Industrial organisational psychology can be split into two major focus areas: industrial and organisational. First, there is the industrial side, which involves looking at how to best match individuals to specific job roles. This segment of I-O psychology is also sometimes referred to as personnel psychology.
This includes the assessment of employee characteristics and then matching these individuals to jobs in which they are likely to perform well. Other functions that fall on the industrial side of I-O psychology include training employees, developing job performance standards, and measuring job performance.
The organisational side of psychology is more focused on understanding how organisations affect individual behaviour. Organisational structures, social norms, management styles, and role expectations are all factors that can influence how people behave within an organisation.
By understanding such factors, I-O psychologists hope to improve individual performance and mental health while at the same time benefiting the organisation as a whole.
