Software Project Scheduling, SQA, Six Sigma & CMM

This unit covers Project Scheduling, explaining its basic principles — compartmentalization, effort validation, interdependency, defined milestones, outcomes, and responsibilities — along with the Work Breakdown Structure (WBS) for dividing projects into manageable components. Project Tracking is explored through the Timeline/Gantt Chart, illustrated with a real 15-day College Management System example. Project Scheduling Techniques are detailed in depth: the Critical Path Method (CPM) for finding the longest task sequence, the Program Evaluation and Review Technique (PERT) for probabilistic time estimation with a book-publishing example, and a full comparison table between PERT and CPM. The notes then shift to quality management, distinguishing Software Quality Control (SQC) from Software Quality Assurance (SQA) across focus, nature, goal, responsibility, and timing. The Phases of SQA — Planning, SQA Activities, Audits, and Reviews — are outlined, followed by Six Sigma Principles using the DMAIC (Define, Measure, Analyze, Improve, Control) and DMADV (Define, Measure, Analyze, Design, Verify) methodologies. Finally, the unit explains CMMI (Capability Maturity Model Integration), covering its Staged and Continuous approaches and all five maturity levels — Initial, Managed, Defined, Quantitatively Managed, and Optimizing — with diagrams.
