not setting up the correct preconditions for an algorithm
subject			fact

not setting up the correct preconditions for an algorithm	has definition A common defect in which a program proceeds to do its work even when specifies preconditions, that state what must be true before the algorithm should be executed, are not satisfied
	has testing strategy run test cases in which each precondition is not satisfied - preferably its input values are just beyond what the algorithm can accept
	is a subtopic of 10.3 - Defects in Ordinary Algorithms
	is a kind of defect in an ordinary algorithm
defect	has example the absence of code to handle an exception
problem	has solution which will normally entail developing software, although you may decide that it is better to purchase software or to develop a non-software solution
	should be written as a simple problem statement in one or two sentences
