Supervision & Quality Control


Although all Data Collectors were familiar with all the tools, individual Data Collectors were asked to specialise themselves in one or two data collection activities.


Supervision and Quality Control were carried out in the field; peer analysis and the checking of work and work sheets by the Supervisor and Coordinator. The second quality check took place during the data entry phase by the Database Developer and the Data Entry Clerks.


In addition to the internal quality control, the overall approach and work method and efficiency were evaluated, using participant observation techniques, by interns from the University of Trier (Faculty of Geography/Geosciences). So far the MajiData team received the support from nine (9) interns who after their field work presented their findings to the team during an internal workshop.
