If $E$ is the number of applied states or environmental conditions to consider in a system, the job of the bottom-up analyst is complicated by a cross product factor again $(N-1) \times N \times K \times E$. +If we put some typical very small embedded system numbers into this, say $N=100$, $K=2.5$ and $E=10$ +we have $99 \times 100 \times 2.5 \times 10 = 247500 $. +To look in detail at a quarter of a million test cases is obviously impractical. If we were to consider multiple simultaneous failure modes we have yet another complication cross product.
