Kenya dropped in rankings to the lower cadre following internal wrangles that saw Cricket Kenya federation disbanded and a care-taker committee formed by the then Sports Cabinet Secretary Amina Mohamed.
Despite not punching a ticket to the next year's world cup, Irungu says the qualifiers in Tanzania gave his charges exposure, adding that they have returned to the country with lots of experience.
The tactician says proper structures needed to be put in place to help the boys transition well to the senior national team as they will be overage when the next U19 World Cup Qualifiers are held in 2026.
"We need to establish a Development side, a Kenya U23 team and the Kenya 'A' outfit to be followed in that order before the players are fully absorbed into the senior national team," Irungu stated.
Irungu has also suggested more friendlies and an U19 Cricket League to toughen the boys into their transition to the senior team.
He is grateful that Cricket Kenya and the government was able to take the team to high performance training in Mumbai, India before they departed to Tanzania for the World Cup Qualifiers.
Team captain Vishil Patel echoed Irungu's sentiments saying: "We had a good tournament in Dar, emerging runners up is such a lofty achievement.
"Our spin department was definitely the strongest in the whole tournament, with spinners taking most of the wickets in the team, we had instances of performance with the bat too. We had different Man of the Match winners from the same team, meaning that someone different was ready to step up on every occasion."
He added: "Batting under different conditions was what we picked as a lesson for the team, we also learnt the importance of batting throughout the innings. Having a good and deep batting lineup accompanied with a lethal bowling attack and good fielding skills is key for the next team that will represent Kenya in the next qualifier.
"It was a great experience for us players and we would like to thank the technical staff, the supporters, Tanzania Cricket Association, Cricket Kenya and last but not least the ICC for providing the opportunity for youngsters to show their performance on a world stage."
