We have proven capabilities in collecting data through call-centre, field-work and focus group facilities and web interviews platforms. In ensuring the highest quality data we follow a 6 fold approach as described below:

1. Design & pilot the data collection instruments

Instruments are designed based on internationally agreed protocols. In order to validate the instruments these are piloted in non-survey sample area to capture the local context and ensure internal validity

2. Set up the data collection protocols

Necessary protocols include:

  • Sample selection

  • Drop criteria

  • Replacement strategy in case respondent cannot be reached

  • Set system for reporting drops and replacement logbook

  • Define target respondent

The manual provides the basis for the enumerator training. The manual contains information about:
