We have implemented large household and individual level surveys for a number of projects in countries in sub-Saharan Africa. SurveyCTO builds upon the robustness of ODK to allow us to collect complex data without regular access to an internet connection. CTO takes care of server management for you, so you can focus on what's important.
The available functions enable a lot of flexibility to introduce randomization and preloaded data which has enabled us to implement some simple economic experiments on tablets in rural areas, which previously would have required laptops running custom software.
The support is also great, queries are responded to very rapidly which is great when you're operating on tight deadlines. The team is also very open to suggestions for improvements and actively solicits feedback from their users.
One area which could be improved is the survey management options available. While the server does allow for different user types, additional features to assign interviews to specific enumerators and 'send back' problematic cases would be very helpful in managing field operations.
We conduct complex household surveys on a range of topics relating to agriculture in developing countries. Farming requires a lot of complicated inter-related activities, so to get data we want we need precise and reliable survey instruments that we can deploy in areas where internet access, or even electricity are not guaranteed.
Previously we had used paper questionnaires, which are subject to a lot of potential error and require a long period of manual entry before we receive data. With SurveyCTO we are able to impose constraints to ensure a high level of data quality and monitor results as they are completed in the field. Using the software we have been able to give feedback to our field teams while surveys are still ongoing and solve problems that previously would only be identified long after survey completion.
