Study Notes
Waterfall Model
- Key disadvantage: Limited flexibility – changes in requirements are costly and time-consuming to incorporate, as the process is linear and sequential.
SDLC Phases
- Not included: Deployment and maintenance. While development typically ends with release, it doesn't always end there. Release can occur in phases and maintenance is required to address issues and support software.
Software Process Models
- Necessity for documentation: Waterfall Model - It emphasizes structured documentation and focuses on detailed planning and design.
Team Collaboration
- Dependent Tasks: Waterfall Model - Teams often work in a sequential manner, with one phase building upon the previous. This can lead to delays if one team is waiting for the other to finish.
Rapid Prototyping Model
- Primary characteristic: Early user feedback - It emphasizes creating a working prototype to test and get feedback from users before committing to a full-fledged development effort.
Build-and-Fix Model
- Downside: Lack of proper planning - This model lacks a structured approach, making it challenging to manage complexity, maintain code quality, and address future changes.
Agile Process Models
- Disciplined Approach: Waterfall Model - It has a structured process focusing on well-defined phases, documentation, and reviews, leading to a disciplined and systematic approach to software development.
Agile Process Models
- Feature: Iterative development - Development takes place in short iterations, allowing flexibility and adaptability to incorporate changes and user feedback.
