Please read the following example carefully t Key result area: Training of new staff- Justification: I recommend the use of a subjective performance measure in order to measure this KRA qualitatively. Specifically, I would employ the behaviour observation scale method to be rated by the manager. This will measure performance in relation to the frequency of observable on-the-job behaviour required to perform this KRA to a satisfactory level (to be pre-determined by the manager). A limitation to this method is the lack of practicality (i.e., utility) and cost effectiveness, because it requires time to analyse, score, and interpret the results of the employee's. It also must be noted that this method may be subject to rater bias. Nevertheless, this is the most appropriate method because it most reliably measures employee performance, with sufficient validity. The use of an objective measure for this KRA. for example time spent training new staff, would be less appropriate because.... Question Based on the above example you need to analysis and discussion Key result area: manager and train staff. t Must meet the following content and requirements, thank you- You need to explain whether this KRA is applicable to subjective performance measurement or objective performance measurement. You need to discuss its advantages and disadvantages, and why another measurement method is not suitable here. About 300 words. Be sure to use your own words. Thank you
