This textbook is intended to introduce the reader to the various aspects of a software engineering project. I describe the waterfall, exploratory programming, prototyping and other approaches to software engineering. This is followed by modelling to include a brief description of the Unified Modelling Language (UML). Requirements engineering is presented as the starting point of project management. This leads to design, which considers the programming paradigms as well as to the overall system architecture. I briefly cover fault tree analysis as well as Failure Mode and Effects Analysis (FMEA), Failure Modes, Effects and Criticality Analysis (FMECA) and Hazard and Operability (HAZOP). Testing helps to validate and verify the software product. I briefly cover white box and black box testing with emphasis on the procedures during testing. I cover quality assurance to include planning and control. Boehm's COCOMO models provide a good starting point for estimating cost.
