“A report from right-wing think tank Freer has estimated failed government projects in the last few years have created delays totalling 34 years and wasted an eye-watering £7.5 billion.”

Abridged from the source:

The report calls for reform, suggesting making a permanent secretary fully accountable for delivering projects, even when changing departments, and tying compensation bonuses to project completion. 

Internal  outsourcing from individual departments to a dedicated central unit is on the list as well. So is creating a new government committee to oversee large projects.

The final suggestion called for a deepening of project management and delivery skills.

My comment: instituting a product owner, institutional project sponsors, and internal project development initiative. Right-wing or not, those are sound suggestions.
