Abstract: An important result of Turull (1984) is the following:

Let $GA$ be a finite solvable group, $G \lhd GA$ and $(\vert G\vert, \vert A\vert) = 1$. Then $f (G) \leq f (C_G (A)) + 2 \ell (A)$, where $f$denotes the Fitting height and $\ell$ denotes the composition length.

The purpose of this work is to give a treatment of the minimal configuration in this framework with additional conditions, yet without the coprimeness condition.
