リスク分析Risk analysis

Learn in the textbookThe Risk Assessment Process

DefinitionRisk analysis (リスク分析) is the step that estimates the likelihood and size of impact of each identified risk to set its risk level (how big the risk is).

ExplanationEstimates can be quantitative, expressed as numbers such as an amount of loss, or qualitative, expressed as grades such as high, medium and low. Another method rates the asset value, threats and vulnerabilities of each asset to work out the size of the risk, and there asset value bears on impact while threats and vulnerabilities bear on likelihood.

AnalogyIt resembles sizing up how dangerous an approaching typhoon is by weighing whether it is likely to make landfall together with how much damage it would do if it did.

Memory hookAnalysis comes from the Greek for loosening something apart. Picture breaking each risk open to see what is inside and how big it is.

DefinitionRisk analysis (リスク分析) identifies in advance the problems that could hinder carrying out the plan, and evaluates how likely each is and how large its impact would be.

ExplanationRisk (リスク) here means something uncertain that has not happened yet but would affect the timeline, cost or quality if it did. Items with a low likelihood but a large impact should not be overlooked, and preparing for them at the planning stage reduces rework after a problem occurs.

AnalogyIt is like planning for a sudden change in weather or an injury before a climb, by setting a turnaround time and packing spare food.

Memory hookOne theory traces risk to a word for the sheer rocks that sailors steered clear of.
