Overview
Executing large-scale
business surveys has been ERISS's specialty and focus since 1996. The
proprietary methodologies and accompanying technologies have all been
developed in-house and have reached unparalleled efficiencies.
The system has proven itself in more than 150 market surveys, involving
almost 2 million businesses in everything from small, rural areas
to large metropolitan areas including states. As a result, we have developed
a suite of custom programs and processes designed specifically for the
purpose.
When ERISS began
its survey work in 1996, it began collecting arguably the most difficult
type of business information there is: Exact staffing patterns with
specific pay scales, benefit offerings, experience and education requirements
and more.
At the time, the
one existing methodology for collecting this kind of information was
stratified random sampling. This approach simply did not provide enough
depth, breadth, or customization to be particularly useful for local
areas. In addition random sampling is expensive (when measured against
dollars per response) and very time consuming.
Working with top
scientists in the field, ERISS pioneered a breakthrough in methodology
- large-scale, census-style representative sample surveys using a technique
known as "stratified proportional quota sampling." The combination
of the census approach and sampling technique held the promise of solving
the primary problems of the old methodologies by providing enormous
amounts of both "deep" and "broad" local representative
data in a very short period of time.
To deal with massive
amounts of data generated by this new approach, ERISS built a whole
new suite of technologies - from sophisticated Computer Aided Telephone
Interview (CATI) systems and real-time validation, to dynamic targeting
systems and web delivery applications.
To cap it off, ERISS
built their Poway facilities around this new technology, resulting in
a state-of-the-art call center housing the most flexible and efficient
business survey system in existence and backed up by a highly experienced
team of technicians, engineers and scientists.
