MULTIPLE-CHOICE QUESTION Diane is not confident in her ability to meet her sales goals for this month. Considering the sources of self-efficacy, how could her manager increase her self-efficacy for achieving this goal? The manager could really put the pressure on Diane to achieve this sales goal and make sure she understands that her quarterly bonus-or even her job-is at stake. The manager could provide specific feedback on Diane's sales strategies (those that are effective) and encourage her to shadow the top salesperson on the team to learn some new strategies. The manager could stop by Diane's desk and give her a general pep talk, such as "Go get 'em, Diane!" The manager could remind Diane of each of the few times that she has failed to meet her monthly sales goals in the past
