Why do some apps change the world while others fade away?

Have you ever noticed how some apps become part of our daily lives, while others fade away? A new study has discovered that it's not just a matter of technology, but of the right conditions. Experts analyzed 13 cases of large-scale digital interventions in India and abroad, finding that six key ingredients are needed for success: clear rules, a solid business model, adequate scale, a specific problem to solve, enabling prerequisites, and time. Having open software is not enough; all these elements must work together. Success stories like Aadhaar and UPI show that when these conditions are met, apps can become self-sustaining and change the rules of the game. So, the next time you use an app, think about all the factors that made it so useful!

The study uses crisp-set Qualitative Comparative Analysis (csQCA) to identify the necessary and sufficient conditions for the persistence of digital interventions. Nash equilibrium theory is applied to explain how the realignment of incentives can lead to lasting change. The six key factors identified are: regulatory enablement, credible revenue model, substantial scale, clearly targeted systemic barrier, presence of enabling prerequisites, and sufficient time. These factors, combined, create an incentive-compatible ecosystem, which is crucial for the long-term success of digital interventions.
