First, outline all your major achievements and significant contributions since you joined the company. These could be categorized as:
- How you nurtured relationships and enhanced the business.
- Some actions you took that were appreciated by clients, your boss, or colleagues.
- Any additional qualifications you acquired in the last 5 years.
- How you progressed over the past 5 years in terms of learning, taking on more responsibilities, and handling difficult clients or situations.
Next, outline how you can ensure that the company benefits from promoting you:
- How do you propose to take on more responsibilities?
- What plans do you have to contribute more meaningfully when promoted?
- Do you have any plans to upgrade your knowledge or skill sets to improve your professional competence?
- What can the company expect from you once you are promoted?
These are just a few pointers. It is up to you to make a compelling case for yourself to be promoted.
Best wishes.
