The six-stage Gateway reviews are supposed to be mandatory for high-risk schemes. They are carried out by teams under the auspices of the OGC.
But a National Audit Office report published earlier this month found that government departments were picking which Gateway reviews to commission.
The auditors found that projects were entering the Gateway process late, after the business case had been prepared, and leaving before Gateway 5, which assesses the benefits of systems.
At the hearing of the PAC, John Oughton, chief executive of the OGC, said the strike rate of projects entering the first two stages of Gateway reviews has improved to more than 70%.
He said the OGC is seeking to challenge departments that have failed to carry out Gateway 5 reviews within 12 months of a Gateway 4 review, which looks at whether a project is ready for service. "In a sense we are saying: 'There is no hiding place'," said Oughton.
