What we do
Each engagement is built around one question: will the numbers survive scrutiny from the client, the donor and the reviewer? We cover the full survey cycle or step in at the stage you need.
Sampling design and weighting
Multi-stage probability samples, sample size and power, household and respondent selection, and weights that project results to the right population.
PPS · proportional allocation · Kish grid · rake weighting · post-stratification
Impact and performance evaluation
Baseline, midline and endline studies for randomized and non-experimental designs, with mixed methods where the questions call for them.
RCT · results frameworks · KII · FGD · difference testing
Questionnaire design and translation
Instruments that measure what they claim to. Every translation is back-translated, then cognitively tested and piloted before fieldwork.
KAP · UAI · cognitive testing · pre-tests · field manuals
CAPI and CATI set-up
Scripted instruments with validation at capture, visit tracking and call management, so errors are stopped in the field instead of found later.
SurveyToGo · phone surveys · GPS stamping · audio checks
Data cleaning and verification
Consistency checks tested against the real data, flags traced to individual case IDs, and raw files left untouched. Corrections are documented separately.
SPSS syntax · Python · skip-logic audits · cleaning reports
Media audits and market research
Media reach and trust for SBCC strategy, plus consumer studies for product, brand and service decisions across FMCG, telecom and banking.
media audits · CLT · sequential monadic · driver analysis
Standards we don’t negotiate
Clients hire us for the result. These are the habits that make the result defensible.
Translation and back-translation, or nothing
No interviewer interprets a question on the spot. Every language version is translated, back-translated and reconciled before it reaches a respondent.
Enumerators learn the instrument from its authors
No cascade training. Interviewers hear the questionnaire once, from the people who wrote it, and are certified before deployment.
Quality is built during collection
Validation at capture, GPS stamps, listening-in against audio, back-checks and live progress indicators. Problems are caught while the team is still in the field.
Every flag traces to a case
Raw data is never overwritten. Each anomaly is classed as an error, a legitimate non-response, a design feature, or unresolved, and unresolved items go back to the client as documented queries.
Everyone trained is deployed
We do not over-recruit trainees and cut down to the best. Interviewers are trained to a certification standard, and attrition is covered from an experienced standing field force.
No promise the budget doesn’t fund
Every commitment in a proposal traces to a cost line. Exclusions and assumptions are stated in writing, and inconsistencies in a terms of reference are flagged and resolved with the client before work begins.
