To configure a criticality formula in the String Preferences area of the Preferences page, the formula must consist of one of the following:
A number (e.g., 7, 12.4, etc.).
A criticality field, represented by "c" plus the field’s display order. For example, c2 or c4. The field’s display order is set and shown in the Criticality page.
A list of numbers or criticality fields separated by commas, surrounded by brackets. For example, [c4,c3,c2] or [c7,c5,9].
Every number or criticality field (except those in brackets) must be separated by one of the following math operators: *, /, + or -.
The formula requires a space between the numbers and math operators but not between the items in brackets.
The formula is parsed from left to right with numbers or criticality fields alternating with math operators. When a bracketed list is encountered, the list is checked for any value that is not a 0. The first value that is not a 0 is the value that is used in the formula.
The default Incident Potential Criticality formula is c1 * c2 * c3. In this formula, criticality field 1, criticality field 2 and criticality field 3 are multiplied together.
The default Problem Current CIN formula is c1 * c2 * c3 * [c6,c5,c4] * c7. In this formula, criticality field 1, criticality field 2 and criticality field 3 are multiplied together. Next, criticality field 6, then criticality field 5 and then criticality field 4 are checked for 0. The first criticality field that does not contain a 0 is multiplied into the formula and the two other criticality fields are ignored. Finally, the formula is multiplied by criticality field 7.
Note: Time metric formulas are formatted in the same way as criticality formulas, using a “t” placeholder instead of a “c” (i.e., t1, t2, t3, etc.). See Auto-Calculate Time Metric 1, 2 or 3.
