Final answer:
Tiffany should support Ralph by reminding him to focus on his sales goals and by offering constructive guidance to help him reach his quarterly quota. Criticism, waiting, or undermining his confidence and responsibilities are not effective management strategies.
Step-by-step explanation:
The best way for Tiffany to help Ralph reach his quarterly sales quota is by reminding him to keep working towards his goal and suggesting strategies to improve his sales without delay. It is not advisable to criticize or belittle him by pointing out he is the worst salesperson on the team, nor is it helpful to wait until after the month is over to take action. Furthermore, suggesting that Ralph rethink his career in sales may be demotivating and counterproductive.
Calling trusted clients on Ralph's behalf could be seen as unethical and might damage the team's dynamics and Ralph's professional development. Instead, Tiffany could provide mentorship and resources or pair Ralph with a more experienced salesperson for guidance. A constructive and supportive approach will foster a positive work environment and encourage Ralph to improve his performance.
