Part (a)

Staffing is important, because an organization requires talented workers to grow and prosper. Some organizations are more labor intensive than others, but staffing is important, regardless of the size of the workforce.

Parts (b) and (c)

Staffing is the responsibility of human resources (from a recruitment standpoint) and the various functional areas of the company (from an actual employment selection and training standpoint). Human resources is responsible for getting talented candidates into the pipeline and performing an initial screening process based on basic expectations. However, the hiring managers are responsible for making the actual employment decisions.

Part (d)

In order to recruit and maintain quality personnel, managers can adapt to changes in the external environment (shrinking work force, impacts of technology, etc.) by adopting more insightful interview processes and implementing more robust onboarding, training, and engagement-oriented programs.
