Analogous estimating is a project management technique used to estimate the duration or cost of a project based on the metrics of similar past projects. By comparing the current project to previous ones that share similar characteristics, project managers can make informed predictions. This method is particularly useful in the early stages of project planning when detailed information may not be available. This technique relies on historical data and expert judgment, making it a quick and cost-effective way to generate estimates. However, its accuracy can vary depending on the relevance of the past projects used for comparison and the experience of the estimator.
