This competency framework is designed to help you know where your current strengths and weaknesses lie.
There is no perfect way to grow as a Product Manager as we all have varied backgrounds and all work in different organisations so there isn't a perfect 'next thing' to focus on.
Instead - look at the areas with the lowest score that are holding you back in your current organisation or product and think about which would best suit you right now to grow on in your career.
Note: The next time you want to assess yourself, duplicate your last assessment, log the new date for the new assessment and assess.
I would also advise you take this assessment on a monthly basis. That way, you can monitor your progress and improve where necessary.
