A One World Bank Initiative to Drive Development Impact
The future of development holds immense promise—powered by science, driven by data, and grounded in evidence. As we face new opportunities to accelerate progress, the need for smarter, more adaptive approaches has never been stronger.
LEADS — Learn. Adapt. Scale. — is a One World Bank Group initiative that brings this vision to life. Created by the Development Economics Vice Presidency (DEC) and implemented in close collaboration with Regional Vice Presidencies, Verticals, IFC, and other global partners, LEADS equips project teams and government counterparts with the tools, methods, and mindsets to learn in real time, adapt course, and scale what works.
At its heart, LEADS is about closing the gap between intention and impact.
The LEADS Model

LEADS is a structured yet flexible framework anchored in three pillars:
1. Flexible Design
Projects are restructured from rigid blueprints into adaptive, evidence-informed plans:
- Embedding proven solutions from global evidence at entry;
- Building in testable alternatives for future adaptation;
- Enhancing project design to increase expected effectiveness.
2. Science-Based Adaptive Delivery
Implementation integrates scientific learning and A/B testing methods:
- Improving readiness for delivery;
- Reducing implementation delays;
- Increasing impact through trial-and-adopt learning loops.
3. System-Wide Enablers
Impact is scaled by building the institutional infrastructure for adaptive delivery:
- Promoting portfolio-level adoption via AI tools (e.g., ImpactAI), real-time data systems (e.g., MEGA), and embedded field support;
- Supporting governments to build data standards, digital architecture, and supportive legislation to take things to scale.
LEADS Impact Spotlight
LEADS is changing how development is designed and delivered.
· 💰 $280M in efficiency gains identified across 50+ projects ($18B in financing) from LEADS workshops alone in AFE (2024) and AFW (2025).
· ⏱️ 5–6 quarters faster delivery in projects using adaptive, evidence-informed approaches, getting results to the ground faster (see Working Paper).
· 📈 Up to 2x greater impact through trial-and-adopt methods that rigorously test and scale what works (Driving Revolutionary Ideas into Practice).
LEADS isn’t just improving projects—it’s setting a new standard for development delivery.
The LEADS Journey

A New Development Standard
LEADS is helping the World Bank Group become the institution it asks its clients to be: evidence-informed, adaptive, and accountable for results.
By combining DEC’s research leadership with the regional and vertical teams’ delivery muscle, LEADS is turning aspirations into impact—one learning loop at a time.
It’s not just about building better projects.
It’s about building systems that improve themselves.
Building a Culture of Learning
LEADS is more than a framework for project design and delivery—it's a platform for continuous learning across the institution.
To support this, LEADS provides a growing library of toolkits, presentation decks, templates, and curated evidence that feed into the World Bank’s regional Academies and other staff learning initiatives. These materials help project teams, government counterparts, and new staff internalize adaptive methods, apply real-time learning strategies, and integrate scientific tools like A/B testing into their work.
By linking operational teams with cutting-edge knowledge and ready-to-use resources, LEADS strengthens both individual capacity and institutional systems—so learning isn’t just encouraged, it’s embedded.
