Hi,
In my opinion, to understand an individual employee's strengths and weaknesses, you first need to create a friendly atmosphere while maintaining certain boundaries. Communicate with them in a way that helps you understand their goals and the obstacles they face in achieving them. It is crucial that when discussing their specific goals, you ensure that their individual goals are aligned with the organization's goals. For example, an employee may express a desire for a senior position, but it's important to evaluate whether this aligns with the organization's needs.
Document all discussions in writing and show your personal commitment by assuring them that you will do your best to support them. While you may not always be able to fulfill every promise, the goal is to establish trust among employees. Once you notice that employees trust you (evidenced by them approaching you for general discussions and grievances), create a list with employees' names, departments, designations, and your comments on their goals (both positive and negative).
Maintain a master sheet containing all these details, which can be useful during individual employee performance evaluations. This sheet can be shared with department heads to discuss expectations for the group or to provide insights on promotion or demotion decisions without revealing employees' identities if necessary.
I hope this advice proves helpful.
Regards,
Deepti
