As employed right here, decision frameworks, tools or methods encompass any system utilized to guidance the systematic identification and assessment of data deemed crucial to a call, ranging from checklists to structured problem-diagnostic instruments for example fault trees, event trees or conclusion trees, to computationally supported determination analysis applications.

Cox reviewed the value of separating knowledge plus the interpretation of that knowledge when talking about this new technique.

Kirk carries on the discussion by cautioning the investigator this “sample is going to be altered through the presence of obstructions, or of quickly burned gas in localized places,” and he warns that a very common complication occurs when regions of excellent air flow are current in which “intense burns are going to be observed in this sort of areas that will well distract the investigator from following the fire sample again to its position of origin” (Kirk 1969).
