The document discusses various software development process models including: - Common process frameworks that include activities like communication, planning, modeling, construction, and development. - Prescriptive models like the waterfall model, incremental models, and evolutionary process models. - Specialized process models for component-based software engineering, formal methods, and aspect-oriented development. - The unified process which is use case driven and iterative with phases for inception, elaboration, construction, and transition. - Agile process models which value individuals, working software, customer collaboration, and responding to change over processes.

13. The Unified Process
 Use-case driven, architecture centric, iterative, and
incremental software process
 Phases
 Inception phase (customer communication and planning)
 Elaboration phase (communication and modeling)
 Construction phase
 Transition phase (customer delivery and feedback)
 Production phase (software monitoring and support)

15. An Agile View of Process
 Represents a reasonable compromise between conventional software
engineering for certain classes of software and certain types of
software projects
 Can deliver successful systems quickly
 Stresses continuous communication and collaboration among
developers and customers
 Embraces a philosophy that encourages:
 customer satisfaction,
 incremental software delivery,
 small project teams (composed of software engineers and stakeholders),
 informal methods, and
 minimal software engineering work products
 Stress on-time delivery of an operational software increment over
analysis and design
15 IF2036 RPL - IF ITB

16. Manifesto for Agile Software Development
 Proposes that it may be better to value:
 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 the items on the right are still important the items on the left are
more valuable under this philosophy
 Note: although most practitioners agree with this philosophy in theory,
many pragmatic issues surface in the real world that may cause items on
the right to be as important as items on the left
16 IF2036 RPL - IF ITB

17. 12 Principles
 Highest priority: user satisfaction
 Welcome changing requirement
 Deliver working software frequently
 Business people and developers work together daily
 Build around motivated individuals
 Face-to-face conversation
 Working software: primary measure of progress
 Promote sustainable development
 Continuous attention to technical excellence and good design
 Simplicity is essential
 Self-organizing team
 Tune and adjust team behavior at regular intervals
17 IF2036 RPL - IF ITB

18. Agile Process Models
All agile process models conform to the manifesto
and the principles
Examples:
 Extreme Programming (XP)
 Adaptive Software Development (ASD)
 Dynamic Systems Development Method (DSDM)
 Scrum
 Crystal
 Feature Driven Development (FDD)
 Agile Modeling (AM)
