Chapter Name: Estimate activity duration
Description:Learners will estimate the amount of time required to complete each activity based on available resources and project constraints. This includes using techniques like expert judgment, analogous estimating, and parametric estimating to calculate realistic timeframes.
Purpuse:To create realistic project schedules and identify potential time-related issues.
Rational:Proper duration estimation ensures that project tasks are completed on time, minimizing delays and preventing disruptions in project timelines.
Chapters Topics
Activity duration estimation concepts and flow of data
Activity Duration Estimation Concepts and Flow of Data: This process involves estimating the number of work periods required to complete individual activities. The flow of data includes inputs like the activity list and resource calendars, tools and techniques such as expert judgment and three-point estimating, leading to outputs like activity duration estimates.
The importance and benefits of estimation of activity duration
Importance and Benefits of Estimation of Activity Duration: Accurate duration estimates are crucial for developing a realistic project schedule. They help in setting expectations, allocating resources efficiently, and identifying potential schedule risks.
Input documents to estimate activity duration (Requirements documentation, Requirements Traceability Matrix, Verified Deliverables, Work Performance Data)
Input Documents to Estimate Activity Duration: Key inputs include the Schedule Management Plan, Activity List, Activity Attributes, Resource Calendars, Project Scope Statement, Risk Register, and Organizational Process Assets. These documents provide the necessary information for duration estimation.
Tools and techniques to estimate activity duration (Inspection, Group decision making)
Tools and Techniques to Estimate Activity Duration: Techniques such as expert judgment, analogous estimating, parametric estimating, three-point estimating, and reserve analysis are used. These methods help in developing more accurate and reliable duration estimates.
Activity duration estimation reports and outputs (Accepted deliverables, Change requests, Work performance information, Project document updates)
Activity Duration Estimation Reports and Outputs: Outputs include Activity Duration Estimates, which specify the estimated time required for each activity, and the Basis of Estimates, which documents the assumptions and methodologies used. Project documents are updated accordingly.
