A fifth common mistake when assessing interpersonal skills is failing to follow up or to maintain and update the assessment results. Interpersonal skills are not static or fixed, but rather dynamic and evolving, as the person grows, changes, and faces new challenges. For example, someone who had excellent interpersonal skills in the past might lose them over time, due to stress, burnout, or complacency, or someone who had poor interpersonal skills in the past might improve them over time, due to learning, feedback, or experience. Therefore, you should not rely on a one-time or outdated assessment of someone's interpersonal skills, but rather on a continuous and ongoing assessment, that takes into account the current and future needs and expectations of the consulting role. You should also communicate and collaborate with the person regularly, to review their performance, celebrate their successes, and identify their areas for improvement.
