The products is designed, implemented, integrated and tested as a series of incremental builds, where a build consists of code pieces from various modules interacting together to provide a specific functional capability and testable as a whole.

Q3. What do you understand by Rational-Man Model? (5 marks)

Rational Man Model

• In a rigorous rational model, it is presumed that the individual is rational enough to accurately rank all the alternatives.
• However, in the real world of humans, specifying all of the alternatives and consequences

is impossible.

• Information systems based on this model need to be based on availability of perfect and complete information on all alternatives so as to ensure certainty.
• Real life situations need to be given room for chances which this model does not provide

for. Rational Man Model – Example

1. In a pharmaceutical drug company, the preparation and testing of life saving drug is a critical phase, and

choice of a perfect alternative is inevitable. Hence the information system devised to support it should be such that it can record and monitor even the slightest variations.

2. In an ammunitions factory, the testing and quality control of various bullet, shells, missiles, bombs, etc is

a sensitive issue. Since chances of error are quite high, the system from selecting and discarding should be with high sensitivity level.

Q4. What are the primary issues to be considered during system development process? (5 marks)

Q5. Practical example of Description Model ( 2 marks )

The Blond Guitar

My most valuable possession is an old, slightly warped blond guitar--the first instrument I taught myself how to play. It's nothing fancy, just a Madeira folk guitar, all scuffed and scratched and finger-printed. At the top is a bramble of copper-wound strings, each one hooked through the eye of a silver tuning key. The strings are stretched down a long, slim neck, its frets tarnished, the wood worn by years of fingers pressing chords and picking notes. The body of the Madeira is shaped like an enormous yellow pear, one that was slightly damaged in shipping. The blond wood has been chipped and gouged to gray, particularly where the pick guard fell off years ago. No, it's not a beautiful instrument, but it still lets me make music, and for that I will always treasure it.
