**Question:** Finding the most cost-effective way to do a project

**Core Concept:** Cost-effectiveness analysis and decision-making in project planning

**Why the Correct Answer is Right:**

In the context of project planning, cost-effectiveness analysis (CEA) is a valuable tool that helps in comparing the benefits (effectiveness) against the costs of different options. By evaluating the cost per unit of effect achieved, CEA allows decision-makers to choose the most efficient and valuable approach.

**Why Each Wrong Option is Incorrect:**

A. **Incorrect because it does not focus on comparing costs and benefits:** This option does not address the crucial aspect of comparing costs and benefits, which is essential for making an informed decision.

B. **Incorrect because it only considers costs and ignores benefits:** By only considering the costs, this option overlooks the actual goal of CEA, which is to find the most efficient use of resources.

C. **Incorrect because it focuses on a single criterion (either cost or effectiveness)**: Effectiveness is important, but ignoring the cost aspect leads to potentially inefficient decision-making. A comprehensive cost-effectiveness analysis considers both criteria.

D. **Incorrect because it does not account for long-term implications:** Cost-effectiveness analysis evaluates both short-term and long-term costs and benefits, ensuring a holistic approach to decision-making.

**Clinical Pearl / High-Yield Fact:** Cost-effectiveness analysis is a crucial step in project planning, ensuring efficient resource utilization and optimal decision-making by comparing costs and benefits. It helps stakeholders identify the most valuable use of resources and make informed choices.

**Correct Answer:** C. Cost-effectiveness analysis (CEA)

Cost-effectiveness analysis (CEA) is a valuable approach to project planning that involves comparing the costs and benefits of different options. By evaluating both short-term and long-term costs and effects, CEA helps ensure efficient resource utilization and optimal decision-making. This comprehensive analysis aids stakeholders in identifying the most valuable use of resources and making informed choices.
