  2. Overview • Cost Estimation • using COCOMO • Schedule Tracking • using a GANTT Chart • Milestones Completion • using a PERT Chart • Process Report • Specification Analysis • Management Report

  3. Cost Estimation : COCOMO • Constructive Cost Model (COCOMO) Ei = a * (KDSI) b • Ei : Nominal Development Effort Estimate in man-months • a, b : constants • KDSI : Delivered Source Instructions in Thousands • Estimate of lines of source code : 800 (0.8K) • COCOMO Software Development Mode : Organic • Variables : a – 3.2, b – 1.05 Nominal Development Effort = 3.2 * (0.8)1.05 = 2.53
