Study Notes
Agile Software Development
- Agile software development is an iterative, time-boxed approach to delivering software, allowing for incremental builds instead of all-at-once delivery.
- It addresses issues like project cancellations and failure rates, with statistics indicating that one in every two projects exceeds its budget by 200%.
- Common causes of software project failures include not meeting user needs, rushed deadlines, limited feature delivery, and poor user interfaces.
Traditional Waterfall Method
- The Waterfall model is predicated on assumptions that all requirements can be predicted upfront and phases can be completed before moving to the next.
- It struggles with unrealistic expectations regarding timeframes and budgets, often disregarding valuable user feedback until project end.
- Poor communication at project inception can lead to significant challenges in meeting client requirements later in the process.
Emergence of Agile Methods
- Rapid software development has become critical due to fast-changing business environments, making it hard to establish stable software requirements.
- Agile methods, which gained popularity in the late 1990s, aim to reduce delivery time while allowing software to evolve quickly in response to business needs.
- Dissatisfaction with the overhead of previous software design methods motivated the shift toward agile, focusing more on coding and iterative development rather than extensive design processes.
Agile Manifesto
- The Agile Manifesto emphasizes four core values:
- Individuals and interactions over processes and tools.
- Working software over comprehensive documentation.
- Customer collaboration over contract negotiation.
- Responding to change over following a plan.
- While acknowledging the importance of the right-side items, the focus remains on the left-side items to enhance software development processes.
Agile Principles
- Highest customer satisfaction achieved through early and continuous delivery.
- Working software serves as the primary measure of progress; a key principle throughout agile development.
- Agile practices include consistent reassessment and adaptation throughout the development lifecycle to ensure alignment with user needs.
Advantages and Disadvantages of Agile
- Advantages include faster delivery, increased flexibility, improved user satisfaction, and higher quality products.
- Disadvantages may involve less initial documentation, possible challenges in scalability, and varying levels of experience among team members in applying agile methodologies.
Agile Development Life Cycle
- Involves several stages including concept, inception, iteration, and release.
- Central activities revolve around planning, executing, and reviewing tasks iteratively.
Comparison to Traditional Approaches
- Agile contrasts with plan-driven, traditional methods, which are less adaptable to changing requirements.
- Agile is more suitable for projects where requirement volatility is high, while traditional methods may suit projects with clearly defined requirements.
