Deb is a software engineer. She tells her manager, $"$On my performance review, you said you want me to fix bugs in the software faster. If I could get better at fixing bugs, I could get promoted to senior engineer. However, I don't think I can fix bugs any faster. I$\text{'}$m just not that good at it$."$ According to the expectancy theory of motivation, what should Deb's manager do to increase her motivation? Increase her confidence in her ability to fix software bugs, perhaps by providing her with training? or$$Remind her that she will get a promotion to senior engineer if she can raise her performance in this area and that the promotion will come with a big raise? or$$Explore what her career goals are and find out whether there is a reward she would prefer more than a promotion to senior engineer?$$
