CompTIA Project+ (PK0-005)Project Life Cycle PhasesHard
A project manager is in the process of developing the project schedule. After identifying all activities and their logical sequences, the next step is to assign resources and estimate the duration for each activity. Which of the following tools or techniques is MOST appropriate for determining the type and quantity of resources needed for each activity?
- ABottom-Up Estimating
- BActivity Resource Requirements
- CResource Breakdown Structure (RBS)
- DAnalogous Estimating
Show answer & explanationAnswer & explanation
Correct answer: B. Activity Resource Requirements
Activity Resource Requirements (which is an output of the Estimate Activity Resources process) specifically documents the types and quantities of resources required for each activity. While Bottom-Up Estimating (B) is a technique for estimating, Activity Resource Requirements (D) is the *output* that details the specific resources needed per activity, which is what the question is asking for.
Why the other options are wrong
- A. Bottom-Up estimating is a technique where work is estimated at the lowest level of the WBS and then aggregated, but it's a *technique*, not the *output* document detailing specific resource types and quantities.
- C. The Resource Breakdown Structure (RBS) is a hierarchical list of resources by category and type, but it doesn't specify *which* resources are needed for *each particular activity*.
- D. Analogous estimating uses historical data from similar projects for a quick, high-level estimate, not for detailed resource requirements per activity.
Estimate Activity Resources
The process of estimating the type and quantities of material, human resources, equipment, or supplies required to perform each activity.
- Output is Activity Resource Requirements.
- Considers resource availability and skills.
- Feeds into cost and duration estimates.
Memory trick: To estimate activities, you need Activity Resource Requirements.
