› Total "System" calibration vs individual component calibration

I work in the R&D department of a manufacturing concern. We are in the process of upgrading some equipment. The work will be done by an outside contractor. This equipment consists of a specialzied invironmental room with many volt/amp/watt/watthour/pressure/temperature transducers. Over the years we have developed calibration methods which peridocially apply an external excitation source to all the transducers individually and each is adjusted as necessary to bring it's output within specifications. This process has been automated to a good extent. During this upgrade we have the option to change to a "System" calibration. As I understand it, a load will be applied to each transducer under control of the rooms acquisition computer. Rather than adjust transducers, a polynomial calculation will be used to linerize the output of the transducers. The formula would then be used in each scan of the acquistion system to produce supposedly superior accuracy. I can see that this might be a better and faster method, but are their any drawbacks to this type of calibration other than purchase of new standards? Thanks for any advice or points to helpful online sights.

Hello Johnson,

Many of the six-sigma tools can be applied to deploying or implementing ISO 9001:2000. Some of the potential clauses we have identified where six sigma tools can be applied are:
4.0-Quality Management System: SS tools-SIPOC analysis, Process Maps/flowcharts

5.2-Customer Focus/Satisfaction: SS Tools-CTQ Trees

7-Product Realization: SS Tools-Identify process input and output requirements (SIPOC analysis, Process flowchart/maps); Verification and validation of processes/products (Process sigma, control charts,run charts); Identification, assessment and mitigation of risk (FMEAs); Design and development of products/services (DOEs)

8.0 Measurement, Analysis and Improvement: SS Tools-Ogranize customer data from surveys (Affinity diagram); Link VOC data and establish measures (CTQ trees); Facilitation of internal audits (SIPOC/Process maps); Monitoring and measuring of processes(Control charts, Process sigma, run charts); Identify, prioritize and implement corrective action (Cause & Effect tree, Hypothesis testing, Prioritization & Implementation matrices); Identify, prioritize and implement preventive action (FMEAs, prioritization and implementation matrices).

This list takes the view from 30,000 feet. I am sure a more in depth analysis would yield even more correlation between six sigma tools and ISO 9001:2000.
