Johann van Graan has indicated his determination to overhaul Munster after they lost the Pro14 semi-final to Leinster by the narrowest of margins.
The hosts held off a late rally by the South African's side to win 16-15 at the RDS.
"One point is the biggest and the smallest margin in the world," Van Graan told RTÉ Radio 1's Saturday Sport.
"Bitterly disappointed to come so close and not get it at the end.
"I thought we created a lot of opportunities. If we finished one more, the result could have been different.
"We can improve our execution and I’m looking forward to the pre-season to evolve our game."
The last-four domestic exit adds to Munster's departure at the same stage of the Champions Cup and Van Graan is eagerly anticipating his first full season in charge, having taken over from Rassie Erasmus a third of the way into this campaign.
"We’ve come up short in two semi-finals. It’s so close and yet so far," he said.
"The most important thing is to have a good look at our game, squad and management team and try to take the next step forward.
"I only joined in the middle of November so I’m looking forward to reviewing and reflecting.
"The guys will take some time off from rugby and recover and we’ll start afresh at the end of June."
