Defining Criteria
You can compare processes of a portfolio based on common criteria associated with the portfolio.
*A criterion is a reference element used to compare initiatives in a portfolio. Criterion values can be predefined.
To view criteria associated with a portfolio:
*Open the Characteristics property page of a portfolio and expand Criteria section.
Example  
To define portfolio criteria, you can:
Use criteria already existing in the repository.
Create new criteria and associated values.
*Criteria are defined from the MetaClass (object type) TaggedValue. Certain dialog boxes use this term rather than Criteria.
