VALID RESEARCH yearly carries out several hundred
surveys with 100.000 to 200.000 interviews. This can only be managed
with a very good team of interviewers.
A dense net of interviewers
With about 1.500 interviewers, all over Germany, we
have a very dense net, which makes efficient studies possible.
We´ll never let untrained interviewers work
for VALID RESEARCH, They have to fulfill a responsible task and
will usually have expensive equipment (pen-computer-system) at their
It is evident, that written and personal training
is necessary. VALID RESEARCH will support newcommers through supervisors
or very experienced interviewers. Our field density and the outstanding
use of field capacity make economically sensible solutions possible.
The interviewers of VALID RESEARCH more often than
not do surveys in the outlets of our customers; in department-stores,
supermarkets, perfumeries and drug-stores, in DIY and Cash&Carry
markets. In Fast-Food-stores, shopping centres and bank-branches.
We take care, that the image of our customers is protected.
A lot of our studies in trading (POS-Surveys) are
fixed to certain week days and partially bound to questions of an
exactly timing. Constant communication with our interviewers makes
sure that the demands can bet met.
Our interviewers and espacially our supervisors are
not only trained to use the equipment and the questionnaires correctly,
but also know how to manage the small problems of everyday fieldwork.
During the fieldwork (CAPI-surveys) we already test
the performance of the interviewers. Not only the number of achieved
interviews, but also their quality. The computer-technique makes
The mobile computer saves the data and time of every
interview, even every question. Manipulation is impossible.
At household- and business-to-business surveys written
controlling (up to 70% returned) is the norm. We control 50% of
all interviews at random.
Supply of findings
The carrying out of computer-assisted surveys means
that data entry (keypunching) is unnecessary. VALID RESEARCH can
have the data transfered by modem (if it is needed quickly) or after
the survey has been concluded. Out of this data we can produce the
final tables in a matter of hours
If the paper-pencil-interview seems suitable for the
project: VALID RESEARCH has an efficient coding-and-data entry-department.
VALID RESEARCH gets the surveyed data by CAPI-system
twice: First on the computer hard disk and also on a SRAM-memory
card, which is sent seperately. We never lost data.
