CS51  SOFTWARE ENGINEERING
UNIT I
SOFTWARE PRODUCT AND PROCESS
Software engineering paradigm:
•    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
–    characteristics of the project
–    common sense judgment; concurrence of the project team
The software process:
•    A structured set of activities required to develop a software system
–    Specification;
–    Design;
–    Validation;
–    Evolution.
• A  software  process  model  is  an  abstract  representation  of  a  process.  It  presents  a
description of a process from some particular perspective.
