Planning fieldwork

A fieldwork plan translates the study's evidence needs into a feasible sequence of visits, interviews, observations, quality checks, and follow-up. It should explain who will be reached, how they will be selected, which conditions could exclude them, and how the team will respond. The plan protects both the credibility of the evidence and the time and welfare of participants and staff.

Plan around the research design

Define the populations and units before allocating interview targets. A household questionnaire, a worker interview, a facility observation, and a focus-group discussion answer different questions. Probability survey selections follow their sampling frame; purposive interviews follow an explicit rationale for including relevant experiences.

Use the sampling guide to specify survey precision and selection. Use the questionnaire and fieldwork guide to develop modules, respondent eligibility, translation, and pilot procedures. Record which measures must remain comparable across sites and rounds, and which local questions can adapt.

Estimate capacity from a pilot

Measure the time needed for introductions, consent, respondent selection, each module, travel, breaks, upload, and correction. Test the difficult routes and language arrangements, as well as the easiest interviews. Account for market days, agricultural work, school schedules, religious events, tides, and seasonal access where relevant.

For illustration, four enumerators completing four interviews on each of 15 interviewing days would produce 240 completed interviews. Those values are planning assumptions. Revisit days, failed contacts, training, supervision, and transit can reduce the number of productive days or completions. Compare several scenarios and allocate a contingency rather than promising the arithmetic maximum.

Interview capacity does not establish a confidence level or margin of error. Nor does interviewing many people in group sessions turn those participants into a probability sample. The historical Maluku field-planning material records a particular proposed itinerary; its staffing and throughput assumptions require fresh assessment before reuse.

Assign responsibilities and rehearse

Give responsibility for sample control, logistics, safeguarding, supervision, and data review to named roles. Facilitating a discussion and recording it are separate tasks. Plan interpreters and relevant language skills, and review how staff relationships with participants might influence responses.

Rehearse identification of selected units, consent explanations, neutral probing, sensitive questions, and interruption or withdrawal. Pilot the instruments and the complete delivery process, including offline collection, charging, synchronization, and correction of flagged records. The DIME handbook, chapter 4, distinguishes content and data pilots and recommends preparing quality checks before collection starts.

Meet community representatives to explain the study and arrange access, while providing ways for people to participate without gatekeepers choosing every respondent. Offer appropriate times and accessible venues. Plan confidential interviews where group discussion would expose a participant's circumstances or create pressure to agree. Explain the actual limits of confidentiality in a group.

Track implementation and quality

Maintain a controlled tracking record for every selected survey unit: attempts, eligibility, completion, refusal, temporary absence, and unresolved outcome. Follow the agreed revisit procedure. Any replacement rule belongs in the design and audit trail; fieldworkers should not improvise substitutions to meet a daily target.

Review daily progress against the intended sample and coverage. Combine automated checks with supervised observation and targeted or randomly selected back-checks. Resolve problems promptly, document changes, and avoid feedback that rewards speed or preferred answers. The World Bank's data quality assurance guidance treats instrument design, field management, and frequent checks as connected responsibilities.

Close the fieldwork cycle

Reserve time for team debriefs, participant questions, outstanding data requests, and verification of unresolved observations. Return an accessible account of findings through an agreed channel, while protecting confidential contributions. Record incidents, inaccessible locations, language gaps, and departures from the plan so that the analysis can describe what was actually achieved.

The fieldwork record should support the final coverage statement and explain remaining uncertainty. Preserve its link to the processing workflow and the methods references.
