Explanation:
According to my perspective, training employees is most important to upgrade oneself and in turn promotes organization's growth.
i) For upgrading motivation skill, we can arrange training program or hand-hold one-one, and guide him / her on
Reason: Guidance is enough for leader to achieve things. So it can be achieved through training.
ii) Once again training can change the attitude of the sales manager.
The second option is to speak with the sales manager personally as to what is the result of the manager's action and how this can be achieved.
Session on "attitude", "stress management", "good leadership" will support the manager to change himself.
iii) The person lacks in "finance", so it is necessary to upgrade himself so that he can use his soft skill along with the technical skill and make a successful career and also reach the organizations skill.
Reason: Upgrading technical skill is the mandatory aspect in job.
