Cost effectiveness techniques are a very useful tool for project screening or ranking. Such a screening process ensures that projects that are subjected to a more detailed analysis (including cost benefit analysis) are those that best fit with the objectives of the investment (e.g. poverty alleviation). Section 1 of this note outlines the situations in which cost effectiveness techniques should be used, whilst Section 2 describes the two main types of approaches. Section 3 discusses the issue of economic viability and cost effectiveness whilst Section 4 presents a summary of recommendations.
