Validity - The intent with which a measurement tool actually measures what it is intended to measure (Gerhart, et al. 2009). Validity also refers to whether the assessment measures all relevant aspects of performance and omits irrelevant aspects of performance (Gerhart, et al. 2009).5. Specific Feedback – Being specific to employees on performance measures helps management strategize to achieve goals. It should always specify what an employee must do to achieve the objectives in order to support the strategy. Goggle's approach to performance management meets these criteria. Goggle analyzes their data to track the performance of managers and employees. They figured out how to analyze all the data to build a profile of the type of manager whose team is most successful (Gerhart et al. 2009). Goggle looks for patterns within the management process to see what types of behaviors produced results. They found that relying on data is a great way to know the results achieved by measuring performance. They also want their managers to let their teams know that they are important to the success of the organization. Goggle has several methods for collecting data to meet performance criteria.
