Final answer:
Jenna's task of determining the number of new tellers needed for the bank focuses on factors like growth rate and transaction volumes rather than the bank's marketing strategy, which is generally irrelevant to her immediate hiring analysis.
Step-by-step explanation:
When Jenna is tasked with determining how many new tellers her bank will need to hire over the next five years, she should be focused on variables that directly affect manpower requirements such as the bank's growth rate, customer volume changes, adoption of technology, and changes in business operations or services offered.
The question related to the bank's marketing strategy, however, is irrelevant to her specific task unless the marketing strategy is aimed at expanding the customer base, which indirectly could require more tellers to handle increased transactions. Nonetheless, for her immediate analysis on hiring, factors such as projected transaction volumes, historical staffing patterns, the potential influence of online banking adoption, and turnover rates are far more relevant than the marketing strategy itself.
