Final answer:
The IPO model in industrial psychology involves job analysis as input, training and appraisal as the process, and evaluating employee performance as the output. This model ensures employees are fairly assessed and helps identify areas for development.
Step-by-step explanation:
The Input-Process-Output (IPO) model is used in industrial psychology to assess and enhance performance within organizations. The 'input' stage involves the job analysis and understanding the characteristics necessary for a given role. 'Process' includes the training, development, and performance appraisal systems that match individuals with job requirements and provide feedback on their performance. Finally, 'output' refers to the performance outcomes of employees, which can lead to decisions on promotions, rewards, and further development.
In the context of performance assessment, industrial psychologists apply the IPO model by designing performance-appraisal systems that aim to measure the 'output' of employees fairly and objectively. The goal is to ensure that employees are evaluated in a way that reflects their actual performance and potential for growth within the company, like the example of Imani who passed her probationary period after a structured assessment process.
