A project estimator is working on estimates for a project that is very similar to a previous project, in that it has many of the same features and those features have similar costs. Each feature or deliverable will represent the same percentage of the total cost as it did for the previous project. He is using the $\_\_\_\_\_\_\_\_\_$ method of top$-$down estimating.
