BSC Video 8: What is PDIA?

1 min read

Problem Driven Iterative Adaptation (PDIA) is an approach we have developed to help escape capability traps. PDIA rests on four core principles:

  • Local Solutions for Local Problems: Transitioning from promoting solutions (pre-determined by external experts) to allowing the local nomination and articulation of concrete problems to be solved.
  • Pushing Problem Driven Positive Deviance: Creating environments within and across organizations that encourage experimentation and positive deviance, accompanied by enhanced accountability for performance in problem solving.
  • Try, Learn, Iterate, Adapt: Promoting active experiential (and experimental) learning with evidence-driven feedback built into regular management and project decision making, in ways that allow for real-time adaptation.
  • Scale through Diffusion: Engaging champions across sectors and organizations who ensure reforms are viable, legitimate and relevant.

In this video, Lant Pritchett, provides an overview of PDIA core principles: problem solving; authorizing positive deviation; iterating and adapting; and scaling practices through diffusion. We believe that success builds institutions and not vice versa. You can watch the video below or on YouTube.

  1. Recently, I read an article “It’s All About MeE” written by Dr. Lant Pritchett, Dr. Salimah Samji and Dr. Jeffrey Hamme.
    If I understand it correctly, PDIA is a “concept” and MeE is one of the development “tools” which are in compliance with PDIA concept. Am I right?
