"We will sit together and take stock. We'll take positives from this and discuss mistakes. I'm keen to lead the rebuild," Babar said at the post-match presentation ceremony.
Pakistan couldn't qualify for the semi-finals of the 50-over World Cup for the third consecutive time.
"Yes, very disappointed with the performance. If we had won the South Africa match, it could have been a different story. But yes, have made mistakes in bowling, batting and fielding," Babar summed up his team's campaign where they lost five out of nine games.
Babar admitted that his spinners -- Mohammed Nawaz and Shadab Khan -- not taking wickets in middle overs became crucial.
"We conceded a few too many runs. We bowled a few loose deliveries towards the end. And our spinners' aren't taking wickets, which doesn't help. That has a big effect because you need to take wickets in the middle overs."
