There is no particular age period/stage that is more or less important.

:

Employee are thus no static entities
Age-related changes/factors in cognitive abilities, work motives & personality

Possibility of a pluralism in trajectories of developmental change.

Knowledge, skills, abilities and other factors change in multiple direction overtime

Work systems to be designed to incorporate those changing characteristics of workers across lifespan

ex. Job knowledge can be transfered to all ages employees with Knowledge sharing programs (DeLong, 2004)

Development means a positive ration of age-related gains and losses

Organizations should know age-related decrements in resource play a role in defining long-term success of their employees. Implementing active interventions supporting LT health and well-being of workers of all age

Development systems to translate gained resources and crrued experiences of older employee into long-term strategie (job crafting int.)

Org. place older workers in work roles that better suits their needs and capabilities (mentoring, orga. ambassor-roles)

Core function of dvp is the search and realization of such plasticity and acknowlege of its constraints.

Reflects notion of adaptaility + proactivity.

There are important Person-level variables for successfully navigating dynamic and changing work environments

Dvp an age-conscious approach to job design (hiher skill variety for older workers, lower turn-over intention)
In case of more-or-less rigid structure or routinized jobs: certain proactive work behaviours to maintain LT person-environment fit

Organizations : to recognize certain elements withing the immediate work and organizational context can serve to support or diminish LF sucess outcomes for all ages workers

Managers to be aware of workers' abilities to learn and develop doesn't decrease with age.
Due to age-stereotype and negative FB, OW may have reduced self-efficacy for learning

Design and implement training and dvp programmes taking into account exp. and motives of all-age workers

Embedded in sociocultural conditions. Certain events can influence developmental course of employees (ex: Great Depression for men aging in the middle of 20th century)

Orga: recognize the role of work and life contexts and event can have for shaping behaviors

Individual development results of dalectics and interactions of 3 influences : normative age-graded, history-graded and non-normative

Orga : role of interinvidual differences/ unexpected life and work events. There is a risk of ecological fallacy - inferences are made about individuals based on their age group membership

Dvp can be seen through a lens of multiple scientific disciplines

One perspectice is a partial and incomplete representation of the entire phenomenon. Important age-related outcomes are multiply determined.

Managers : to be aware that age-related processes are simultaneously shaped by a multitude of factors that reside at different conceptual levels
