Software Project Management, COCOMO & Risk Analysis

This unit opens with the Management Spectrum (4Ps) — People, Product, Process, and Project — a framework ensuring successful software development by balancing team skills, product objectives, methodology, and project execution. It then covers Software Metrics for Size Estimation, explaining Lines of Code (LOC) and Function Point (FP) as two core techniques for measuring software size and predicting effort. Project Cost Estimation approaches are detailed, including Heuristic Techniques, Empirical Estimation Techniques (Expert Judgement, Delphi Method), and Analytical Estimation Techniques (Halstead's Software Science). A major focus is the COCOMO Model (Constructive Cost Model) — its Basic, Intermediate, and Complete levels, formulas for Effort, Development Time, and Productivity, along with a comparison to the updated COCOMO II model built for modern, reuse-based software development. The unit concludes with Software Risk Management, defining Risk Index, Risk Analysis, and Risk Assessment, and categorizing risks into Technical, Business, Operational, and Programmatic types with their causes. The RMMM (Risk Mitigation, Monitoring, and Management) strategy is explained through its three components: Risk Management planning, Risk Monitoring/tracking, and Risk Mitigation actions.
