Abhinav Yadav, an engineer from BITS Pilani is working with Quality Council of India where he has spearheaded the first on-ground assessment of Swachh Bharat Mission (Swachh Survekshan 2016) for 75 cities across India. He understood the nuances and collaborated with experts to formulate the assessment tool based on inputs, outcomes, and citizen perception parameters. He led a team of 25 associates in office and 200 ground staff for the assessment. He used technology in a cost-effective manner to take feedback from the citizens. The team standardized the definition and declared 1000+ ULBs as ODF. In Swachh Survekshan 2017 Gramin, the same model was used with 650+ districts. He is now planning to leverage the model to Swachh Survekshan Urban across 4041 cities and towns.
