Gloucestershire bowler Benny Howell says they were helped by the legacy put in place at the club by former head coach John Bracewell.
Bracewell left the county after being appointed head coach of Ireland in April, but his influence is still felt.
"It's credit to John Bracewell who got all the lads together before he left," Howell told BBC Points West.
"Richard Dawson and Ian Harvey have come in and taken the role and carried it on. It's exciting to be here."
Howell took 3-37 against in their One Day Cup semi-final win over Yorkshire and hailed the depth of their squad for their one-day form.
|Gloucestershire's golden era|
|Between 1999 and 2004, the county won six limited-overs cricket finals at Lord's and won the National League, but their best finish since came when they reached the Twenty20 final in 2007, where they lost to Kent.|
"What is noticeable is that everyone's been involved and chipped in with runs, wickets or brilliant pieces of fielding," Howell added.
But the paceman believes his side have the confidence to get a result in the One Day Cup final against Division Two table-toppers Surrey.
"We always get put as the underdogs and hopefully now we've shown that that is wrong. We are confident that if we go about our business then it could be a good result for us," Howell added.
