METHODOLOGIES

Waterfall

Prototyping

Incremental Build Model

Iterative and Incremental Development

Spiral Model

RAD

Cleanroom

-Sequential design

process.

-Progress is seen as

flowing steadily

downwards

-Simulates only a few aspects of, and may be completely different from, the final product.

-Combines the elements of the waterfall model with the iterative philosophy of prototyping.

-Any combination of both iterative design or iterative method and incremental build model for development.

-Intended for large, expensive and complicated projects.

-Advantages of top-down and bottom-up concepts

-Lack of pre-planning generally allows software to be written much faster, and makes it easier to change requirements.

-Embeds software development and testing within a statistical quality control framework.

Agile

Scrum

Lean (Kanban)

Extreme Programming (XP)

DSDM

-Self-organizing, cross-functional teams

-Adaptive planning,

-Evolutionary development and delivery,

-A time-boxed iterative approach,

•rapid and flexible response to change.

-Development team works as an atomic unit

-Opposing to sequential approach

1.Eliminate waste

2.Amplify learning

3.Decide as late as possible

4.Deliver as fast as possible

5.Empower the team

6.Build integrity in

7.See the whole

-Frequent "releases" in short development cycles

-Introduce checkpoints where new customer requirements can be adopted.

-Fixes cost, quality and time at the outset and uses the MoSCoW prioritization of scope.

-Must, Should, Could, Would

Test-driven development (TDD)

-Relies on the repetition of a very short development cycle

Rational Unified Process (RUP)

-Adaptable framework, intended to be tailored by the development organizations

V-model

-Show the relationships between development phases and test phases

Dual Vee Model

-Shows interactions and sequences of developing a complex system and a system of systems.

Feature-driven development (FDD)

-Driven from a client-valued functionality (feature) perspective
