Dlamini-Zuma was the first woman elected to the position in 2012.
She was supposed to step down in July last year, but her term was extended by six months after no suitable candidate was identified.
Ghanaian writer Emmanuel Dogbevi says she done well.
“I think she’s done well on the whole. You wouldn’t say she did absolutely excellent, but she did well as a woman.”
But a professor at the University of London, Steven Chen, says she was a complete disaster.
“Whether she is a woman or not, my view is that she was a complete disaster as AU chair. At exactly the moment that Africa needed to rise to the occasion with huge crises, she stepped down.”
Former national human rights chair for Nigeria Chidi Odinkalu agrees.
