I think it is effective the question refers to The House of Mango Street, by Mexican-American writer Sandra Cisneros. The novella tells the story of a girl and how spaces in her house are connected to her memories and her very own identity.
Since one of the intentions of the novella is to show how memories are connected to the character and her spaces, the technique chosen by Cisneros works; it tries to show that memories don't always come in a tight way and they are not usually in order, so vignettes are a suitable technique.
