Thwaite's strategy will also see the 400 projects in flight at the Met Police reduced to seven big operational change programmes, although some are close to completion and will be finalised.
A major pillar of Thwaite's strategy is to put more mobile technologies into the hands of police officers to make the service more efficient and provide London with a more visible police force on the beat.
"But giving police officers mobile devices sounds easy, but behind the scenes there is a huge amount of architecture and change."
The strategy aims to ensure that 90 per cent of police officer transactions are completed on a mobile device, which he says will provide the equivalent of 900 extra officers on the beat in London.
Arresting the running costs will be one of the largest targets Thwaite's has on his beat.
"I'm looking for run costs versus new development to be 50/50, it would be great to get it lower.
"Public sector procurement is changing with schemes like the GDS [Governmetn Digital Service], so there are more options and there are a lot of things that have come together at the moment," he says.
The Met Police has a large outsourcing agreement with Capgemini at present which comes to an end in December 2015. Thwaite's plans to move to the SIAM operating model adopted by Whitehall departments such as HMRC.
