Final answer:
Managers should identify variables that can influence performance to assess if training is needed. Factors such as immediate response to training, testing outcomes, and behavioral measurements can be evaluated.
Step-by-step explanation:
In order to assess if training is needed to address performance problems, managers should identify all the variables that can influence performance. By understanding these variables, managers can determine if the root cause of the performance issues lies in the need for training or if other factors need to be addressed.
For example, a manager may notice a decline in productivity and profits in a department. To assess if training is needed, they would examine various factors such as the immediate response of employees to training efforts, testing at the end of training to evaluate learning outcomes, behavioral measurements of job activities by supervisors, and other relevant results.
By evaluating these variables, managers can make informed decisions about whether training is necessary to improve performance or if other solutions should be implemented.
