Finite soluble groups satisfying the replacement property

We investigate the finite soluble groups $G$ with the following property (replacement property): for every irredundant generating set $\{g_1,\dots ,g_m\}$ of maximal size and for any $1\mathrm{\ne }g\in G$ there exists an $i\in \{1,\dots ,m\}$ so that $\langle g_1,\dots,g_{i-1},g,g_{i+1},\dots,g_m\rangle=G.$
