MODULE I: INTRODUCTION
This module introduces the foundational concepts of software engineering, the evolution of
software development processes, and the models used for software development.
1. The Evolving Role of Software:
Software has grown from simple applications to complex systems that are integral
to business, industry, and personal life. The role of software engineering has
evolved to manage this complexity.
2. The Changing Nature of Software:
Modern software needs to be flexible, scalable, and maintainable, adapting to rapid
technological changes and user needs.
3. Legacy Software:
Legacy systems refer to older software that may still be in use despite being
outdated, often requiring maintenance and reengineering efforts.
4. A Process Framework:
This framework provides structured approaches for developing software
systematically.
5. Process Assessment:
Assessing the maturity and efficiency of development processes to improve
software quality.
6. Personal and Team Process Models:
Models to guide individual and team performance in software development, aiming
for improved productivity and quality.
7. Product and Process:
The relationship between the software product (the outcome) and the development
process (the activities leading to the outcome).
8. Process Models:
Different methodologies or frameworks for software development that guide the
life cycle of a project. This includes:
○ Waterfall Model: A linear, sequential approach to software development.
○ Incremental Process Models: Develop software in small, manageable
increments.
○ RAD Model: A rapid application development model focusing on quick
prototyping.
○ Evolutionary Process Models: Emphasize flexibility and iterative refinement.
○ Prototyping: Developing prototypes early in the development process to
refine requirements.
○ Spiral Model: Combines iterative development with risk management.
○ Concurrent Development Model: Overlapping phases to reduce
time-to-market.
○ Unified Process: A use-case driven, architecture-centric, iterative software
development process.
