Finance Minister Peter Robinson has taken a sideswipe at politicians on the Public Accounts Committee.
The DUP deputy leader warned MLAs who go for easy headlines could undermine innovation in service.
The MP also hit out at some journalists who fail to take account of the implications of their articles.
In a briefing to business leaders, the East Belfast MP said: "There is an important scrutiny role for the Public Accounts Committee to play, but this must not stifle innovation or on occasion risk-taking.
"Too often elected members have become more interested in easy press coverage for themselves than they have been in better administration in Northern Ireland."
