e-SIGMA is multimodal in the sense that it has the inbuilt capacity and flexibility to incorporate different modes of survey like CAPI, Computer Assisted Telephone Interview (CATI), and Computer Assisted Web Interview (CAWI). Initially e-SIGMA is developed as a CAPI based system, but to continue surveys with restricted movements and personal contacts under recent crises of COVID-19 pandemic, the facility of CATI mode of data collection is being incorporated within its scope.
