C.16.IR:8 - Common Anti-Patterns and How to Avoid Them

Failure in the worked situation	Consequence	Repair
Use the displayed number as the sought value	Loading or clipping changes the answer.	Interpret the reading through the available relation and target conditions.
Select one root and discard the rest	A sign or other consequential branch disappears.	Test the admitted domain and retain every branch relevant to the conclusion.
Demand every parameter’s unique value	Work continues after the requested quantity is determined.	Test agreement on the sought value, as in the zero-voltage case.
Treat a wide computational enclosure as realized ambiguity	Approximation slack is mistaken for attainable alternatives.	Construct feasible witnesses or report the unresolved computation.
Combine readings without their shared-subject condition	An apparent extra equation relates different unknowns.	Recover the time, initialization and subject correspondence before intersection.
Convert repeated readings into a narrower bound by counting them	A common bias or unrestricted bounded error survives repetition.	Supply the error relation that justifies the proposed reduction.
