Departments should:

b)  Review the measurement requirements of new PSAs to ensure that all key elements of performance are well-defined and measurable;

c)  Continue to evaluate existing data sources to assess their suitability for PSA monitoring purposes without compromising performance management and accountability by using data sources that do not offer the required validity or precision; and

d)  Ensure that the basis for claiming success is clear and reasonable, taking into account the ability of the data system to measure progress beyond chance or error.
