The Teal Book named HM Treasury Innovation of the Year 2025

The Teal Book, the government’s code of practice for portfolio, programme and project delivery, is HM Treasury’s Innovation of the Year 2025.

Developed by Government Project Delivery, The Teal Book explains how organisations can meet the project delivery functional standard in a way that works in government delivery environments. It turns expectations into practical steps that teams can apply across their environments.

This recognition from HM Treasury follows growing interest from the wider project delivery community in the UK and overseas. The Teal Book’s design, content and structure have established it as a dynamic reference source.

What the award recognises

The Innovation of the Year award recognises The Teal Book for providing:

• a clear, end-to-end explanation of what good project delivery looks like across government
• practical content that supports teams at different levels of maturity
• a single place that connects all guidance across functions that supports government project delivery
• a model for how central guidance can be continually improved based on user feedback

For professionals working in Government Project Delivery, this means it is easier to:

• understand how the functional standard applies to their work
• align local frameworks and tools with cross-government expectations
• access authoritative guidance from a single source

Growing cross-government and international interest

The Teal Book was created with extensive input from departments, arm’s length bodies and across the function and profession.

This collaborative approach is reflected in how it is being used across government, with thousands of users engaging with the guidance, providing feedback and helping to prioritise future improvements.

While The Teal Book was developed for UK central government project delivery teams, its approach and structure are attracting wider attention from:

• other government functions who are exploring how the model could support their own standards and guidance
• overseas public sector organisations, professional bodies and academic institutions have requested demonstrations and case studies
• online project delivery communities have been sharing and discussing The Teal Book, generating interest well beyond its original audience

This external engagement is helping to position the UK’s project delivery function as a reference point for modern public sector practice.

What’s next

The central Government Project Delivery function team is continuing to develop The Teal Book. Feedback from the website and real examples from across government are already influencing the next version. This keeps The Teal Book as a living resource that improves project delivery in government while showcasing UK practice to international partners and suppliers.

As highlighted in the Think Digital Partners feature, the focus now turns to helping organisations adopt The Teal Book at scale and connecting it closely with assurance, capability building and performance measures.

For colleagues who prefer something they can keep on their desk or take into a meeting room, there will be a welcome update soon – designed to complement, not replace, the digital-first service.
