Unit 2: Basic Software Engineering (BSE)
•Introduction to software engineering
Software engineering is defined as a process of analyzing user requirements and then
designing, building, and testing software application which will satisfy those
requirements.
•Software Processes: waterfall model, evolutionary model, and component based model
Waterfall Model: The waterfall model is a breakdown of project activities into linear
sequential phases, where each phase depends on the deliverables of the previous one
and corresponds to a specialisation of tasks. The approach is typical for certain areas
of engineering design.
Evolutionary model$is a combination of$Iterative$and$ Incremental model$ of software
development life cycle. Delivering your system in a big bang release, delivering it in
incremental process over time is the action done in this model. Some initial
requirements and architecture envisioning need to be done.
Component-Based Process Model
It follows then that a$component-based process model$is a description or template that
fosters the development of a project by identifying and reusing components that already
exist. Components are simple, self-contained, pieces of functionality that you can combine in
any fashion to solve a problem or set of problems.
•Delivery models: incremental delivery, spiral delivery

•Process activities: specification, design/implementation, validation, evolution
