Three-point estimating is a technique that can be particularly useful when there is uncertainty about the individual task estimates. It involves the development team providing optimistic, pessimistic, and most likely estimates for each task, which can then be used to calculate an expected duration for the entire project. This method is beneficial when the team lacks experience with similar projects, as it allows for a range of possible outcomes to be considered, which can lead to a more realistic and reliable estimate123.
