About major project delivery
We have significant experience auditing government’s major programmes and projects. These are often large-scale, novel, delivered by multiple stakeholders and present risks many commercial organisations would not take on.
Our work shows the chances of success are closely related to the quality of the early decisions. Common challenges include:
- being realistic about the level of uncertainty around how much programmes and projects might cost and how long they might take;
- establishing robust, yet flexible, governance and assurance; and
- understanding and managing the integration with other projects
No matter the size, these are critical if a programme or project is to deliver value for money. Delay and increased costs on one scheme can have wider repercussions, on other projects, programmes, departments and overall expenditure.
The Government Major Projects Portfolio was established in 2011 to increase transparency and provide independent assurance of the biggest and riskiest projects.
Although this has led to improvements in programme and project management, government could do more to embed good practice.
