rate that is greater than the available market interest rate, then the project would be financially beneficial (side note - unclear if this is specific to internal rate of return or also applies to net present value, make sure to confirm).
What are the major project management techniques?
- Goals Achievement Matrix (GAM)
- Gantt Chart
- Linear programming
- Program Evaluation and Review Technique (PERT)
- Critical Path Method (CPM)
What is the Goals Achievement Matrix (GAM) strategy?
A comprehensive way to evaluate different projects. It consists of a table that lists projects in rows and the evaluation criteria in columns. The matrix lets you score each project against the evaluation criteria and compare them to each other.
What is a Gantt chart?
This chart focuses on the sequence of tasks necessary for project completion. Each task is represented as a single horizontal bar on an X-Y chart. The X-axis is the time scale over which the project will endure. The length of each taskbar corresponds to the duration of each task.
The relationship usually shows dependency, where one task cannot begin until another is completed.
Created by Charles Gantt in 1917
What is linear programming?
A project management method that attempts to find the optimum design solution for a project.
This system takes a set of decision variables, within constraints, and generates an optimum design solution.
What is Program Evaluation and Review Technique (PERT)?
A scheduling method that graphically illustrates the interrelationships of project tasks.
PERT is a good choice when precise time estimates are not available for project tasks.
How was the PERT method created?
The U.S. Navy developed this method in the 1950s and it is now used widely in the defense industry.
What are the steps in the PERT planning process?
- Identify the specific activities and milestones.
- Determine the proper sequence of the activities.
- Construct a network diagram.
- Determine the critical path.
- Update the PERT chart as the project progresses.
