Study Notes
Agile Methodology
- Agile breaks projects into small incremental builds delivered in iterations lasting one to three weeks.
- Each project in Agile is tailored to meet its unique requirements, contrasting with traditional methods.
- Tasks are divided into time boxes, focusing on delivering specific features for each release.
- Designed by developers, Agile prioritizes customer needs and strong user experience.
- Enhances responsiveness to customer feedback, addressing issues found in older software systems.
- Emphasizes quick software cycles to adapt to changing market conditions.
- Effective team communication is crucial but over-reliance on customer feedback can derail projects.
Iterative Development Model
- Begins with a basic implementation of a limited set of software requirements, enhancing it through repeated iterations.
- Development starts without a complete specification; only part of the software is developed initially.
- Each iteration produces a new software version after reviewing and identifying additional requirements.
- Suitable for large applications, allowing for rapid functionality to meet business needs.
- May risk exceeding scope and using unplanned resources if not managed properly.
- The process generally consists of four phases: planning, risk analysis, engineering, and evaluation.
Rapid Application Development (RAD)
- RAD relies on prototyping and iterative development, minimizing detailed planning beforehand.
- Software development incorporates planning through requirement gathering in workshops or focus groups.
- Early customer testing of prototypes ensures user input shapes the final product.
- Major focus on reuse of existing prototypes and continuous integration for faster delivery.
- Functional modules are developed in parallel; integration occurs to create a complete product.
- Success hinges on the reusability of developed prototypes, and teams are usually small and diverse.
Big Bang Model
- Characterized by little to no structured process; development commences with available resources.
- Software output may not align with customer requirements due to minimal planning.
- Requirements evolve on-the-fly without thorough analysis, often leading to incomplete products.
- Emphasizes flexibility, though often at the cost of structure, organization, and predictability.
Software Development Life Cycle (SDLC) Insights
- Understanding SDLC enhances software quality and improves overall development effectiveness.
- Different models like Agile, Iterative, RAD, and Big Bang are chosen based on project needs and team expertise.
- Key differences exist between models, such as Agile's iterative nature versus Waterfall's linear progression.
Additional SDLC Considerations
- Various software prototyping types exist, focusing on early-stage functional applicability.
- Practices like bug tracking, analytics, and KPI assessments contribute to refining the development cycle.
- Security plans are essential for protecting working code through best practices in all development phases.
