QMDS from Stochos: "ISO 9000 in a Box" and More
QMDS has all the major tools you need to implement and maintain an ISO 9000-compliant quality management system (QMS). It error-proofs many activities such as document control, gage calibration, and preventive maintenance.
QAR (Quality Action Reporting) from Stochos (Included in QMDS)
Information from, 8 November 2002
    "The QAR incorporates all types of  Quality issues (Customer, Vendor, In-Process, Safety, Quality Audit, etc.) into a closed-loop system that requires action from all appropriate personnel."
    "The QAR tracks the following steps; Initiation, Notification to the Responsible Party, Disposition of Materials, Disposition Sign-off, Root Cause Analysis, Corrective Action Definition and Sign-off, and Verification of Corrective Action Effectiveness."
    Specific benefits:
    • Issues cannot "fall between the cracks."
    • Information sharing between management and the shop floor
    • Elimination of paperwork
PPI (Proactive Process Improvement) from Stochos
Proactive Process Improvement (PPI) is best described as nonparametric (i.e. it doesn't depend on a statistical regression or ANOVA model) and automated evolutionary optimization (EVOP).

PPI differs from Design of Experiments (DOE) in that DOE is an offline technique. In other words, you can rarely perform DOE on product that you intend to ship to your customers because the experimental conditions might be outside the normal specifications. Differences in factor levels (e.g. in a factorial or fractional factorial design) must often be substantial to identify key design variables, and such differences are often unacceptable in a running process.

There is an important tie-in here to Goldratt's Theory of Constraints (TOC).

PPI is an online technique that can be used while the process is running, and without interfering with its normal operation. It makes gradual and incremental changes in the process that, while remaining within specification, drive the process toward an optimum.
