Design of robust interventions

Some ideas don’t leave you, even if you lose track of them. The idea of robust intervention is one such idea. I first encountered it when I read Nobel laureate economist Joseph Stiglitz talk about it in a 2011 interview. It became my theme of the year in 2011, and I presented my thoughts at TISS, Mumbai, that same year. Last April, I got an opportunity to interact with K V Raghavan Fellow changemakers at Agastya’s Kuppam campus. Here is what I presented on “Designing robust interventions” on April 8, 2026. These are preliminary thoughts, and I hope to build on them. I am aware of the fact that nothing in life is black and white. And classifying interventions into robust vs non-robust is just for understanding purposes.

Joseph Stiglitz's definition of robust intervention: “interventions that are simple enough that you don’t have to very fine-tune to make them work, even if you have a bad president like President Bush.” from Times of India, 2011

Examples of non-robust interventions: The presentation mentions the Iraq intervention by the Bush administration in 2003 and Atal Tinkering Labs (ATL). Iraq war was estimated to last 3-4 months. It lasted 8 years 7 months instead. 457 Atal Tinkering Labs were launched in 2016; now around 10,000 labs nationwide are supposed to be operational. There is no official data on how many are functional. Anecdotal evidence suggests that a significant portion could be either severely under-utilized or non-functional. The centralized NEET exam this year is also a good example of a non-robust intervention. A typical non-robust intervention severely under-performs in achieving its objective, incurs heavy cost-overrun, and leaves most of the stakeholders weaker than when it started, except for a few in power who derive immense benefit.

Examples of robust interventions: Two interventions in India that stand out are Aadhaar authentication and Tihar jail reforms initiated by Kiran Bedi. Aadhaar wanted to create a nationally portable unique identity for people in the remotest parts and marginalized sections of the country. And it succeeded in creating such a system and enrolling people into it. Kiran Bedi started her IG Prisons term with a vision of transforming a jail into an ashram. And initiated ground-up initiatives to gather grievances and systematically address them. She demonstrated how a jail can manufacture goods and run a meditation program. Most of these initiatives are still running twenty years later.

4 characteristics of a robust intervention:

1.       Understanding all stakeholders: Understanding what? Anxieties, aspirations, and biases. And this includes the designers.

2.       Framing based on the crux: Based on the most critical issue that is hindering any movement towards a better state.

3.       Response to crux based on the strength: Is the response based on the resources, skills, and technology that are strengths?

4.       Iterative learning & improvement: Fail fast, learn fast

5.
