Risk Log - If statement???

[Elmani]

Hi,

I have created a risk log for which I need a formula to help calculate the overall risk rating.

In Column A, I am listing the Impact (Low, Medium, High) and in Column B, I am listing the likelihood (low, Medium, High).

I need a formula in column see that calculates the overall rating based on the first two columns.

I won't bother listing all of the possible ratings, but have listed a few as an example - if someone could give me the basic formula, I'm sure I can then add in all of the outcomes.



Impact Liklihood Overall Rating
Low Low Low
Medium Low Low
High Low Medium


Thanks in advance....

One way would be to have a 'lookup table' like I have in columns E and F. Then the formula in C2 (copied down) is:
=VLOOKUP(A2&B2,$E$1:$F$10,2,0)

Mr Excel.xls
	A	B	C	D	E	F
1	Impact	Likelihood	Overall		Impact/Liklihood	Overall
2	Medium	Medium	Medium		LowLow	Low
3	High	Low	Medium		LowMedium	Low
4	Low	High	Medium		LowHigh	Medium
5	Medium	High	High		MediumLow	Low
6	Low	Medium	Low		MediumMedium	Medium
7					MediumHigh	High
8					HighLow	Medium
9					HighMedium	High
10					HighHigh	High
11

If I got the combination right, which is:

High Low Medium
High Medium Medium
High High High
Medium Low Low
Medium Medium Medium
Medium High Medium
Low Low Low
Low Medium Low
Low High Medium

you can use this formula:
=IF(A1="High",IF(B1="High","High","Medium"),IF(A1="Medium",IF(B1="Low","Low","Medium"),IF(B1="High","Medium","Low")))
