2. Soft. Eng. I, Spring 2007Dr Driss Kettani, from I. Sommerville2 Wrap up... What is Software Engineering (SE) ? The major goal of SE is to produce good software cost effectively… What is good software? In order to produce good software, we need to follow a good SE process… What is a good process? Some SE process models are widely used and universally recognized… Software engineering is concerned with theories, methods and tools for professional software development Maintainability, Dependability, Efficiency, Usability Understandable, Visible, Supported, Accepted, Reliable, Rapid, etc. Structured set of activities (steps) required to develop a software system.... The waterfall model Separate and distinct phases of specification and development Prototyping development Specification and development are interleaved Component-based development The system is assembled from existing components

4. Soft. Eng. I, Spring 2007Dr Driss Kettani, from I. Sommerville4 The feasibility study... No matter which SE process we want/expect to follow, we must previously perform a feasibly study in order to demonstrate: The business opportunity; The feasibility of the project in terms of technology enablers and schedule constraints… Our global understanding of the requirements and our confidence in a future better understanding… Must be quick and cheap... Typically in Morocco, it is about 10M/D, 2000-5000Dhs… Depends on the context…
