Final answer:
The objective of 'Fit with Strategy' in performance management is to ensure the system's alignment with the organization's strategy, demonstrated through a well-documented mathematical model and an evaluation process that is straightforward and practical for managers to implement.
Step-by-step explanation:
The purpose of fitting with Strategy as an objective of a performance management system is to ensure that the system aligns with the overall strategy of the organization. This involves creating a mathematical model that shows the effectiveness of the design in meeting client needs and demonstrates the basis for performance. It is essential not only to design a performance management system that supports the strategy but also to make the evaluation process simple and do able. This means that the evaluation system should be easily understandable for program managers, clearly outlining the activities being measured (what is being done) and the reasons for these activities (why is it being done), thereby ensuring its usefulness and usability. Careful planning of all aspects of the evaluation ensures that inevitable changes can be incorporated with ease.
