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

Relative cost of

correcting error

Barry Boehm

Cost of analysis errors

The cost of correcting analysis errors rises almost exponentiallythe longer they remain undetected.

7/28/2019 Scope of the BA Role.ppt

12/21

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.
