What is a reliable technique for estimating the scope and cost of a software-development project?

Correct option is C

Function Point Analysis (FPA) is a widely used and reliable technique for estimating the scope and cost of a software development project. It evaluates the functional requirements of the software based on its size and complexity, providing a systematic method for measuring software functionality.
Important Key Points:
1. Function Point Analysis: Focuses on the software's functionality, breaking it down into smaller units like inputs, outputs, and user interactions.
2. Cost Estimation: Provides a quantitative measure to estimate the effort and resources required.
3. Standardized Approach: Used globally for consistent project evaluation and cost management.
Knowledge Booster:
· PERT (Program Evaluation and Review Technique): Used for scheduling and managing tasks, not directly for cost estimation.
· GANTT Chart: Visualizes project timelines and dependencies but does not estimate cost or scope.
· Regression: A statistical technique for predicting outcomes but not specific to software project estimation.
· Feature Point Analysis: Similar to FPA but focuses on advanced software metrics, rarely used compared to FPA.
