Study Notes
Estimation Life Cycle
The estimation life cycle refers to the process of estimating the effort, cost, and duration of a project or software development cycle. It involves a series of activities that help to refine and improve the accuracy of estimates throughout the project lifecycle.
Phases of Estimation Life Cycle
- Initial Estimation: Rough estimates are provided based on initial project requirements and high-level understanding of the project scope.
- Detailed Estimation: More accurate estimates are developed based on detailed project requirements, breakdown of tasks, and resource allocation.
- Refined Estimation: Estimates are refined and updated as more information becomes available, and the project scope is better understood.
Activities Involved in Estimation Life Cycle
- Problem Definition: Define the problem or opportunity that the project aims to address.
- Requirements Gathering: Collect and document project requirements from stakeholders.
- Work Breakdown Structure (WBS): Break down the project into smaller, manageable tasks.
- Estimation Techniques: Apply estimation techniques such as Analogous, Parametric, and Three-Point Estimation to arrive at estimates.
- Resource Allocation: Identify and allocate resources (e.g., personnel, equipment, materials) to tasks.
- Scheduling: Create a project schedule based on estimated task durations and resource availability.
- Risk Analysis: Identify and assess risks that could impact project estimates.
- Estimate Refining: Refine and update estimates as more information becomes available.
Benefits of Estimation Life Cycle
- Improved Accuracy: Refining estimates throughout the project lifecycle leads to more accurate predictions of project effort, cost, and duration.
- Better Resource Allocation: Accurate estimates enable effective resource allocation and utilization.
- Enhanced Stakeholder Management: Regular updates on project estimates help manage stakeholder expectations.
- Risk Management: Identifying and assessing risks helps to mitigate their impact on project estimates.
