Editing Performance appraisal (section)

===Objective production===

The objective production method consists of direct, but limited, measures such as sales figures, production numbers, the electronic performance monitoring of data entry workers, etc.{{sfn|Howes|Muchinsky|2022|p={{page needed|date=September 2024}}}} The measures used to appraise performance would depend on the job and its duties. Although these measures deal with unambiguous criteria, they are usually incomplete because of criterion contamination and criterion deficiency. Criterion contamination refers to the part of the actual criteria that is unrelated to the conceptual criteria.{{sfn|Howes|Muchinsky|2022|p={{page needed|date=September 2024}}}} In other words, the variability in performance can be due to factors outside of the employee's control.  Criterion deficiency refers to the part of the conceptual criteria that is not measured by the actual criteria.{{sfn|Howes|Muchinsky|2022|p={{page needed|date=September 2024}}}} In other words, the quantity of production does not necessarily indicate the quality of the products. Both types of criterion inadequacies result in reduced [[Validity (logic)|validity]] of the measure.{{sfn|Howes|Muchinsky|2022|p={{page needed|date=September 2024}}}} Regardless of the fact that objective production data is not a complete reflection upon job performance, such data is relevant to job performance.

====Happy-productive worker hypothesis====

The happy-productive worker hypothesis states that the happiest workers are the most productive performers, and the most productive performers are the happiest workers.<ref name="Staw">{{cite journal |last1=Staw |first1=Barry M. |title=Organizational Psychology and the Pursuit of the Happy/Productive Worker |journal=California Management Review |date=July 1986 |volume=28 |issue=4 |pages=40–53 |doi=10.2307/41165214 |jstor=41165214 }}</ref> Yet, after decades of research, the relationship between [[job satisfaction]] and job performance produces only a weak positive correlation.
