Paul Downton is determined to implement a greater focus on one-day cricket after England's World Cup exit.
Downton, the England and Wales Cricket Board's Managing Director - England Cricket, described the campaign as "hugely disappointing" after defeat to Bangladesh ended Eoin Morgan's side's hopes of qualifying for the quarter-finals from Pool A.
Downton told ecb.co.uk:"We knew we had a young, inexperienced side but we thought we had quite an exciting side. The fact is we just haven't performed almost in any game and that's really disappointing.
"I think anybody with a realistic view going into this tournament knew we weren't one of the favourites, so let's get that into perspective. But nevertheless we've underperformed, and I feel hugely sorry."
Scores far in excess of 300 have been seen in the tournament, with South Africa posting 400-plus totals against both West Indies and Ireland and Australia a record 417 for six against Afghanistan.
Downton believes that is testament to the influence of Twenty20 cricket on the longer one-day format and spoke of the importance of involving England players in 20-over competition.
"We've tried hard in terms of how we've approached the game and the sort of players we've looked to pick," he said.
"The emergence of Moeen Ali, for example, at the top of the order, we've scored 300 on a couple of occasions, the way we started with Ian Bell when we first went to Australia in the Tri-Series - all of that was very promising but we've not been able to put it together consistently.
"Not many of our players play much T20 cricket, whether it be abroad or at home, and that to me is the biggest lesson out of this tournament - how much T20 is influencing one-day cricket.
"Some of the scores we've been seeing and the way in which people attack throughout the game - you've got to take wickets and you've got to put people under pressure. We've just not been able to do that.
"The first thing we have to do is emphasise one-day cricket a little bit more than we have in the past. You don't want to detract from what we're doing in Test cricket but somehow we have to emphasise one-day cricket more.
"We have to work on developing a stronger feel for the game and that has to start lower down than the professional game."
