Questionnaire and implementation review
Validation of programmed instruments, routing, variables, codes and technical implementation before and during field launch.
MARKET & MEDIA RESEARCH
Independent quality assurance for complex research data.
We review survey and data processes, identify errors early and turn heterogeneous raw inputs into consistent, technically robust datasets.

SERVICES
Quality is not added at the end.
We secure critical transitions from questionnaire implementation and fieldwork to final data delivery. Modules can be commissioned separately or as a continuous control path.
Fieldwork monitoring
Ongoing control of field progress, quotas, structures and anomalies across one or several suppliers.
Interview quality controls
Review of defined quality criteria, including geolocation, interview sequences and project-specific requirements for telephone surveys.
Data checking and cleaning
Plausibility, consistency and structure checks with traceable error handling and documented corrections.
Weighting and structure validation
Development, implementation and independent validation of weighting procedures, target and actual structures, and key metrics.
Technical data production
Transformations, additional variables, code plans, tabulation, data reorganisation and defined delivery formats – including specialised legacy formats.
APPROACH
Automation with accountable expert review.
Technical routines provide speed and reproducibility. Expert judgement determines whether a finding is plausible and how it must be addressed.
- 01
Define the review
Clarify data flows, responsibilities, review criteria, interfaces and deliverables.
- 02
Build the control path
Implement project-specific checks, independent calculations and outputs in a reproducible manner.
- 03
Review and report continuously
Prioritise anomalies, assess them methodologically and resolve them transparently with all parties.
- 04
Secure final delivery
Deliver consistent, quality-checked and documented datasets that can be reliably processed and analysed.
TYPICAL USE CASES
Where an independent control layer adds particular value.
MULTIPLE SUPPLIERS
Studies involving several fieldwork or data partners
One consistent QA logic across different systems, institutes and delivery formats.
METHODOLOGY CHANGE
Migrations and hybrid measurement systems
Old/new process comparison, independent calculation and validation of transitions and calibration.
CRITICAL DELIVERY
Complex data production under time pressure
Validation, cleaning and transformation of heterogeneous inputs into a defined delivery dataset.
REPEATED STUDIES
Long-running and repeated studies
Consistent quality rules across waves, years and changing research conditions.
LIMITED START
Start with a clearly defined quality check.
An initial engagement can be limited to one implementation, one delivery run, one weighting procedure or a defined part of the process chain. The outcome and need for follow-up are evaluated together – without an unnecessarily large initial project.

Specialist expertise from more than five decades of research data.
interlogic Computer-Service GmbH was founded in 1969. The company combines methodological experience in market and media research with technical data processing and software development.
Our work is geared towards long-term project responsibility, traceable review processes and flexible collaboration with clients, research institutes and other data partners.
A consistent team supports projects directly and over extended periods. Methodological decisions, technical implementation and feedback therefore remain closely connected.
