Stajeholder politics /pressure
Each loop in the spiral is split into four sectors.
Objective Setting
Risk Assessment and Reduction
Development and Validation
Planning
what may be the best
development approach if user interface risks are dominant.
throw-away prototyping
If the main identified risk is sub-system integration what is best methodology
waterfall model
If safety risks are the main consideration what is the most appropriate process
development based on
formal transformations
RAD?
(RAD) is a development lifecycle designed to
give much faster development and higher-quality results than those achieved with
the traditional lifecycle. It is designed to take the maximum advantage of
powerful development software that has evolved recently.”
Why RAD?
Traditional development lifecycles, are too slow and
rigid to meet the business demands of today’s
economy
A new methodology must be implemented, one
that allows organizations to build software
applications faster, better, and cheaper.
RAD enables such development.
Advantages of RAD?
1.Provides a more quality
product in less time
2.Ensures greater
customer satisfaction
steps in RAD
- Define the
requirements - Prototype
- Receive
feedback - Finalize software
What is Agile ?
Agile is the ability to create and respond to change.
It is a way of dealing with, and ultimately succeeding in, an uncertain and turbulent environment.
It’s really about thinking through how you can understand what’s going on in the environment that
you’re in today, identify what uncertainty you’re facing, and figure out how you can adapt to that as
you go along
Agile Values?
Individuals and interactions over processes and tools
Working software over comprehensive documentation
Customer collaboration over contract negotiation
Responding to change over following a plan
