1. G063 – Rapid Application Development

2. Rapid Application Development
What is RAD?
a software development methodology
used by programmers to build working software solutions
aim is to produce a software solution in a short time (< 6 months)
uses minimal planning in favour of rapid prototyping
uses iterative development in the construction of prototypes
the "planning" of software development is occurs during development
“plan as you go”
generally allows software to be written much faster
due to lack of extensive pre-planning

3. Rapid Application Development
How does RAD work?
a team is created - made up of project team + end users
joint application development (JAD) workshops
JAD used to gather user requirements
which should not (but may) change before the end of the project
project requirements are broken down into small ‘chunks’
each ‘chunk’ is allocated a timescale for completion
‘timeboxing’
prototypes of each ‘chunk’ are produced
prototype evaluated against requirements by the JAD
any deficiencies identified are corrected
re-evaluated by JAD
iterative prototyping
build  demonstrate  refine
