Yes, I think you should be direct. Some more things to keep in mind:
- Make sure you gather proof of how you've grown and all your accomplishments. Don't expect your manager or HR to know or keep track of this for you. Even better do this all the time (even when you're not seeing a promotion or raise [1]). Also gather proof that your responsibilities are in line with those of the role you want (ask, look at the job descriptions etc).
- Think of this as a conversation you're going to have with your boss. It's not a Q&A nor is it a confrontation.
- Show empathy for any position the company might be in (if for example the company is going through hard times and can't afford to promote you right now).
- Do NOT threaten to quit if you get a negative response. Instead, make sure to get feedback on how you can improve and make a plan with your boss on how to fulfill any requirements.
- DO update your resume (should be easy if you're tracking those accomplishments) if you get a negative response. Put feelers out, look at some postings. Quietly.
Good luck.
