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.
