Supplier Assessment

The assessment of a supplier occurs on many levels:

• by evaluating the quality of deliveries, by initial inspection (iQ-WEP, by standard receiving inspections iQ-EWEP and by repeated inspectionsiQ-EMP)
• by evaluating all complaints about supplier parts that have been discovered while mounting etc. or by customer complaints (iQ-QMS)
• by supplier audits, and by evaluating the supplier’s results of the previous year and estimating the potential for the following year.his last years’s results and his potential of the next year. These estimates are performed by the departments of purchasing, construction, logistics and quality assurance (iQ-AUDIT)

All individual modules supply compacted data about the supply quality to the modul iQ-LIEFBEW. Evaluation can be performed according to different aspects; standard surveys and statistics are available. They cover the most frequently used standard evaluations. Furthermore the user can answer his own questions in overviews, graphics or forms by using the module iQ-INFO.

General views

There are different perceptions

• delivery history of a supplier
  • supplied items of a supplier; single or summarized for a period
  • delivery reliability regarding items of a supplier
  • all supplies with a summary of the results
• delivery history of an item
  • all suppliers of an item with quality evaluation
  • mothly evaluation
  • hit list of suppliers
  • comparison of the delivery reliability of the suppliers

Inspection-based Quality Evaluation

• initial inspection
• reason of the inspection, e.g. primary delivery, new update index
• summarized measurements for each characteristic
• sample size
• reference to the inspection order
• use decision for functions and material, total use decision
• receiving inspection, event controlled and reviewed inspections
• inspection order, inspection plan
• summarized measurements for each character
• events that came up during inspection
• key quality data (VDA, Bosch)
• supplier reliability
• monthly statistics about QKZ, ppm
• ppm preconditions
• ppm statistics, compared with precondition
• reference to the inspection order
• several different material dispositions for each use decision
• presentation of quantity, disposition (free, for repair, to be sent back) and reason of complaint
• standard texts
• overviews of all inspection orders regarding the part/supplier relation; complete history of all deliveries
• initially received parts
• deliveries
• Skip lots, not inspected supplies
• reviewed inspections
• event driven inspections
• evaluation of one/of all suppliers for one part/for all parts
• Summarized evaluations for one supplier includes:

• supplier reliability
• appointment
• quantity
• price
• quality
• initially received parts
• serial parts
• reclamations
• customer complaints
• service, audit
• Bosch method
• consideration of initial inspections, receivings, production and customer complaints
• ranking by control parameters

Multiple Statistical Evaluations

• key quality data of the realations between suppliers and items on a monthly basis (and via versa)
• monthly statistic for ppm evaluations
• Pareto analysis for type of failure
• total evaluations about history and disposition
• list of the worst parts
• evaluations according to the Bosch method
• cycle time of the inspection lots
• overviews for items with ppm defaults
• delivery overviews for free statistical evaluations (export) with several selection criteria
• monthly statistics about complaints/comparison of suppliers
• user-defined evaluation; the customer can create statistics, graphics, forms and reports using the CRYSTAL REPORTS reporting software
