Career development refers to the process an individual may undergo to evolve their occupational status. It is the process of making decisions for long term learning, to align personal needs of physical or psychological fulfillment with career advancement opportunities. Career Development can also refer to the total encompassment of an individual's work-related experiences, leading up to the occupational role they may hold within an organization. Career development can occur on an individual basis or an organizational level. On an individual basis, career planning encompasses a process in which the individual is self-aware of their personal needs and desires for fulfillment in their personal life, in conjunction with the career they hold. While every person's experiences are unique, this contributes to the different careers that people will acquire over their lifespan. Careers that are long-term commitments throughout an individual's life are referred to as 'steady-state careers'. The person will work towards their retirement with specialized skillsets learned throughout their entire life. For example, somebody would be required to complete a steady process of graduating from medical school and then working in the medical profession until they have retired. Steady-state careers may also be referred to as holding the same occupational role in an organization for an extended period and becoming specialized in the area of expertise. A retail manager who has worked in the sales industry for an extended period of their life would have the knowledge, skills, and attributes regarding managing non-managerial staff and coordinating job tasks to be fulfilled by subordinates. A career that requires new initiatives of growth and responsibility upon accepting new roles can be referred to as 'linear careers,' as every unique opportunity entails a more significant impact of responsibility and decision-making power on an organizational environment. A linear career path involves a vertical movement in the hierarchy of management when one is promoted.
