Study Notes
Waterfall Methodology
- Sequential process with distinct phases (requirements, design, implementation, testing, deployment, maintenance).
- Inflexible; changes are difficult after a phase is complete.
- Suitable for projects with well-defined, stable requirements and smaller teams with clear roles.
Agile Methodology
- Iterative and incremental development with incremental releases.
- Adaptable to changes throughout the development process.
- Emphasizes customer collaboration and feedback.
- Suitable for projects with evolving or unclear requirements and cross-functional teams.
Scrum Methodology
- An Agile framework with defined roles (Product Owner, Scrum Master, Development Team).
- Work is organized into sprints (typically 2-4 weeks).
- Uses daily stand-up meetings for team alignment.
- Well-suited for complex projects with evolving requirements and high collaboration needs.
Waterfall Advantages
- Well-established methodology.
- Clear requirements and structured approach.
- Proven success and built-in quality control.
Waterfall Disadvantages
- Slow process and inflexible.
- High cost and limited customer involvement.
- Limited innovation.
Agile Advantages
- Flexible and adaptable.
- High customer involvement and continuous delivery.
- Fosters collaboration and early/frequent testing.
Agile Disadvantages
- Lack of predictability and limited documentation.
- Potential time and resource constraints.
- Less emphasis on upfront planning and possible resistance to change.
Waterfall vs. Agile Software Development
- Waterfall: Used for simple software; testing occurs after development; linear structure; less client involvement; limited functionality; fixed development model; lower cost.
- Agile: Used for complex software; concurrent testing and development; iterative structure; high client involvement; full functionality; changeable development model; higher cost.
When Not to Use Agile
- Non-urgent or less complex projects.
- Teams lacking self-organization and professional developers.
- Customers requiring detailed documentation for each development cycle.
- Customers needing approvals at every development stage.
- Customers preferring traditional methodologies.
- Organizations not investing in Agile practices across teams and management.
