Transcription de la présentation

  1. Software Development methodologies

  2. Methodologies • Waterfall • Prototype model • Incremental • Iterative • V-Model • Spiral • Scrum • Cleanroom • RAD • DSDM • RUP • XP • Agile • Lean • Dual Vee Model • TDD • FDD

  3. Waterfall • Sequential design process • Progress is seen as flowing steadily downwards (like a waterfall) through SDLC

  4. Prototyping • Creating prototypes of software applications i.e. incomplete versions of the software program being developed • A prototype typically simulates only a few aspects of, and may be completely different from, the final product.

  5. Incremental Build Model • The model is designed, implemented and tested incrementally (a little more is added each time). • Finished when satisfies all the requirements. • Combines the elements of the waterfall model with the iterative philosophy of prototyping.

  6. Iterative and Incremental Development • Iterative and incremental development is any combination of both iterative design or iterative method and incremental build model for development.

  7. Incremental vs. Iterative

  8. Scrum

  9. Scrum • Scrum is an iterative and incremental agile software development framework • Aflexible, holistic product development strategy • Development team works as an atomic unit • Opposing to sequential approach

  10. User Story Template – 1 • As a [user role] I want to [goal]so I can [reason] • As a [type of user] I want to [perform some task] so that I can [reach some goal] Example: • As a registered user I want to log inso I can access subscriber-only content

  11. User Story Template – 2 • Who (user role) • What (goal) • Why (reason) • gives clarity as to why a feature is useful • can influence how a feature should function • can give you ideas for other useful features that support the user's goals

  12. Example: Front of Card

  13. Go to Plan • US 1.0 • As an Administrator I want to be able to edit a member’s account so that I can alter their membership details as. • US 2.0 • As an Administrator I want to be able to delete a member’s account so that I can delete members who are no longer a part of the organization. • US 3.0 • As an Administrator I want to be able to email the members of the organization so I can send relevant information only to them.
