Risk Matrix Terminology 

It is a term where table used in risk analysis in which rows show the risks and columns show their likelihood (probability) of occurrence and their impact. We learnt in the previous section the process involved in risk. We should analyse the risk in three different terminologies. 

?  Pessimistic: The risk and impact are high and you think you will not be able to meet the expected duration. 

?  Expected:  It is the time structure you originally estimated without worrying about risk. 

?  Optimistic: The risk and impact are low and you think you may be able to overcome the „expected?. 

In the risk matrix, high, medium and low denotes risk rankings. In general high is over 50 percent probability and priority, medium is less than 50percent probability and moderate severity and low is less than 10 percent probability and low impact.

 The risk matrix approaches described in PMBOK and similar sources of risk management information multiply the probability of occurrence of the risk with the impact from the risk to produce a risk index.
