Supplementary Slides forSoftware Engineering:A Practitioners Approach, 5/e Chapter 1The Product What is Software? What is Software? software is engineered software doesn’t wear out software is complex software is a ‘differentiator’ software is like an ‘aging factory’ Wear vs. Deterioration The Cost of Change Software Applications system software real-time software business software engineering/scientific software embedded software PC software AI software WebApps (Web applications) Software Poses Challenges Supplementary Slides forSoftware Engineering:A Practitioners Approach, 5/e Chapter 2The Process A Layered Technology A Common Process Framework Umbrella Activities Software project management Formal technical reviews Software quality assurance Software configuration management Document preparation and production Reusability management Measurement Risk management Process as Problem Solving The Process Model:Adaptability the framework activities will always be applied on every project ... BUT the tasks (and degree of rigor) for each activity will vary based on: the type of project (an “entry point” to the model) characteristics of the project common sense judgment; concurrence of the project team The Primary Goal:High Quality The Linear Model Iterative Models The Incremental Model An Evolutionary (Spiral) Model Still Other Process Models Component assembly model—the process to apply when reuse is a development objective Concurrent process model—recognizes that different part of the project will be at different places in the process Formal methods—the process to apply when a mathematical specification is to be developed Cleanroom software engineering—emphasizes error detection before testing Supplementary Slides forSoftware Engineering:A Practitioners Approach, 5/e Chapter 3Project Management The 4 P’s People — the most important element of a successful project Product — the software to be built Process — the set of framework activities and software
