How Viamo Helped

  • Interviewed 3,800 households
  • Trained 40 supervisors and enumerators
  • Supervisors no longer doing data entry

We developed a computerized survey tool for laptop computers, and designed a survey for more than 3,800 households with more than 200 questions.

Our solution had sophisticated layers of data validation; an ability to identify mistakes instantly and prompt the surveyor to fix them before moving on.
