I don't have a formula but I usually start with these steps when I'm also stuckI scan the chart and see where the planets are placed what houses and signs are empty or strong.
I try and find a pattern
Then I check the sun, moon, and Asc, Mc, Ic look at the aspects and see if their characteristics are similar to the placements. (It should be easy since you know the person)
Then I look where the chart ruler is placed to see there direction and motivation in life.
I'll look at the rest of their personal planets
I usually check their 8th house and also see where the ruler of the 8th house is placed and aspected. Maybe I can get an idea of their secrets.
Then there 12th house and is ruler and see if they have any talents I may not know about.
Honestly it depends how much you want to find out and what exactly you want to know, there so many layers.
