Study Notes
Waterfall Methodology
- Waterfall methodology is a linear and sequential approach to software development.
- Stages of Waterfall methodology include:
- Requirement Analysis: Gather all possible requirements for the system.
- System Design: Create a blueprint to guide development.
- Implementation/Programming: Actual coding occurs in this phase.
- Integration and Testing: Ensure software meets initial requirements and is defect-free.
- Deployment: Software is moved to the production environment.
- Maintenance: Address and resolve issues that arise post-deployment.
- Advantages:
- Simple and clear structure, making it easy to understand.
- Disadvantages:
- Changes are difficult once a phase is completed due to limited flexibility.
- Best used when:
- Specific, extensive documentation is required.
- Requirements are fixed and unlikely to change.
Agile Methodology
- Agile methodology emphasizes flexibility and customer collaboration throughout the development process.
- Agile Manifesto outlines four core values:
- Working Software over comprehensive documentation.
- Individuals and Interactions over processes and tools.
- Customer Collaboration over contract negotiation.
- Responding to Change over following a plan.
- Key characteristics of Agile include adaptability and continuous delivery of functional software.
- The 12 Agile principles include:
- Early and continuous delivery of useful software.
- Embracing changing requirements even late in development.
- Frequent delivery of work, preferring shorter timescales.
- Daily collaboration between stakeholders and developers.
- Building projects around motivated individuals and trusting them.
- Prioritizing face-to-face communication for effectiveness.
- Progress measured by working software.
- Maintaining a sustainable work pace.
- Continuous attention to technical excellence and simplicity.
- Self-organizing teams yield the best results.
- Regular reflection to improve team effectiveness.
- Benefits of Agile development:
- Enhanced customer focus.
- Increased adaptability to change.
- Collaborative teamwork encourages innovation and productivity.
Types of Agile Methodologies
- Projects may utilize various Agile methodologies such as:
- Scrum
- Kanban
- Lean
