If you are weak in one of these attributes or areas, it doesn't mean you will do badly. Recognizing where your strengths and weaknesses are gives you an advantage. If you understand that your preferred style may be a little different than what's needed in a certain leadership role, then you know 1) that you may need to look for a different role or organization, or 2) that you need to work on strengthening that attribute. If you develop your career management plan and complete this step before you're even in the market for a new job, you'll have lots of time for self improvement.
Another benefit to doing this type of self assessment in advance is that it really prepares you for the upcoming job search process. Potential employers are likely to ask about your style and preferences and ask for examples, so you're laying the groundwork to think about these things and to develop sincere and well-thought-out responses. And because you'll be better in touch with your own preferences, as you're talking with potential employers you're going to more easily pick on up whether you truly want the job they're offering you.
It's important to look at your skills and preferences and match those to the kinds of job you're looking for. An honest self assessment will help you decide what company you want to work for, whether the position and the organization's expectations are a great fit (past the paycheck), and will prepare you to interview there when the time comes.
