Throughout
the production process, RMS Int'l pursues a rigid
quality-control policy. Testing is carried out according to
internal and external standards laid down in a quality plan, and
we apply statistical methods to ensure process capability:
Our quality assurance system was first implemented
according to ISO 9001 in 1994. A subsequent audit in January
2000 earned RMS Int'l certification under the most recent ISO
9001:2000 standard, which ensures especially efficient process
orientation and environmentally compatible production. |
|
| |
|
And
finally, we exploit the advantages of supply chain management (SCM)
to control the whole of the information and supply chain,
applying a holistic logistics model so as to deliver finished
products to customers directly in as short a time as possible
and without interim storage. |

Strict
Quality Policy
RMS Int'l has established incoming,
in-process, and outgoing inspections to meet the needs of our
customers.
The incoming inspection is performed
according to DIN 40080 AQL 0,65. To ensure that the actual
inspection documents are always available, RMS
Int'l uses a common quality network with a
CAQ-System (Computer Aided Quality System). All inspectors in
our facilities use the inspection documents from this system.
This system enables us to analyze supplier performance, see how
the suppliers are ranked (A, B or C) and inform the supplier
immediately if the quality level of the delivered parts has
decreased.
Our goal is to eliminate potential
defects early in the design stage. Our suppliers are audited
when a new project starts in order to determine if the process
is reliable. Even if we try to eliminate defects during the
design stage and the supplier process audit, the finished goods
must still be inspected during the production process. All
operators are trained according to ISO 9001 and our internal
training plan, and they have the ability to work at different
work stations. This kind of strategy ensures flexible production
and quality that meets customer requirements.
To determine whether a defect can occur in the production
process, RMS Int'l established a
100% - functional and electrical inspection. This test is
performed on production lines with high quality inspection
equipment (FOTO), developed especially in accordance with the
needs of the customer. To obtain reliable data from the
inspection equipment, a Gauge R&R is performed; to ensure
the measurement method of the inspectors, we perform an
attributive Gauge R&R.
To ensure process flow, we implement SPC (Statistical Process
Control) and analyze the Cpk (process capability). If a
deviation occurs, corrective actions are introduced immediately.
To ensure the traceability and delivered
quality of all our products, RMS Int'l has
set up an outgoing inspection according to AQL 0.65 Level II.
All the necessary data are recorded in computers, and the
inspection is performed by highly skilled quality technicians.
We are committed to production and
delivery of perfect quality and the reduction of potential
defects, from the design stage, to our suppliers, all the way
through to our own production process.
We don't want to inspect quality; we produce it.

Statistical
Methods
RMS Int'l uses statistical methods
from the design stage through delivery of the end product to the
customer.. We use Design FMEA (Failure Mode and
Effects Analysis) in the design stage to eliminate potential
defects that may develop even at that early point.
Before the product is released for mass-production, our
engineers from the design, quality and production departments
perform a Process FMEA to pinpoint potential defects, starting
with incoming goods and ending on-site at the customer's
premises. During mass-production, we use SPC (Statistical
Process Control) for all big projects and the important
dimensions are measured [Editor's Note: text unclear; could mean::
During mass production, we use SPC (Statistical Process Control)
to measure important dimensions for all big projects.]. The
recorded data are used to analyze the Cpk-value, and if a
deviation in the process is found, corrective actions are
introduced immediately. |

Six
Sigma
RMS Int'l has used Six Sigma
methodology from year one. This was implemented in order to
achieve high quality and performance targets by introducing new
ways of thinking, and using new tools and methods (Six Sigma).
Six Sigma methodology is based on four
steps: Measurement, Analysis, Improvement, Control. These four
steps are applied to the following: Practical Problems,
Statistical Problems, Statistical Solutions and Practical
Solutions.
Measurement
In this step, we develop a focused problem statement, a process
map, and the process FMEA. The process response variables are
defined along with the method of measuring these variables. It
is then necessary to analyze the measurement system capability.
If this shows a positive result, the initial process capability
is established.
Analysis
In this step, the process response is characterized by using
normal distribution of recorded data and other graphic
analytical methods and tools. The statistical problem is
identified.

Distribution
Improvement
After identifying the statistical problem, in this step we
determine the input variables which are influencing the
output. Using DOE (Design of Experiments), we move the
distribution and shrink the spread for solving the statistical
problems and determine how the input influences the response
variables.

DOE Analysis
Control
In this step, the results of the DOE are confirmed. In addition,
the process itself is checked by using the results of the DOE. To
determine the end result, the final feasibility of the process is
checked again. All necessary data are recorded and the results are
conveyed to other staff members.
Ultimately, use of Six Sigma Methodology
provides a big benefit for RMS Int'l :
· Improvement of manufacturing process
· Improvement of quality
· Financial impact
