Interview simulation: eliminate technical glitches before they disrupt your fieldwork

22 May 2026

Nfield’s Online and CAPI surveys can perform even the most complex tasks with ease. But the more you demand from your surveys, the more places there are for tiny configuration errors to creep in, disrupting your fieldwork’s flow and maybe forcing projects to be paused or restarted. Issues such as routing errors, quota mismatches or reporting issues often only surface once surveys are already underway. Wouldn’t it be better if you could stress-test every survey before going live?

Meet the Nfield Interview Simulator

Nfield’s Interview Simulator enables you to put surveys to the test by running simulated interviews online using the same logic, quotas and sample integrations as real fieldwork. By feeding realistic data into your survey and letting it pass through every stage of the process, you can validate your setup before engaging respondents.

The significance of online simulation

Simulating interviews online is significantly better than running dummy data offline.

Traditional dummy data generation from NIPO ODIN Developer, which runs offline, randomly assigns answers to surveys. While useful for basic checks, this approach does not understand quotas, sample data or online logic — and the resulting data often lacks realism.

The Interview Simulator works differently. Simulated interviews are conducted identically to real online interviews, mimicking what happens when actual respondents provide data which moves all the way through your survey. This ensures far more meaningful validation and realistic test data.

Benefits of interview simulation

Running realistic data through your setup before going live delivers two important benefits:

1. Validating survey setup
Simulated interviews make it easy to verify routing, filtering and quota connections. These can confirm your script is correctly linked to quota variables, labels and logic.

2. Getting ahead of reporting requirements
Reporting increasingly needs to be ready from day one. Simulated interviews reveal realistic expectations of the data your survey is likely to deliver, so you can appropriately configure dashboards, cross tables and exports before fieldwork begins.

What the Interview Simulator can do

With simulated interviews you can:

Spot quota issues before they become fieldwork problems

Quota connection errors are one of the most common reasons for stopping live fieldwork. With the Interview Simulator, quota behavior is immediately visible. If a quota cell does not fill, the issue is often something simple — such as a mismatch between script variables and quota labels.

Identifying these issues before launch helps avoid costly delays and rework.

Use sample data in simulations

Unlike offline dummy data, the Interview Simulator understands sample data. This makes it possible to test surveys where routing or questions depend on values passed in from the sample, such as different paths for different groups.

You can use the sample from the original survey or upload a specific sample just for simulation. If your requested number of simulated interviews exceeds available sample records, the system clearly reports what happened.

Simulate with confidence

The Nfield Interview Simulator helps teams launch fieldwork with confidence. By validating routing, quotas, sample logic and reporting upfront, you reduce risk, save time and avoid unpleasant surprises once fieldwork is live.

To explore how to set up and use this feature in depth, with step-by-step technical guidance and examples, see the Interview Simulator documentation in the Nfield e-learning course. You might also find it useful to watch the corresponding session from Academy #46 – Simulate Interviews to see this feature in action.
