  1. Incorporating Agile Methods into the Development ofLarge-Scale Systems 資工四 995002042 曾珮綺

  2. Waterfall Method • waterfall method is a sequential design process in which each stage is completed before proceeding to the next one. • five phases: • requirements specication • design, • implementation or coding • testing and debugging • maintenance

  3. Agile Development • Agile Manifesto: • 1.Individuals and interactions over processes and tools • 2. Working software over comprehensive documentation • 3. Customer collaboration over contract negotiation • 4. Responding to change over following a plan

  4. Waterfall V.S.ExtremeProgramming

  5. CHALLENGES OF LARGE-SCALE XP • Spatial Challenges • Different buildings, or countries • Temporal Challenges • Different time zones • Cultural Challenges • language barriers, cultural references, and customs

  6. HYBRID AGILE METHODS • One can consider adopting a more hybrid method that attempts to use the best of both waterfall and XP-like practices. • A large-scale project may need comprehensive documentation for reasons such as: lack of communication among developers, personnel turnover, and the use of third-party maintenance organizations. • large-scale projects tend to have a larger code base and lengthy development cycles, making code refactoring time consuming and costly

  7. Soundararajan's • Soft-Structured Agile Framework • Agile Requirement Generation Model (Agile RGM) • Development Process • objective is to accommodate change in both large-scale or small-scale projects

  8. Agile RGM • Education • Feature Development • Story • Development Process • For small-scale systems, the development team may follow an iterative structure like XP • For large-scale systems, the development team may require a more structured approach and can choose to follow a more conventional waterfall-like approach.

  9. PHASING INTO LARGE-SCALE AGILEPROCESSES
