An example of rocket science...?
Mars Climate Orbiter went in to orbit at57km above Mars instead of 150km.
It was completely destroyed.
Cause: some navigation calculationsperformed in Imperial units (pound-seconds) and some in metric units (newton-seconds).
Most project failures are due toincom lete/inaccurate re uirements

40-56% of bugs can be traced to requirement errors
Finding and fixing requirement errors consumes 70-85% of project reworkcosts
The average project exceeds its planned time schedule by 120%
52.7% of projects will cost 189% of their original estimate
Only 16.2% of projects will be completed on time & on budget
30% of projects are cancelled before completion.

Inductive VS Deductive Analysis Induction:
a method of reasoning from a part to a whole, fromparticulars to generals, or from the individual to theuniversal.
Example: whenever I let go of a hammer, it falls to theground. Therefore, every time I let go of a hammer it willfall to the ground.
Deduction:
a rigorous proof, or derivation, of one statement (theconclusion) from one or more statements (the premises)i.e., a chain of statements, each of which is either apremise or a consequence of a statement occurring
earlier in the proof.Example: All fairies are pink. Tinkerbelle is a fairy. Therefore,
Tinkerbelle is pink.
Which is better? Thats elementary, Watson.
