basic requirements of taxonomy
Answers
Answer:
Requirements classifications may be compared to a famous one mentioned by Jorge Luis Borges from a Chinese Encyclopedia, Celestial Emporium of Benevolent Knowledge, which divides animals into fourteen categories, whose rationale and purpose have unfortunately been lost.

Requirements as Imaginary Features
As illustrated by this example, taxonomies are symbolic tools that may serve a wide range of purposes, some practical, some speculative, some mythical. Faced with requirements capture, the purpose should be to clarify what is at stake and to identify the nature of subsequent engineering problems to be solved. Hence the search for a comprehensive, reasoned, and unequivocal taxonomy of requirements.
INITIAL OUTCOME
One way to be comprehensive is to start with a preposterous sample and look for some rational, and the Celestial Emporium of Benevolent Knowledge provides such an opportunity to try our hands:
Those that belong to the Emperor: business objectives.
Embalmed ones: mothballed requirements made obsolete by changes in organizational or technical contexts.
Those that are trained: additional requirements to existing applications.
Suckling pigs: additional requirements to projects still under development.
Mermaids: enticing requirements with no clear purpose or stakeholder.
Fabulous ones: ambitious requirements waiting for a technological breakthrough or a dream team.
Stray dogs: requirements with clear purpose but without identified stakeholders.
Those included in the present classification.
Those that tremble as if they were mad: shifting requirements that change when reviewed.
Innumerable ones: growing requirements that multiply when reviewed.
Those drawn with a very fine camel-hair brush: requirements expressed with a graphical modeling language.
Others: requirements that cannot be expressed in terms of symbolic contents.
Those that have just broken a flower vase: requirements associated with recent failures.
Those that from a long way off look like flies: vexing cloud of unclassified requirements that keep coming back and forth.
