Which tools and techniques are used in the estimate activity durations process?
Expert judgment and analogous estimating only
Parametric estimating and project management software
Analogous estimating, three-point estimating, and reserve analysis
Resource leveling and critical path method
The correct answer is: Analogous estimating, three-point estimating, and reserve analysis
Analogous estimating, three-point estimating, and reserve analysis are all used in the estimate activity durations process. Expert judgment and analogous estimating are incorrect because while they may be used in other processes, they are not specifically mentioned in the estimate activity durations process. Parametric estimating and project management software may also be used in other processes, but they are not mentioned as tools specifically used in the estimate activity durations process. Resource leveling and critical path method are also not correct because while they may be used in other processes, they are not listed as tools and techniques used in the estimate activity durations process.
