Flag bat thuong	Bat ky chi so nao thay doi > 20% so voi ky truoc → danh dau de dieu tra
De xuat co thoi han	Moi de xuat phai co: lam gi, khi nao, ai lam, do bang gi

Metric phu phiem vs metric hanh dong

Khong phai so nao cung dang dua vao bao cao. Phan loai truoc khi phan tich — bao cao 50 chi so thi khong ai ra duoc quyet dinh nao.
