Consider a comparable activity that did not have the undesirable consequences. 

Compare the condition containing the undesirable consequences with the reference activity. 

Set down aU known differences whether or not they appear to be relevant. Analyze the differences for their effects in producing the undesirable consequences. This must be done with careful attention to detail, ensuring that obscure and indirect relationships are identified (e.g., a change in color or finish may change the heat transfer parameters and consequently affect system temperature). 

Integrate information into the investigative process relevant to the causes of, or the contributors to, the undesirable consequences.
